Android判断touch事件点是否在view范围内的方法

private Rect mChangeImageBackgroundRect = null;private boolean isInChangeImageZone(View view, int x, int y) {    if (null == mChangeImageBackgroundRect) {      mChangeImageBackgroundRect = new Rect();    }    view.getDrawingRect(mChangeImageBackgroundRect);    int[] location = new int[2];    view.getLocationOnScreen(location);    mChangeImageBackgroundRect.left = location[0];    mChangeImageBackgroundRect.top = location[1];    mChangeImageBackgroundRect.right = mChangeImageBackgroundRect.right + location[0];    mChangeImageBackgroundRect.bottom = mChangeImageBackgroundRect.bottom + location[1];    return mChangeImageBackgroundRect.contains(x, y);}
