क्या एंड्रॉइड रीसाइक्लर में Google Admob दिखाने का कोई तरीका है

Question

मैं अपने ऐप की मुख्य गतिविधि में Google Admob का उपयोग करके विज्ञापन दिखाना चाहता हूं। मैंने Google- डेवलपर साइट से सहायता प्राप्त करके विज्ञापनों को दिखाने के लिए सभी कोडों को रखना आवश्यक है, लेकिन जब मैं अपना ऐप चलाता हूं, तो विज्ञापन प्रदर्शित नहीं होते हैं। मैं नहीं पता है कि समस्या क्या होने वाली है:

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); 

और यह MyAdapter.java है:

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(); 
    } 
} 

और यह activity_main.xml

यहाँ पूरा उदाहरण है । मैंने अभी आपके लिए एक उदाहरण ऐप बनाया है।
