Question

我在我的主要活动中有RecyclerView个：一个是水平的，另一个是垂直的。我的问题是，当我向下滚动第二个回收器时，我希望上部回收器也能滚动，但事实并非如此。它保持不变。

这是我的代码：

recyclerView = (RecyclerView) findViewById(R.id.recyclerview1);
recylerViewLayoutManager = new LinearLayoutManager(context,LinearLayoutManager.HORIZONTAL,false);
recyclerView.setLayoutManager(recylerViewLayoutManager);
recyclerViewAdapter = new RecyclerViewAdapter(MainActivity.this, subjects,images);
recyclerView.setAdapter(recyclerViewAdapter);


MainGridRecView = (RecyclerView) findViewById(R.id.maingridrc);
MainGridRecViewLayoutManager = new GridLayoutManager(context,2);
MainGridRecView.setLayoutManager(MainGridRecViewLayoutManager);
MainGridRecViewAdapter = new MainGridRecyclerViewAdapter(MainActivity.this, subjects,images);
MainGridRecView.setAdapter(MainGridRecViewAdapter);

您可以添加RecyclerView.OnScrollListener并手动滚动另一个RecyclerView：

recyclerView1.addOnScrollListener(new RecyclerView.OnScrollListener() {
    @Override
    public void onScrolled(final RecyclerView recyclerView, final int dx, final int dy) {
        recyclerView2.setScrollX(dx);
        recyclerView2.setScrollY(dy);
    }
});

虽然我没有达到你想要达到的效果，但至少你会得到这个概念。

滚动第二个时滚动RecyclerView
