GridLayout change only one specific element?

Question

I have GridLayout 7x7, is it possible to change content only of cell (3,4) and I want to do it dynamically. Example: I have 7x7 grid of buttons and want to change button on position (3,4) to TextView.

EDIT: Also, is it possible to set zero padding around child?

Thanks!

Answer 1

In GridView you cant access elements specific by coordinates (3,4). The elements are numbered like in 2D arrays. So your (3,4) element will have (7*3+4)-1 index. And you can access it by.

ViewGroup gridChild = (ViewGroup) mGridView.getChildAt(24);

EDIT: Set padding to zero.

gridChild.setPadding(0,0,0,0);
