Private property currentScreen is not getting set because name collision:

    public void setCurrentScreen(int currentScreen) {

        if (!scroller.isFinished()) scroller.abortAnimation();
        currentScreen = Math.max(0, Math.min(currentScreen, getChildCount()));
        scrollTo(currentScreen * getWidth(), 0);
        Log.d("workspace", "setCurrentScreen: width is " + getWidth());
        invalidate();
    }

Change it to this:

   public void setCurrentScreen(int argCurrentScreen) {

        if (!scroller.isFinished()) scroller.abortAnimation();
        currentScreen = Math.max(0, Math.min(argCurrentScreen, getChildCount()));
        scrollTo(currentScreen * getWidth(), 0);
        Log.d("workspace", "setCurrentScreen: width is " + getWidth());
        invalidate();
    }

WorkspaceView crashes when tapping very fast one child window.

To reproduce tap the screen fast using at least two o three fingers, (first with the index finger, then with the second finger, then with the third finger).

I haven't been able to reproduce the issue with just 1 finger, and with two it is difficult to reproduce (at least on a fast smartphone). With three fingers is pretty easy though.

For example, when I am on the middle view and the device rotates, the view goes back to the default, leftmost view. This does not occur with the Android home screen.
