C'è un modo per mostrare Google Admob in Android Recycler View

Question

Voglio mostrare gli annunci utilizzando google Admob nella mia attività principale della mia app. Ho messo tutto il codice necessario per mostrare gli annunci ottenendo aiuto dal sito di google-developers ma quando eseguo la mia app, gli annunci non vengono visualizzati. Non so qual è il problema che si verifica:

MainActivity:

import android.content.Context; 
import android.content.DialogInterface; 
import android.content.Intent; 
import android.net.ConnectivityManager; 
import android.net.NetworkInfo; 
import android.os.Bundle; 
import android.support.v7.app.AlertDialog; 
import android.support.v7.app.AppCompatActivity; 
import android.support.v7.widget.LinearLayoutManager; 
import android.support.v7.widget.RecyclerView; 
import android.view.Menu; 
import android.view.MenuItem; 
import android.view.View; 
import android.widget.Button; 
import android.widget.TextView; 
import android.widget.Toast; 

import com.google.android.gms.ads.AdRequest; 
import com.google.android.gms.ads.AdView; 

public class MainActivity extends AppCompatActivity { 
    public RecyclerView mRecyclerView; 
    private RecyclerView.Adapter mAdapter; 
    private RecyclerView.LayoutManager mLayoutManager; 
    private View view; 
    private Button button; 


    String[] mDataSet = new String[]{ 
      "1","2" 
    }; 

    String[] data = new String[]{"Sample Activty " 

    }; 
    private Context context; 
    private Intent sharingIntent; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     AdView mAdView = (AdView) findViewById(R.id.adView); 
     AdRequest adRequest = new AdRequest.Builder().build(); 
     mAdView.loadAd(adRequest); 

    mRecyclerView = (RecyclerView) findViewById(R.id.my_recycler_view); 
     mRecyclerView.addOnItemTouchListener(
       new RecyclerItemClickListener(context, new RecyclerItemClickListener.OnItemClickListener() { 
        @Override 
        public void onItemClick(View view, int position) { 
         // do whatever 
         Toast.makeText(view.getContext(), "position = " + position, Toast.LENGTH_SHORT).show(); 

} 
         context.startActivity(intent); 
        } 
       }) 
     ); 

// use a linear layout manager 
     LinearLayoutManager mLayoutManager = new LinearLayoutManager(this); 
     mLayoutManager.setOrientation(LinearLayoutManager.VERTICAL); 
     mRecyclerView.setLayoutManager(mLayoutManager); 

     mRecyclerView.addItemDecoration(new SimpleDividerItemDecoration(getResources())); 

     // specify an adapter (see also next example) 
     mAdapter = new MyAdapter(mDataSet); 
     mRecyclerView.setAdapter(mAdapter); 

e questo è MyAdapter.java:

import android.content.Context; 
import android.content.Intent; 
import android.nfc.Tag; 
import android.support.v7.widget.RecyclerView; 
import android.util.Log; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.AdapterView; 
import android.widget.TextView; 
import android.widget.Toast; 

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> { 
    // private String[] mDataset; 
    public String[] mDataset; 
    private String mItem; 
    private Context context; 

    AdapterView.OnItemClickListener itemClickListener; 

    // Provide a reference to the views for each data item 
    // Complex data items may need more than one view per item, and 
    // you provide access to all the views for a data item in a view holder 
    public class ViewHolder extends RecyclerView.ViewHolder { 
     // each data item is just a string in this case 
     public TextView mTextView; 
     public TextView mFootView; 

     public ViewHolder(View v) { 
      super(v); 
      // context = v.getContext(); 
      mTextView = (TextView) v.findViewById(R.id.firstLine); 
      // mFootView= (TextView) v.findViewById(R.id.secondLine); 
     } 
    } 
    // Provide a suitable constructor (depends on the kind of dataset) 
    public MyAdapter(String[] myDataset) { 
     mDataset = myDataset; 
    } 

    // Create new views (invoked by the layout manager) 
    @Override 
    public ViewHolder onCreateViewHolder(ViewGroup parent,int viewType) { 
     // create a new view 
     View v = LayoutInflater.from(parent.getContext()) 
       .inflate(R.layout.item_main, parent, false); 
     // set the view's size, margins, paddings and layout parameters 
     ViewHolder vh = new ViewHolder(v); 
     return vh; 
} 
    // Replace the contents of a view (invoked by the layout manager) 
    @Override 
    public void onBindViewHolder(ViewHolder holder, int position) { 
     // - get element from your dataset at this position 
     // - replace the contents of the view with that element 
     holder.mTextView.setText(mDataset[position]); 
    } 

    // Return the size of your dataset (invoked by the layout manager) 
    @Override 
    public int getItemCount() { 
     return mDataset.length; 
     // return mDataset.size(); 
    } 
} 

E questo activity_main.xml

<?xml version="1.0" encoding="utf-8"?>

Ecco completo esempio . Ho appena creato un'app di esempio per te.

Main Activity

import android.content.Context; 
import android.os.Bundle;

    private Context mContext; 
    private List<MyListModel> mList; 
    private RecyclerView mRecyclerView; 
    private RecyclerView.Adapter mAdapter; 
    private RecyclerView.LayoutManager mLayoutManager; 
    private Toolbar toolbar; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 
     mContext = this; 
     toolbar = (Toolbar) findViewById(R.id.toolbar); 
     setSupportActionBar(toolbar); 


     mRecyclerView = (RecyclerView) findViewById(R.id.recycler_view); 
     mList = new ArrayList<MyListModel>(); 

     for(int i=0;i<10;i++){ 
      MyListModel myString = new MyListModel(); 
      myString.setName(i+" - I love Paris"); 
      myString.setViewType(1); 
      mList.add(myString); 
     } 

     //Place two Admob Ads at position index 1 and 5 in recyclerview 
     MyListModel myString1 = new MyListModel(); 
     myString1.setViewType(2); 
     mList.add(1,myString1); 

     MyListModel myString2 = new MyListModel();
