title: How to move a Textview dynamically on the screen? (framelayout)
body: <p>I have a app that shows the camera view on the screen on a FrameLayout. The screen is in fixed LandScape mode.</p>
  
  <p>I need to write a textView with dynamically determined coordinates of the screen. The coordinates are determined in percentages, for example :</p>
  
  <p>write the textview on the coorinates x=80% of the screen &amp; y=20% of the screen. write the textview on the coorinates x=35% of the screen &amp; y=55% of the screen.</p>
  
  <p>how to do it? i already have the percentages, i only need to know how to use them to write the textview on the desired position of the frameLayout</p>
  
  <p>code examples are welcome</p>
  
  <p>i tried with this but doesn't works, the textview isn't moved:</p>
  
  <pre><code>TextView poi..... etc etc
  poi.setLayoutParams(new LayoutParams((int)(w*(xCoordPercent/100)), h/2));
  </code></pre>
  
  <p>thanks</p>
