Change linear layout top margin programmatically android

Question

i have two linear layouts in one frame layout.

Answer 1

This updates the top margin without the need to update the other margin values.

LinearLayout layout = (LinearLayout) findViewById(R.id.your_linear_layout);
LinearLayout.LayoutParams layoutParams = (LinearLayout.LayoutParams) layout.getLayoutParams();
layoutParams.topMargin = 200;
layout.setLayoutParams(layoutParams);
