Android media store tutorial | List all sdcard audio |List all sdcard video | List all sdcard images

Hello Friends,
       Today, I am going to share my another post on Android Media Store. In this post
I am going to show you how to query media file like audio,images and video using
Android Media Store and Android Content Resolver .









For Listing all Images:
private void parseAllImages() {
        try {
            String[] projection = {MediaStore.Images.Media.DATA};
            cursor = getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                    projection, // Which columns to return
                    null,       // Return all rows
                    null,
                    null);

          
            int size = cursor.getCount();

            /*******  If size is 0, there are no images on the SD Card. *****/

            if (size == 0) {

            } else {

                int thumbID = 0;
                while (cursor.moveToNext()) {

                    int file_ColumnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);

                    /**************** Captured image details ************/

                    /*****  Used to show image on view in LoadImagesFromSDCard class ******/
                    String path = cursor.getString(file_ColumnIndex);

                    String fileName = path.substring(path.lastIndexOf("/") + 1, path.length());

                    MediaFileInfo mediaFileInfo = new MediaFileInfo();
                    mediaFileInfo.setFilePath(path);
                    mediaFileInfo.setFileName(fileName);
                    mediaFileInfo.setFileType(type);
                    mediaList.add(mediaFileInfo);
                }
            }


        } catch (Exception e) {
            e.printStackTrace();
        }
} 


For Listing all Video(.mp4)


private void parseAllVideo() {
        try {
            String name = null;
            String[] thumbColumns = {MediaStore.Video.Thumbnails.DATA,
                    MediaStore.Video.Thumbnails.VIDEO_ID};

            int video_column_index;
            String[] proj = {MediaStore.Video.Media._ID,
                    MediaStore.Video.Media.DATA,
                    MediaStore.Video.Media.DISPLAY_NAME,
                    MediaStore.Video.Media.SIZE};
            Cursor videocursor = getContentResolver().query(MediaStore.Video.Media.EXTERNAL_CONTENT_URI,
                    proj, null, null, null);
            int count = videocursor.getCount();
            Log.d("No of video", "" + count);
            for (int i = 0; i < count; i++) {
                MediaFileInfo mediaFileInfo = new MediaFileInfo();
                video_column_index = videocursor
                        .getColumnIndexOrThrow(MediaStore.Video.Media.DISPLAY_NAME);
                videocursor.moveToPosition(i);
                name = videocursor.getString(video_column_index);

                mediaFileInfo.setFileName(name);

                int column_index = videocursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
                videocursor.moveToPosition(i);
                String filepath = videocursor.getString(column_index);

                mediaFileInfo.setFilePath(filepath);
                mediaFileInfo.setFileType(type);
                mediaList.add(mediaFileInfo);
                // id += " Size(KB):" +
                // videocursor.getString(video_column_index);


            }
            videocursor.close();

        } catch (Exception e) {
            e.printStackTrace();
        }
} 



For Listing All Audio


private void parseAllAudio() {
        try {
            String TAG = "Audio";
            Cursor cur = getContentResolver().query(
                    MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, null, null, null,
                    null);

            if (cur == null) {
                // Query failed...
                Log.e(TAG, "Failed to retrieve music: cursor is null :-(");

            }
            else if (!cur.moveToFirst()) {
                // Nothing to query. There is no music on the device. How boring.
                Log.e(TAG, "Failed to move cursor to first row (no query results).");

            }else {
                Log.i(TAG, "Listing...");
                // retrieve the indices of the columns where the ID, title, etc. of the song are

                // add each song to mItems
                do {
                    int artistColumn = cur.getColumnIndex(MediaStore.Audio.Media.ARTIST);
                    int titleColumn = cur.getColumnIndex(MediaStore.Audio.Media.TITLE);
                    int albumColumn = cur.getColumnIndex(MediaStore.Audio.Media.ALBUM);
                    int durationColumn = cur.getColumnIndex(MediaStore.Audio.Media.DURATION);
                    int idColumn = cur.getColumnIndex(MediaStore.Audio.Media._ID);
                    int filePathIndex = cur.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
                    Log.i(TAG, "Title column index: " + String.valueOf(titleColumn));
                    Log.i(TAG, "ID column index: " + String.valueOf(titleColumn));

                    Log.i("Final ", "ID: " + cur.getString(idColumn) + " Title: " + cur.getString(titleColumn) + "Path: " + cur.getString(filePathIndex));
                    MediaFileInfo audio = new MediaFileInfo();
                    audio.setFileName(cur.getString(titleColumn));
                    audio.setFilePath(cur.getString(filePathIndex));
                    audio.setFileType(type);
                    mediaList.add(audio);

                } while (cur.moveToNext());
            }

        } catch (Exception e) {
            e.printStackTrace();
        }

Android Trusting all certificates using HttpClient over HTTPS| Access all secure and in-secure https connection in Android and Java

Hello Friends,
          Today, I am going to share a blog post on "HTTPS". Using this blog we can easily access all
secure and non secure "HTTPS" connection in java as well as android too.


