Android - How to make an progressBar touching a bottom screen border

Question

I want a ProgressBar that is touching a bottom border of screen but with this piece of code, I am getting an little space between bar and screen border:

Answer 1

I have been struggling with this for a while now. My conclusion: There is no way to archieve this behaviour with XML for arbitrary screen sizes. On some screen sesolutions the progress bar will always be misplaced a little.

My simple solution: Set the Y of the progressbar programmatically to the Y of the super view/layout

protected void onLayout(boolean changed, int l, int t, int r, int b) {
    super.onLayout(changed, l, t, r, b);

    progressBar.setY(layout.getY() - progressBar.getHeight() / 2);
}

Works like a charm and for all screen sizes.
