我有一个布局由父RecyclerView与子Recyclerview在里面

我知道，这是不是好放列表内的另一个列表中，但我必须这样我可以使用子列表的功能，如刷卡和拖放

Any help to achieve this?

推荐答案

我终于找到了一个解决方案。

I finally found a solution.

创建自定义LinearLayoutManager

Create Custom LinearLayoutManager

public class CustomLinearLayoutManager extends LinearLayoutManager {
public CustomLinearLayoutManager(Context context, int orientation, boolean reverseLayout) {
    super(context, orientation, reverseLayout);

}

// it will always pass false to RecyclerView when calling "canScrollVertically()" method.
@Override
public boolean canScrollVertically() {
    return false;
}
}

然后实例像这样的垂直滚动

Then instantiate it like this for vertical scrolling

CustomLinearLayoutManager customLayoutManager = new CustomLinearLayoutManager(getActivity(),LinearLayoutManager.VERTICAL,false);

最后设置自定义布局的回收视图布局管理器

Finally set the custom layout as layoutmanager of recycler view

recyclerView.setLayoutManager(customLayoutManager);
