@liufei96 @github-of-daibing 试下PhotoViewAttacher.setAllowParentInterceptOnEdge(false);

    /**
     * Here we decide whether to let the ImageView's parent to start taking
     * over the touch event.
     *
     * First we check whether this function is enabled. We never want the
     * parent to take over if we're scaling. We then check the edge we're
     * on, and the direction of the scroll (i.e. if we're pulling against
     * the edge, aka 'overscrolling', let the parent take over).
