title: ListView onItemClick which implements Activity is not working
body: <p>I have a listview extends Activity and use custom adapter because I want icon and text on the listview.</p>
  
  <pre><code>String[] options = res.getStringArray(R.array.menu_title);
      TypedArray icons = res.obtainTypedArray(R.array.menu_icon);
      ImageAndTextAdapter iadapter = new ImageAndTextAdapter(ctx, R.layout.row, options, icons);
      MenuList.setAdapter(iadapter);
  </code></pre>
  
  <p>Then I use the setOnItemClickListener to make the listview clickable but fail.</p>
  
  <pre><code>MenuList.setOnItemClickListener(new ListView.OnItemClickListener() {
          public void onItemClick(AdapterView&lt;?&gt; arg0, View v, int position, long id) {
              Intent myIntent = new Intent(Menu.this, Revision.class);    
              Menu.this.startActivity(myIntent);
              }
      }); 
  </code></pre>
  
  <p>Here is the logcat:</p>
