當滾動第二個時滾動RecyclerView

Question

我在我的主要活動2 RecyclerView s：一個是水平的，另一個是垂直的。我的問題是，當我在第二個回收站中向下滾動時，我想讓上方的回收站也滾動，但不是。它保持固定。

這是我的代碼：

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); 

Answer 1

您可以添加RecyclerView.OnScrollListener和手動滾動另一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); 
    } 
}); 

雖然我不明白你想什麼樣的影響來實現的，但至少你會得到這個概念。
