Where idea is toolbar is collapsing when scrolled up (down?). 向上滚动(向下滚动)时工具栏崩溃的地方。 But there is a problem with where touch event is occurred.
但是发生触摸事件的地方存在问题。 If scroll initiated on any element except RecyclerView, everything works like a charm.
如果在除RecyclerView之外的任何元素上启动了滚动,则所有内容都将像超级按钮一样工作。 But if scroll touch is initiated on recyclerview, NestedScrollView starts scrolling without toolbar collapse or expand.
但是,如果在recyclerview上启动了滚动触摸,则NestedScrollView将开始滚动而不会折叠或展开工具栏。 RecyclerViews use custom layout manager, which wraps its content (each RecyclerView has few items).
RecyclerViews使用自定义布局管理器,该管理器包装其内容(每个RecyclerView都有几项)。 So here is a question.
所以这是一个问题。 How to tell RecyclerView to not to interfere with NestedScrollView's collapsing/expanding behavior?
如何告诉RecyclerView不要干扰NestedScrollView的折叠/展开行为?
i had the same problem but with NestedScrollView i used 我有同样的问题,但我使用的是NestedScrollView
android:nestedScrollingEnabled="false"
and the problem was gone, please try to add this and tell me if it works 并且问题消失了,请尝试添加它并告诉我是否可行
Good luck 祝好运
Try this: 尝试这个:
yourRecyclerView.addOnItemTouchListener(new RecyclerView.OnItemTouchListener() {
@Override
public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
return true; //Consume the touch event
}
...
});
