I want to programmatically set in my layout size. And this layout size get from dimen folder. but the problem is when I get the value from dimen folder, It gets displayed in a normal resolution screen perfectly but when it runs in a high display resolution it doesn't run perfectly

Yes I solved my screen resolution problem. When you get value from dimen folder it get in Pixel format. And Pixel size depends on your device resolution Not device size. So you need create screen size and screen resolution based dimen folder. As like:

In this folder categorized in different screen size and different screen resolution.
