Change linear layout top margin programmatically android

Question

i have two linear layouts in one frame layout.

Answer 1

LayaoutParams usually create confusion while setting margin because of their parent layout... So this MarginLayoutParams is very useful which works with all layouts.

Java Code

MarginLayoutParams params = (MarginLayoutParams) view.getLayoutParams();
params.width = 200; //Ths value 200 is in px... Please convert in DP
params.leftMargin = 100; 
params.topMargin = 200;

Kotlin code

val params: MarginLayoutParams = view!!.layoutParams as MarginLayoutParams
params.width = 200 
params.leftMargin = 100 
params.topMargin = 200
