title: How to target an element in a ListView with ShowcaseView in Android?
body: <p>I targeted the items in an action bar using <code>ShowcaseView</code>, but I can't target elements of a <code>ListView</code>! I tried that and it didn't work:</p>
  
  <pre><code>ShowcaseView sv = new ShowcaseView.Builder(this,true)
      .setTarget(new ViewTarget(lv.getChildAt(1).findViewById(R.id.heart)))
      // Here is where you supply the id of the action bar item you
      // want to display
      .setContentTitle("Heart")
      .setContentText("Check the venues of your city")
      .hideOnTouchOutside()
      .build();
  </code></pre>
