Answer 2

您必须覆盖 recyclerView 的 onScrollStateChanged，以便在滚动时可以检测视图是否移动并应用如下操作

setOnScrollListener(new AbsListView.OnScrollListener() {
    @Override public void onScrollStateChanged(AbsListView view, int scrollState) {
        switch (scrollState) {
            case SCROLL_STATE_IDLE: // The view is not scrolling.
            case SCROLL_STATE_TOUCH_SCROLL: // The user is scrolling using touch, and their finger is still on the screen
                Glide.with(...).resumeRequests(); // resume glide requests 
                break;
            case SCROLL_STATE_FLING: // The user had previously been scrolling using touch and had performed a fling
                Glide.with(...).pauseRequests(); // pause glide requests
                break;
        }
    }
});
