How to create a square button that adjusts to list item height?

Question

In a Listview I want create a square button that is as wide as the list item is heigh.I don't want to set fixed width and height as it should work for different resolutions. Is is possible?

Answer 1

In your layout xml file tell it to fill it's parent:

<Button android:layout_width="fill_parent" .... ></Button>

Or if you are using the API I think you should be able to use setLayoutParams:

myButton.setLayoutParams(new AbsListView.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); 

Answer 2

Use density independent pixel (dip) which is a virtual pixel unit to express layout dimensions or position in a density-independent way.
