title: How to make a widget on the top / over others in Andorid?
body: <p>Is it possible to put a widget on the top of the others ?</p>
  
  <p>The real purpose of this is making a button visible when the softInputKeyboard appears. This button must always be just over the softKeyboard, wherever the scrollBar is.</p>
  
  <p>So maybe there is an other solution to reach the goal, ask for precision, Thanks.</p>
