Recycler视图内部的Recycler视图不滚动

问题描述

另一个Recycler View内有一个Recycler View，两者都需要垂直滚动. 外部回收者"视图可以正确滚动，但不能内部回收者"视图滚动.

There is a Recycler View inside the other Recycler View.Both needs to scroll vertically. Outer Recycler view is scrolling properly but inner recycler view is not.

这是代码:

LinearLayoutManager mLayoutManager = new LinearLayoutManager(ViewActivity.this);
outerRecyclerView.setLayoutManager(mLayoutManager);
ViewAdapter adapter = new ViewAdapter(ViewActivity.this);
outerRecyclerView.setAdapter(adapter);

ViewAdapter如下:

ViewAdapter is as follows:

public void onBindViewHolder(ViewAdapter.ViewViewHolder holder, int position)
{
  //RECYCLER VIEW
  //TODO: Inner Recycler view scroll movement
  LinearLayoutManager mLayoutManager = new LinearLayoutManager(context);
  holder.protocolRecyclerView.setLayoutManager(mLayoutManager);
  ViewProtocolAdapter adapter = new ViewProtocolAdapter(context);
  holder.protocolRecyclerView.setAdapter(adapter);
}

我已经在两个回收站视图上尝试了以下方法，但无法解决问题

I have tried the following on both recycler views but could not solve the problem

recyclerView.addOnItemTouchListener(new RecyclerView.OnItemTouchListener() {
       @Override
       public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
           if(rv.getChildCount() > 0) {
               View childView = rv.findChildViewUnder(e.getX(), e.getY());
               if(childView ==listView) {
                   int action = e.getAction();
                   switch (action) {
                       case MotionEvent.ACTION_DOWN:
                           rv.requestDisallowInterceptTouchEvent(true);
                   }
               }
           }

           return false;
       }

       @Override
       public void onTouchEvent(RecyclerView rv, MotionEvent e) {

       }

       @Override
       public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {

       }
   });

也尝试过这个:

outerRecyclerView.setNestedScrollingEnabled(true);//Does not make any difference
innerRecyclerView.setNestedScrollingEnabled(true);//Recycler View start scrolling but very slowly and sometimes scrolls the outer one.

推荐答案

RecyclerView.OnItemTouchListener mScrollTouchListener = new RecyclerView.OnItemTouchListener() {
@Override
public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
    int action = e.getAction();
    switch (action) {
        case MotionEvent.ACTION_MOVE:
            rv.getParent().requestDisallowInterceptTouchEvent(true);
            break;
    }
    return false;
}

@Override
public void onTouchEvent(RecyclerView rv, MotionEvent e) {

}

@Override
public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {

}
};

innerrecyclerView.addOnItemTouchListener(mScrollTouchListener);