1. Add "InSecureSSLSocketFactory.java" class

import java.io.IOException;
import java.net.Socket;
import java.net.UnknownHostException;
import java.security.KeyManagementException;
import java.security.KeyStore;
import java.security.KeyStoreException;
import java.security.NoSuchAlgorithmException;
import java.security.UnrecoverableKeyException;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;

import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;

import org.apache.http.conn.ssl.SSLSocketFactory;
public class InSecureSSLSocketFactory extends SSLSocketFactory {
    SSLContext sslContext = SSLContext.getInstance("TLS");

    public InSecureSSLSocketFactory(KeyStore truststore) throws NoSuchAlgorithmException, KeyManagementException, KeyStoreException, UnrecoverableKeyException {
        super(truststore);

        TrustManager tm = new X509TrustManager() {
            public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            }

            public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            }

            public X509Certificate[] getAcceptedIssuers() {
                return null;
            }
        };

        sslContext.init(null, new TrustManager[] { tm }, null);
    }

    @Override
    public Socket createSocket(Socket socket, String host, int port, boolean autoClose) throws IOException, UnknownHostException {
        return sslContext.getSocketFactory().createSocket(socket, host, port, autoClose);
    }

    @Override
    public Socket createSocket() throws IOException {
        return sslContext.getSocketFactory().createSocket();
    }
} 


2. Create a new HTTP client using the above InSecureSSLSocketFactory class, for making
     connection.

public HttpClient getNewHttpClient() {
    try {
        KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
        trustStore.load(null, null);

        InSecureSSLSocketFactory sf = new InSecureSSLSocketFactory(trustStore);
        sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

        HttpParams params = new BasicHttpParams();
        HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
        HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);

        SchemeRegistry registry = new SchemeRegistry();
        registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
        registry.register(new Scheme("https", sf, 443));

        ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);

        return new DefaultHttpClient(ccm, params);
    } catch (Exception e) {
        return new DefaultHttpClient();
    }
}
3. Finally hitting the service url(https://) using getNewHttpClient() , which helps to feth data
    from server.

public static String networkHitForGetJsonData(String url)
{
 String websiteData = null;
 try {
  HttpParams httpParameters = new BasicHttpParams();
  HttpConnectionParams.setConnectionTimeout(httpParameters, 10000);
  HttpClient client = getNewHttpClient();
  URI uri = new URI(url);
  HttpGet method = new HttpGet(uri);
  method.addHeader("Content-Type", "text/html");
  HttpResponse res = client.execute(method);
  InputStream data = res.getEntity().getContent();
  websiteData = generateString(data);
  Log.e("response","response---> "+websiteData);
 } catch (ClientProtocolException e) {
  e.printStackTrace();
  websiteData = null;
 } catch (IOException e)
 {
  e.printStackTrace();
  websiteData = null;
 } catch (URISyntaxException e)
 {
  e.printStackTrace();
  websiteData = null;
 }
 return websiteData;
}

Android add calendar event Programatically | Android Codes: Insertion and Deletion of Calendar Events | Configure email notification with Calendar app in Android

Hello Friends,
          Today, I am sharing my another android tutorial which covers following things:

1. Android- Adding events to calendar via your android application
2. Programmatically add reminder in android calendara
3. Configure email notification with Calendar app in Android


A. For adding event on Calendar

try {
 String eventUriString = "content://com.android.calendar/events";
 ContentValues eventValues = new ContentValues();
 eventValues.put("calendar_id", 1); // id, We need to choose from
     // our mobile for primary its 1
 eventValues.put("title", title);
 eventValues.put("description", desc);
 eventValues.put("eventLocation", place);

 long endDate = startDate + 1000 * 10 * 10; // For next 10min
 eventValues.put("dtstart", startDate);
 eventValues.put("dtend", endDate);

