title: ’android:paddingRight’ working with ‘android:drawableRight’
body: <p>In a EditText,I put a pic in the Rightside of the EditText,
  and I use FrameLayout to add a textview showing the remain input count of the Edittext(as show in p1).
  <img src="https://i.stack.imgur.com/YKeaH.png" alt="p1"></p>
  
  <p>But when the input is too long,it will overlay with the textview,to avoid this,I want use android:paddingRight to keep the input characters stay left,but the result is like p2<img src="https://i.stack.imgur.com/n6LSX.png" alt="p2"></p>
  
  <p>how to make the drawable icon stay at right and just the input characters ,like p3?<img src="https://i.stack.imgur.com/wfRlL.png" alt="enter image description here">
  Thank you.</p>
