Question

I want to move what I have in my XML:

android:paddingLeft="12dp"
android:paddingRight="12dp"

to my code:

ListView listView = getListView();
listView.setPadding(12, 0, 12, 0);

The problem is that is appears the “setPadding” call only sets it by pixels, not dp. Anyone know how to properly set this in code?

Answer 1

you’ll have to do the conversion manually:

float scale = getResources().getDisplayMetrics().density;
// Convert the dps to pixels, based on density scale
int sizeInPx = (int) (sizeInDp*scale + 0.5f);
