android - BottomSheetBehavior 与两个 RecyclerView

Question

我在带有 BottomSheetBehavior 的 LinearLayout 中得到了两个 RecyclerView。当您单击第一个 RecyclerView(带有网格)内的项目时，RecyclerView 将设置为 Gone 并显示第二个 RecyclerView(带有列表)。当显示第二个 Recycler 时，您无法上下滑动 BottomSheet，而是即使在展开状态下列表也在滚动。如果 First Recycler 已启动，则一切正常。有没有办法让BottomSheet再次上下滑动？

<LinearLayout
        android:id="@+id/sliding_layout_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:focusable="true"
        android:focusableInTouchMode="true"
        android:orientation="vertical"
        app:behavior_hideable="false"
        app:behavior_peekHeight="400dp"
        app:layout_behavior="@string/bottomSheetBehavior">

        <android.support.v7.widget.RecyclerView 
           android:id="@+id/grid"
           android:layout_width="match_parent"
           android:layout_height="match_parent"
           android:layout_marginEnd="@dimen/activity_horizontal_margin"
           android:layout_marginStart="@dimen/activity_horizontal_margin"
           android:background="@color/white"
           android:clickable="true"
           android:scrollbars="none" />

        <android.support.v7.widget.RecyclerView 
           android:id="@+id/list"
           android:layout_width="match_parent"
           android:layout_height="match_parent"
           android:layout_marginEnd="@dimen/activity_horizontal_margin"
           android:layout_marginStart="@dimen/activity_horizontal_margin"
           android:background="@color/white"
           android:clickable="true"
           android:scrollbars="none" />
</LinearLayout>

网格适配器:

   @Override
   public void onBindViewHolder(ViewHolder holder, int position) {

    String categorieName = mCategories.get(position);
    final CategoryFilterEvent event = new   CategoryFilterEvent(categorieName);
    holder.grid_item_label.setText(categorieName);

    holder.itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            EventBus.getDefault().post(event);
        }
    });
}

主要 Activity :

 @Override
 public void onCreate(Bundle savedInstanceState) {

    linearLayoutManager = new LinearLayoutManager(this);
    listAdapter = new ListAdapter(this, mList);
    recyList.setAdapter(listAdapter);
    recyList.setLayoutManager(linearLayoutManager);

    gridLayoutManager = new GridLayoutManager(this, 3);
    gridAdapter = new GridAdapter(this, new ArrayList<String>());
    recyGrid.setAdapter(gridAdapter);
    recyGrid.setLayoutManager(gridLayoutManager);
}

public void onEventMainThread(CategoryFilterEvent event) {
    recyGrid.setVisibilty(GONE);
    recyList.setVisiblity(VISIBLE);
}

您是否在 BottomSheetDialogFragment 中有两个 recyclerView(第一个 - 水平，第二个 - 垂直)和第二个不可滚动的 recyclerView？在为它设置适配器后，只需将其添加到第一个回收器:

ViewCompat.setNestedScrollingEnabled(recyclerView1, false)