 // values.put("allDay", 1); //If it is bithday alarm or such
 // kind (which should remind me for whole day) 0 for false, 1
 // for true
  eventValues.put("eventStatus", status); // This information is
   // sufficient for most
   // entries tentative (0),
   // confirmed (1) or canceled
   // (2):
 eventValues.put("eventTimezone", "UTC/GMT +5:30");
 /*
  * Comment below visibility and transparency column to avoid
  * java.lang.IllegalArgumentException column visibility is invalid
  * error
  */
 // eventValues.put("allDay", 1);
 // eventValues.put("visibility", 0); // visibility to default (0),
   // confidential (1), private
   // (2), or public (3):
   // eventValues.put("transparency", 0); // You can control whether
   // an event consumes time
   // opaque (0) or transparent
   // (1).
 eventValues.put("hasAlarm", 1); // 0 for false, 1 for true

 Uri eventUri = curActivity.getApplicationContext()
    .getContentResolver()
    .insert(Uri.parse(eventUriString), eventValues);
 eventID = Long.parseLong(eventUri.getLastPathSegment()); 
} catch (Exception ex) {
 log.error("Error in adding event on calendar" + ex.getMessage());
}


B. Set Reminder for above added event id:

if (needReminder) {
/***************** Event: Reminder(with alert) Adding reminder to event *******************/
        String reminderUriString = "content://com.android.calendar/reminders";
 ContentValues reminderValues = new ContentValues();
 reminderValues.put("event_id", eventID);
 reminderValues.put("minutes", 5); // Default value 
       //set time in min which occur before event start   
 reminderValues.put("method", 1); // Alert Methods: Default(0),
     // Alert(1), Email(2),SMS(3)
 Uri reminderUri = curActivity.getApplicationContext()
      .getContentResolver()
    .insert(Uri.parse(reminderUriString), reminderValues);
}
 

C: Send mail to user for attending the meeting added on calendar

/***************** Event: Meeting(without alert) Adding Attendies to the meeting *******************/

if (needMailService) {
 String attendeuesesUriString = "content://com.android.calendar/attendees";

 /********
  * To add multiple attendees need to insert ContentValues
  * multiple times
  ***********/
 ContentValues attendeesValues = new ContentValues();
 attendeesValues.put("event_id", eventID);
 attendeesValues.put("attendeeName", "xxxxx"); // Attendees name
 attendeesValues.put("attendeeEmail", "yyyy@gmail.com");// Attendee email
 attendeesValues.put("attendeeRelationship", 0); // Relationship_Attendee(1),
       // Relationship_None(0),
       // Organizer(2),
       // Performer(3),
       // Speaker(4)
 attendeesValues.put("attendeeType", 0); // None(0), Optional(1),
      // Required(2),
      // Resource(3)
 attendeesValues.put("attendeeStatus", 0); // NOne(0),
          // Accepted(1),
        // Decline(2),
        // Invited(3),
        // Tentative(4)

 Uri eventsUri = Uri.parse("content://calendar/events");
 Uri url = curActivity.getApplicationContext()
    .getContentResolver()
    .insert(eventsUri, attendeesValues);

 // Uri attendeuesesUri = curActivity.getApplicationContext()
    // .getContentResolver()
    // .insert(Uri.parse(attendeuesesUriString), attendeesValues);
} 

D: For deletion of calendar event: Here "id" is event id.

Uri uri = ContentUris.withAppendedId(CALENDAR_URI, Integer.parseInt(id));
getContentResolver().delete(uri, null, null); 

Finally All together: Add this method in your activity class

public long addAppointmentsToCalender(Activity curActivity, String title,
   String desc, String place, int status, long startDate,
   boolean needReminder, boolean needMailService) {
/***************** Event: add event *******************/
long eventID = -1;
try {
        String eventUriString = "content://com.android.calendar/events";

 }
} catch (Exception ex) {
 log.error("Error in adding event on calendar" + ex.getMessage());
}

return eventID;

}
 

Also need to add following permission in your AndroidManifest.xml file

<uses-permission android:name="android.permission.READ_CALENDAR" />
<uses-permission android:name="android.permission.WRITE_CALENDAR" />

Android Read Status Bar Notification | Android Read all incoming notification | Android Read Incoming Sms | Android Read Incoming Call

Hello Friends,
    Today, I am going to share a small tutorial on android "NotificationListenerService"
    which help us to read the all app notifications. This tutorial covers following
    points.

