title: How can I launch an activity using ListView instead of ordinary buttons? Android / Eclipse
body: <p>I looked up tutorials on how to launch activities from list view instead of regular buttons and I think I'm right on this but for some reason my emulator isn't launching the second activity it just shows that I've pressed the button but nothing happens.</p>
  
  <p>Here's a copy of my MainActivityThree.java...</p>
  
  <pre><code>package testing.android.application.three;

  public class MainActivityThree extends ListActivity {
  
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
     //setContentView(R.layout.activity_main_activity_three);
      String[] names = new String[]{"Test 5","Test 10","Test 15","Test 20","Test 25","Test 30"};
      setListAdapter(new ArrayAdapter&lt;String&gt;(this,android.R.layout.simple_list_item_1,names));
  
  }
  
  private static final int Test 5 = 0;
  private static final int Test 10 = 1;
  
  @Override
  protected void onListItemClick(ListView l, View v, int position, long id) {
  
      Class &lt;?&gt; MainActivityNext = null;
      switch(position) {
          case Test 5 :
              MainActivityNext = MainActivityNext.class;
              break;
         //keep the same logic for other cases
      }
