title: Position Buttons/Widgets in Android Studio without misplacing in different screen size
body: <p>I have already designed a user interface for my app in Photoshop. Then I added the user interface to Android Studio as a background image. Then I added some buttons in such a way that it is right over the the button in the user interface. Then, when I switched it to a different device, the button placement got messed up! Can anyone help me?<br>
  I tried using LinearLayout, but that didn't work!<br>
  So when someone uses my app they will click on the button, they will be only clicking the image. Please help!</p>
