title: Put on the right the indicator of an ExpandableListView in Android
body: <p><img src="https://i.stack.imgur.com/7afYY.png" alt="example"></p>
  
  <p>I have to move the indicator from the left to the right (because of the plane image). I couldn't succeed also because the expandableviewlist is inside a fragment and not inside a whole activity. Any idea? Thanks!</p>
