title: android layout at different screen sizes
body: <p>trying to get my head around screen sizes so my app looks the same on different devices.</p>
  
  <p>I have two devices a galaxy s3 and a galaxy tab 8. both have the same resolution screen 720 x 1280 but the s3 is 4.7 inches while the tab is 8 inches</p>
  
  <p>When I do a linear layout I set padding to 130 at the top so that the first textview is 130 pixels from the top so the image on the background is not obscured.</p>
  
  <p>This is fine on the s3 but when I load it on the tab the padding needs changing to 190 pixels for it to look the same. </p>
  
  <p>I cant get my head round if the height of the screen resolution is the same (1280) on both devices why do i need larger padding on the screen</p>
  
  <p>is there a way of working out how to make the textview appear on the same location on both devices</p>
  
  <p>Any help appreciated</p>
