title: setMarginEnd is not working for RTL languages
body: <p>I have a custom view (<code>TextView</code>). When the user clicks on the screen, the custom view will move based on touch (X position). For that I'm calling <code>setMarginLeft</code> on the custom view dynamically in LTR languages. If the default orientation is RTL then I'm calling <code>setMarginEnd</code> on the custom view. In LTR it is working fine but in RTL is not working. I think <code>setMarginEnd</code> is not working in RTL.</p>
  
  <p>Thanks in advance.</p>
