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);
}

其中view是要判断的view ,x,y是Down X, Down Y

希望本文所述对大家Android程序设计有所帮助。
