Is there a way to show Google Admob in Android Recycler View

Question

I want to show ads using Google Admob in my application. The main activity. I put all the code to display ads, getting help from the Google developers site, but when I launch my application, the ads do not appear. I do not know what's the problem:

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); 

And this is 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 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(); } } 

And this activity_main.xml

 <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:ads="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:fitsSystemWindows="true" android:orientation="vertical" tools:context=".MainActivity" android:background="@drawable/main_redrose" > <!-- A RecyclerView with some commonly used attributes --> <android.support.v7.widget.RecyclerView android:id="@+id/my_recycler_view" android:layout_width="match_parent" android:layout_height="match_parent" android:scrollbars="vertical" android:divider="@drawable/list_divider"/> <com.google.android.gms.ads.AdView android:id="@+id/adView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerHorizontal="true" android:layout_alignParentBottom="true" ads:adSize="BANNER" ads:adUnitId="@string/banner_ad_unit_id"> </com.google.android.gms.ads.AdView> </LinearLayout>

Here is a complete example. I just created an example application for you.

Primary activity

 import android.content.Context; import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.support.v7.widget.LinearLayoutManager; import android.support.v7.widget.RecyclerView; import android.support.v7.widget.Toolbar; import java.util.ArrayList; import java.util.List; public class Main extends AppCompatActivity { public static final String TAG = Main.class.getSimpleName(); 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(); myString2.setViewType(2); mList.add(5,myString2); // use a linear layout manager mLayoutManager = new LinearLayoutManager(this); mRecyclerView.setLayoutManager(mLayoutManager); // specify an adapter (see also next example) mAdapter = new ListAdopter(this, mList); mRecyclerView.setAdapter(mAdapter); } } 

RecyclerViewAdopter

Mylistmodel

 public class MyListModel { private String name; private int viewType; public String getName() { return name; } public void setName(String name) { this.name = name; } public int getViewType() { return viewType; } public void setViewType(int viewType) { this.viewType = viewType; } }
