title: Set a background color to a selected ListView Item in android
body: <p>I have a listview which displays several items. Now I want to scroll to some specific item (e.g. the 33th item). I know that this can be done via</p>
  
  <pre><code>myList.setSelection(32);
  </code></pre>
  
  <p>But on the UI the item doesn't receive any highlighting (because it is in touch mode?!). How can I apply a specific background color for this item? I tried</p>
  
  <pre><code>myList.getSelection().getSelectedView().setBackgroundColor(Color.Red);
  </code></pre>
  
  <p>but i get a NullPointerException because getSelectedView() returns null. Is there a way to achieve this highlighting? I have to notify the user somehow about which item is the "active" one...</p>
