Make RelativeLayout to fit all screen size

I'm trying to modify my Relative Layout to fit all the screen size. I understood that my problem was that I was manually setting the margin for every single element on the screen, because it was easier to set on the editor in Android Studio, but obviously, as soon as I tried the app on another device the elements were in a mess. Now, I modified it by using the "match_parent" and wrap_content commands to make it more flexibly, and this is the result when I try it on a Pixel C: enter image description here

The problem is when I change device, because for example if I try It on a Galaxy Tab this is the result: enter image description here

This is the code:

Solution

  • You can use the SDP to set the size of controls or text for different devices.

    enter image description here

    An android SDK that provides a new size unit - sdp (scalable dp). This size unit scales with the screen size. It can help Android developers with supporting multiple screens.
