You can also use Rect.intersect() to find overlapping views.

    int[] firstPosition = new int[2];
    int[] secondPosition = new int[2];

    firstView.getLocationOnScreen(firstPosition);
    secondView.getLocationOnScreen(secondPosition);

    // Rect constructor parameters: left, top, right, bottom
    Rect rectFirstView = new Rect(firstPosition[0], firstPosition[1],
            firstPosition[0] + firstView.getMeasuredWidth(), firstPosition[1] + firstView.getMeasuredHeight());
    Rect rectSecondView = new Rect(secondPosition[0], secondPosition[1],
            secondPosition[0] + secondView.getMeasuredWidth(), secondPosition[1] + secondView.getMeasuredHeight());
    return rectFirstView.intersect(rectSecondView);
