Android button tap slop region

Question

In android, when I press and hold in a button, then move the pointer outside the button, the button un-highlights. But I have to move it significantly outside the button; just a few pixels isn't enough. And the slop seems to be wider than it is tall. What are the values of the slop dimensions? Where can I find them?

Answer 1

The values, by experimentation, appear to be SLOP_X = 24 and SLOP_Y = 0. Not real sure about the Y slop; scroll sensitivity is involved and it gets a little weird.
