Set negative margin on View software

Question

I know how to programmatically set View fields using LinearLayout.LayoutParams and the setMargins(int, int, int, int) method, but how can I put a negative field in the view?

Answer 1

Access the layout options for the parent layout and modify them as you wish:

  ViewGroup.MarginLayoutParams params = (ViewGroup.MarginLayoutParams)view.getLayoutParams(); params.topMargin = ...; // etc // or params.setMargins(...); 

After changing the layout, call view.requestLayout() .

Answer 2

Using math seems to be a hoax to me enough.

  ViewGroup.MarginLayoutParams params = (ViewGroup.MarginLayoutParams)view.getLayoutParams(); params.topMargin = 100 - 200; // -100
