title: Android Display a list using ListView
body: <p>I am trying to display a list after clicking a button on Android.</p>
  
  <p>This is my code:</p>
  
  <pre><code>//Button after clicking should display a list
  final Button button4 = (Button) findViewById(R.id.widget30);
  button4.setOnClickListener(new View.OnClickListener() {
      public void onClick(View v) {
  
          Intent myIntent = new Intent(v.getContext(), TestListActivities.class);
          startActivity(myIntent);
  
      }
  
      public class TestListActivities extends Activity {
          String[] listItems = {"Game1", "Game2", 
                                "Game3", "Game4"};
          public ListView la;
  
          /** Called when the activity is first created. */
          @Override
          public void onCreate(Bundle savedInstanceState) {
              super.onCreate(savedInstanceState);
              setContentView(R.layout.main2);
              la=(ListView)findViewById(R.id.widget50);
              la.setAdapter(new ArrayAdapter&lt;String&gt;(this, 
              R.layout.main2, listItems));
          }
  }
  </code></pre>
  
  <p>My XML file is:</p>
  
  <pre><code>?xml version="1.0" encoding="utf-8"?
  AbsoluteLayout
  android:id="@+id/widget28"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  xmlns:android="http://schemas.android.com/apk/res/android"
  
  ListView
  android:id="@+id/widget50"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content" 
  
  AbsoluteLayoute
  </code></pre>
  
  <p>But when I click the button, the application is forced to close and it crashes.</p>
  
  <p>Manifest file
  
  
      </p>
  
  <pre><code>&lt;application android:icon="@drawable/icon" android:label="BAM! Pong" android:debuggable="true"&gt;
  
  
  &lt;activity android:name=".GUI" android:label="@string/app_name" android:screenOrientation="portrait"&gt;&lt;intent-filter&gt;&lt;action android:name="android.intent.action.MAIN"&gt;&lt;/action&gt;
  </code></pre>
