Change linear layout top margin programmatically android

Question

i have two linear layouts in one frame layout.

Answer 1

I have set up margins directly using below code (I tried using LinearLayout.LayoutParams but is was not working for me)

LinearLayout layout = (LinearLayout)findViewById(R.id.yourrelative_layout);
LayoutParams params = new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT);
params.setMargins(3, 300, 3, 3); 
layout.setLayoutParams(params);

Only this here is to notice that LayoutParams should be imported for following package android.widget.RelativeLayout.LayoutParams unless you will hit error.
