You can't get the width from the xml. You can get it programmatically from your View:

@Override
protected void onSizeChanged(int width, int height, int oldw, int oldh) {

}

onSizeChanged is called whenever the size of the View changes (including the time the View is first constructed). Alternatively you can use getWidth() inside onDraw:

@Override
public void onDraw(Canvas canvas) {
  int width = this.getWidth();
}
