  <p>Here is myGridAdapter:</p>
  
  <pre><code>public class myGridAdapter extends BaseAdapter {
  
  private Context context;
  private String[] mobileValues;
  
  public myGridAdapter(MainActivity mainActivity, String[] arrayEmpty) {
      this.context = mainActivity;
      this.mobileValues = arrayEmpty;
  }
  
  public View getView(int position, View convertView, ViewGroup parent) {
  
      LayoutInflater inflater = (LayoutInflater) context
          .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
  
      View gridView;
  
      if (convertView == null) {
  
          gridView = new View(context);
  
          // get layout from text_item.xml
          gridView = inflater.inflate(R.layout.text_item, null);
  
          // set value into textview
          TextView textView = (TextView) gridView
                  .findViewById(R.id.grid_item_label);
          textView.setText(mobileValues[position]);
  
      } else {
          gridView = (View) convertView;
      }
  
      return gridView;
  }
  .....
  }
  </code></pre>
  
  <p>This is the XML for each text item </p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools"
  android:layout_width="match_parent"
  android:layout_height="fill_parent"
  android:gravity="center"
  android:orientation="vertical" &gt;
  
  &lt;TextView
      android:id="@+id/grid_item_label"
      android:layout_width="match_parent"
      android:layout_height="fill_parent"
      android:background="@drawable/cell_shape"
      android:text="@string/_1"
      tools:ignore="InefficientWeight"
      android:textSize="12sp" &gt;
  &lt;/TextView&gt;
  
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>This is the shape for each TextView</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;shape xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools"&gt;
  &lt;solid android:color="#FFFFFF"/&gt;
  &lt;stroke android:width="1dp" android:color="#777777" /&gt;
  &lt;/shape&gt;
  </code></pre>
