我想在我的应用的主要活动中使用Google Admob展示广告。我已经通过谷歌开发者网站获得帮助来显示所有显示广告的代码,但是当我运行我的应用时,广告没有显示。我不知道发生了什么问题:

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);

这是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();
   }
}

这是activity_main.xml

这是完整的例子。我刚刚为你创建了一个示例应用程序。