 




Feature:
1. We can easily read the notification of other android application or read all status bar
     notification,
2. Read|Listen incoming whatsapp messages
3. Read all incoming SMS
4. Read all incoming calls
5. Battery Low

Step1 : Create a Notification Service Class :
                    This class extends NotificationListenerService class which contains
                    two method:
                 a) onNotificationPosted(StatusBarNotification sbn) :
                           Implement this method to learn about new notifications as they are
                           posted by apps.
                 b) onNotificationRemoved(StatusBarNotification sbn) :
                           Implement this method to learn when notifications are removed.                         

 Note: The StatusBarNotifcation object contains extras, app package name and
            ticker name

1. NotificationService.java

package android.notifications;

import android.app.Notification;
import android.content.Context;
import android.content.Intent;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.service.notification.NotificationListenerService;
import android.service.notification.StatusBarNotification;
import android.util.Log;
import android.support.v4.content.LocalBroadcastManager;

import java.io.ByteArrayOutputStream;

    }
    @Override

    public void onNotificationPosted(StatusBarNotification sbn) {
        String pack = sbn.getPackageName();

            ticker = sbn.getNotification().tickerText.toString();
        }
        Bundle extras = sbn.getNotification().extras;
        String title = extras.getString("android.title");
        String text = extras.getCharSequence("android.text").toString();
        int id1 = extras.getInt(Notification.EXTRA_SMALL_ICON);
        Bitmap id = sbn.getNotification().largeIcon;


        Log.i("Package",pack);
        Log.i("Ticker",ticker);
        Log.i("Title",title);
        Log.i("Text",text);

        Intent msgrcv = new Intent("Msg");
        msgrcv.putExtra("package", pack);
        msgrcv.putExtra("ticker", ticker);
        msgrcv.putExtra("title", title);
        msgrcv.putExtra("text", text);
        if(id != null) {
            ByteArrayOutputStream stream = new ByteArrayOutputStream();
            id.compress(Bitmap.CompressFormat.PNG, 100, stream);
            byte[] byteArray = stream.toByteArray();
            msgrcv.putExtra("icon",byteArray);
        }
        LocalBroadcastManager.getInstance(context).sendBroadcast(msgrcv);


    }

    @Override

    public void onNotificationRemoved(StatusBarNotification sbn) {
        Log.i("Msg","Notification Removed");

Android applying custom fonts

Hello Friends,
      Today, I am sharing my small blog which helps you in applying custom fonts
on android text view from xml or styles file. Its very easy and reduces the number
of java line from your code and also make the performance of your app more better.
                                     


Steps:
1.Placed all your custom fonts file inside assets folder i.e: assets/fonts/digitalism.ttf)
2.Add the path of above custom font file your string.xml file
<string name="FONT_d3_digitalism">fonts/d3-digitalism.ttf</string>
<string name="FONT_digitalism">fonts/digitalism.ttf</string>
<string name="FONT_Mohave_Bold">fonts/Mohave-Bold.ttf</string>
<string name="FONT_Roboto_Black">fonts/Roboto-Black.ttf</string>
<string name="FONT_Roboto_Bold">fonts/Roboto-Bold.ttf</string>
<string name="FONT_Roboto_Medium">fonts/Roboto-Medium.ttf</string>
<string name="FONT_RobotoCondensed_Bold">fonts/RobotoCondensed-Bold.ttf</string>

3. Declartion of style inside values/styles.xml file for eg:
        <style name="CustomDigital">
          <item name="font">@string/FONT_digitalism</item>
        </style>

4. Inside attrs.xml add this:
<?xml version="1.0" encoding="utf-8"?>
<resources>
      <declare-styleable name="Fontify">
<attr name="font" format="string" />
      </declare-styleable>

   <!-- Allows attribute use in an AppTheme definition -->
   <declare-styleable name="FontifyTheme">
<attr name="fontifyStyle" format="reference"/>
   </declare-styleable>
</resources>
5. finally, In our layout file we have to use this :
      <com.android.developer.solutions.font.TextClock
         android:id="@+id/textClock1"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:layout_alignLeft="@+id/btn"
         android:layout_alignRight="@+id/btn"
         android:layout_below="@+id/btn"
         android:layout_marginTop="20dp"
         android:gravity="center"
         android:textSize="18sp"
         style="@style/CustomDigital"
         android:text="TextClock" />

Whats New in Android Lollipop | Android lollipop new features


Hello Friends,
       Today, I am sharing about the
  feature added android latest
 version i.e:"Android Lollipop".
                       



1. Material design
A bold, colorful and responsive UI design for consistent, intuitive experiences across all
your devices.

