RecyclerView with multiple View Type | RecyclerView with different view types | View Pager inside RecyclerView

Hello Friends,
              Today I am going to share my another android tutorial, with the help
of this we can easily create a Recyclerview with multiple different types
of view .
Also this tutorial helps you to create a View pager inside RecyclerView,


























1. MainActivity.java :

package com.developer.solutions.recyclerviewwithmultipleviewtype.activity;

import android.app.Activity;
import android.content.Intent;
import android.os.Binder;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.DefaultItemAnimator;
import android.support.v7.widget.LinearLayoutCompat;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.OrientationHelper;
import android.support.v7.widget.RecyclerView;
import android.support.v7.widget.Toolbar;
import android.widget.TextView;

import com.developer.solutions.recyclerviewwithmultipleviewtype.R;
import com.developer.solutions.recyclerviewwithmultipleviewtype.adapter.MultiViewTypeAdapter;
import com.developer.solutions.recyclerviewwithmultipleviewtype.model.Data;

import java.util.ArrayList;

import butterknife.BindView;
import butterknife.ButterKnife;
import butterknife.Unbinder;

public class MainActivity extends AppCompatActivity {

    Activity mActivity;
    @BindView(R.id.toolbar)
    Toolbar toolbar;
    @BindView(R.id.rv)
    RecyclerView mRecyclerView;
    Unbinder mUnbinder;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //((TextView) findViewById(R.id.tv)).setText("Welcome user");
        mUnbinder = ButterKnife.bind(this);

        ArrayList list = new ArrayList<>();
        list.add(new Data(Data.VIEW_PAGER, "Hello. This is the View Pager view type with images", 0));
        list.add(new Data(Data.IMAGE_TYPE, "A view type with Image and Textview", R.drawable.disneys_cinderella));
        list.add(new Data(Data.AUDIO_TYPE, "Hey, A view type with Button and Textview", 0));
        list.add(new Data(Data.IMAGE_TYPE, "Hi again. A view with Image and Textview", R.drawable.snow));

        MultiViewTypeAdapter adapter = new MultiViewTypeAdapter(list, this);
        final LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this);
        linearLayoutManager.setOrientation(LinearLayoutManager.VERTICAL);
        mRecyclerView.setLayoutManager(linearLayoutManager);
        mRecyclerView.setItemAnimator(new DefaultItemAnimator());
        mRecyclerView.setAdapter(adapter);
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
         if (mUnbinder != null) mUnbinder.unbind();
    }
}

Android Retrofit With RX Java Sample | Android Retrofit Example

Hello Friends,

This is an simple example of How we use Android Retrofit With RX .  I hope this
will helps you to start using Retrofit and  RX together.
