title: Android - Animate listview header
body: <p>I used header for my listview. this header should be shown at the certain time on top of the listview.
  I tried this piece of code: <code>listview.addHeaderView(header,null,true);</code>
  it works well, now I want to set an animation for this header, for example the header appears from right to left or something like that, how to do this? I can not find any helpful code.
  thanks.</p>
