title: What is the default drawable for pressing a list item
body: <p>When the user presses a ListView item (android:state_pressed="true") it flashes a shade of yellow (or you can press and hold).</p>
  
  <p>What drawable is this?  I've created my own selector because I want my own ListView item color , but I lose the pressed color.</p>
  
  <p>There's an Android doc about skinning buttons that references #ffff0000, but this produces red.</p>
  
  <p>Does anyone know what it is and how to reference it?</p>
