title: How to set Single Choice Items inside AlertDialog?
body: <p>I haven't been able to set a Single Choice list, or a Multiple Choice List inside an AlertDialog.</p>
  
  <p>I tried following the examples but I only get a Dialog with a Title, the Ok and Cancel buttons, and no list, and NO message (which I set!).</p>
  
  <p>Here is the code:</p>
  
  <pre><code>    protected Dialog onCreateDialog(int id) {
      switch (id) {
      case DIALOG_DELETE_CITY:
          CharSequence[] array = {"Red", "Blue", "Yellow"}; 
          return new AlertDialog.Builder(ShowPypData.this)
              .setTitle(R.string.city_actions_delete_label)
              .setMessage(R.string.city_actions_delete_select_label)
              .setSingleChoiceItems(array, -1, new DialogInterface.OnClickListener() {
  
                      @Override
                      public void onClick(DialogInterface dialog, int which) {
                          // TODO Auto-generated method stub
  
                      }
                  })
              .setPositiveButton(android.R.string.ok, new DialogInterface.OnClickListener() {
  
                  @Override
                  public void onClick(DialogInterface dialog, int which) {
                      // TODO Auto-generated method stub
  
                  }
  
              })
              .setNegativeButton(android.R.string.cancel, new DialogInterface.OnClickListener() {
  
                  @Override
                  public void onClick(DialogInterface dialog, int which) {
                      dialog.dismiss();
  
                  }
              }).create();
      default:
          return null;
      }
  
  }
  </code></pre>
  
  <p>The weird thing is that if I comment the setSingleChoiceItems part, I can see the message  on the dialog.</p>