-Android 5.0 brings Material design to Android and gives you an expanded UI toolkit for
 integrating the new design patterns easily in your apps.
-New 3D views let you set a z-level to raise elements off of the view hierarchy and cast 
  real time shadows, even as they move.
- Ripple animations are available for buttons, checkboxes, and other touch controls in 
   your app.
- Animated and non-animated drawables based on XML vector graphics
- A new system-managed processing thread called RenderThread keeps animations 
  smooth even when there are delays in the main UI thread.  
- The RecyclerView widget 
- Drawable animation and styling effects
- Material design animation and activity transition effects


2. Notifications
New ways to control when and how you receive messages – only get interrupted when
you want to be.
       

- View and respond to messages directly from your
   lock screen. Includes the ability to hide sensitive 
   content for these notifications.
- For fewer disruptions, turn on Priority mode via 
  your device’s volume button so only certain people
  and notifications get through.
- Or schedule recurring downtime, such as from 10.00 p.m. until 
   8.00 a.m., when only  Priority notifications can get through.
- With Lollipop, incoming phone calls won’t interrupt what you’re watching or playing. 
   You can choose to answer the call or just keep doing what you’re doing.
- Control the notifications triggered by your apps; hide sensitive content and priorities or
    turn off the app’s notifications entirely.
- See all your notifications in one place by tapping the top of the screen.

3. Battery
    Power for the long haul

- A battery saver feature that extends device use by up to 90 mins.
- Estimated time left to fully charge is displayed when your device is plugged in.
- Estimated time left on your device before you need to charge again can now be found
   in battery settings.

4. Security
    Keep your stuff safe and sound

- New devices come with encryption automatically turned on to help protect data on lost
  or stolen devices.
- Use Android Smart Lock to secure your phone or tablet by pairing it with a trusted device
  like your wearable or even your car.

5. Device sharing
    More flexible sharing with family and friends

- Multiple users for phones. If you forget your phone, you still can call any of your
   friends (or access any of your messages, photos, etc.)  by simply logging in to 
   another Android phone running Lollipop. Also perfect for families who want to share a
   phone, but not their stuff.
- Guest user for phones and tablets means you can lend your device and not your info
- Screen pinning: pin your screen so that another user can access just that content 
   without messing with your other stuff

6. Accessibility
    Enhanced low-vision and colour-blind capabilities.

- Boost text contrast or invert colours to improve legibility.
- Adjust display to improve colour differentiation.  


7. Media
    Bolder graphics and improved audio, video and camera capabilities.

- Lower latency audio input ensuring that music and communication applications 
   that have strict delay requirements provide an amazing realtime experience.
- Multi-channel audio stream mixing means professional audio applications can now
   mix up to eight channels including 5.1 and 7.1 channels.
- USB Audio support means that you can plug USB microphones, speakers and a
   myriad of other USB audio devices like amplifiers and mixers into your Android device.
- OpenGL ES 3.1 and Android extension pack brings Android to the forefront of
   mobile graphics putting it on par with desktop and console class performance.

8. Runtime and performance
   A faster, smoother and more powerful computing experience.

- ART, an entirely new Android run time, improves application performance and
   responsiveness.
- Up to 4x performance improvements.
- Smoother UI for complex, visually rich applications.
- Compacting backgrounded apps and services so that you can do more at once.

9. Connectivity
    A better Internet connection everywhere and more powerful Bluetooth low energy capabilities

- Improved network handoffs resulting in limited interruption in connectivity. For 
  example, continue your video chat or VoIP calls without interruption as
  you leave the house and switch from your home Wi-Fi back to mobile.
- Improved network selection logic so that your device connects only if there is a 
   verified internet connection on Wi-Fi.
- Power-efficient scanning for nearby Bluetooth low energy (“BLE”) devices like 
   wearables or beacons.
- New BLE peripheral mode.

10. OK Google
Easy access to information and performing tasks

- Even if your screen is off, you can say "OK Google" on devices with digital signal
   processing support such as Nexus 6 and Nexus 9.
- Talk to Google on the go to get quick answers, send a text, get directions and more.

11. Coming soon: Android TV
            Support for living room devices

- User interface adapted for the living room.
- Less browsing, more watching with personalised recommendations for content like
   films and TV shows.
- Voice search for Google Play, YouTube and supported apps so that you can just 
   see what you want to see.
- Console-style Android gaming on your TV with a gamepad.
- Cast your favourite entertainment apps to your big screen with Google Cast support
   for Android TV devices.

