Usage

From source file:Main.java

public static void invalidateGlobalRegion(View view, RectF childBounds) {
    //childBounds.offset(view.getTranslationX(), view.getTranslationY());
    if (DEBUG_INVALIDATE)
        Log.v(TAG, "-------------");
    while (view.getParent() != null && view.getParent() instanceof View) {
        view = (View) view.getParent();
        view.getMatrix().mapRect(childBounds);
        view.invalidate((int) Math.floor(childBounds.left), (int) Math.floor(childBounds.top),
                (int) Math.ceil(childBounds.right), (int) Math.ceil(childBounds.bottom));
        if (DEBUG_INVALIDATE) {
            Log.v(TAG,//  www  .  j  a va2 s  .co  m
                    "INVALIDATE(" + (int) Math.floor(childBounds.left) + "," + (int) Math.floor(childBounds.top)