Android Custom Horizontal progress bar | Custom Progress bar

Hello Friends,
                  Today,I am going to share my another blog which helps you in customizing
Horizontal Progress Bar.With the help of this Android tutorial we can also implement
the Android PI Chart view with multiple color.

Actually my need to show some PI Chart like view with multiple different color which fills
dynamically base on the percentage,  without using any 3rd party library. So , I first go
with Horizontal progress bar but in horizontal progress bar only show up-to two level 
progress with different color.

Finally, I have written a custom progress bar code using android seek bar. Using this we
can add "N level" of different color with different percentage.And Its very simple and
easily understandable.

Horizontal Progress bar


Here is my code :

1. MainActivity.java

package com.android.customprogressbar;

import java.util.ArrayList;

import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;

public class MainActivity extends Activity {

 private CustomProgressBar seekbar;
 private ArrayList progressItemList;
 private ProgressItem mProgressItem;

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  seekbar = ((CustomProgressBar) findViewById(R.id.seekBar0));
  seekbar.getThumb().mutate().setAlpha(0);
  initDataToSeekbar();
 }

 private void initDataToSeekbar() {
  progressItemList = new ArrayList();
  // red span
  mProgressItem = new ProgressItem();
  mProgressItem.progressItemPercentage = 20;
  Log.i("Mainactivity", mProgressItem.progressItemPercentage + "");
  mProgressItem.color = R.color.red;
  progressItemList.add(mProgressItem);
  // blue span
  mProgressItem = new ProgressItem();
  mProgressItem.progressItemPercentage = 25;
  mProgressItem.color = R.color.blue;
  progressItemList.add(mProgressItem);
  // green span
  mProgressItem = new ProgressItem();
  mProgressItem.progressItemPercentage = 35;
  mProgressItem.color = R.color.green;
  progressItemList.add(mProgressItem);
  
  //white span
  mProgressItem = new ProgressItem();
  mProgressItem.progressItemPercentage = 20;
  mProgressItem.color =  R.color.white;
  progressItemList.add(mProgressItem);

  
  seekbar.initData(progressItemList);
  seekbar.invalidate();
 }

 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
  getMenuInflater().inflate(R.menu.main, menu);
  return true;
 }
}

2. CustomProgressBar.java


package com.android.customprogressbar;

import java.util.ArrayList;

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Paint;
import android.graphics.Rect;
import android.util.AttributeSet;
import android.widget.SeekBar;

public class CustomProgressBar extends SeekBar {

 private ArrayList mProgressItemsList;

 public CustomProgressBar(Context context) {
  super(context);
  mProgressItemsList = new ArrayList();
 }

 public CustomProgressBar(Context context, AttributeSet attrs) {
  super(context, attrs);
 }

 public CustomProgressBar(Context context, AttributeSet attrs, int defStyle) {
  super(context, attrs, defStyle);
 }

 public void initData(ArrayList progressItemsList) {
  this.mProgressItemsList = progressItemsList;
 }

 @Override
 protected synchronized void onMeasure(int widthMeasureSpec,
   int heightMeasureSpec) {
  // TODO Auto-generated method stub
  super.onMeasure(widthMeasureSpec, heightMeasureSpec);
 }

 protected void onDraw(Canvas canvas) {
  if (mProgressItemsList.size() > 0) {
   int progressBarWidth = getWidth();
   int progressBarHeight = getHeight();
   int thumboffset = getThumbOffset();
   int lastProgressX = 0;
   int progressItemWidth, progressItemRight;
   for (int i = 0; i < mProgressItemsList.size(); i++) {
    ProgressItem progressItem = mProgressItemsList.get(i);
    Paint progressPaint = new Paint();
    progressPaint.setColor(getResources().getColor(
      progressItem.color));

    progressItemWidth = (int) (progressItem.progressItemPercentage
      * progressBarWidth / 100);

    progressItemRight = lastProgressX + progressItemWidth;

    // for last item give right to progress item to the width
    if (i == mProgressItemsList.size() - 1
      && progressItemRight != progressBarWidth) {
     progressItemRight = progressBarWidth;
    }
    Rect progressRect = new Rect();
    progressRect.set(lastProgressX, thumboffset / 2,
      progressItemRight, progressBarHeight - thumboffset / 2);
    canvas.drawRect(progressRect, progressPaint);
    lastProgressX = progressItemRight;
   }
   super.onDraw(canvas);
  }

 }

}


2. ProgressItem.java
package com.android.customprogressbar;

public class ProgressItem {
 public int color;
 public float progressItemPercentage;
}
