推荐答案

终于得到了答案。
在CoordinatorLayout中使用2 RecyclerView。

Finally got the answer. use 2 RecyclerView in CoordinatorLayout.

<android.support.design.widget.CoordinatorLayout
         android:id="@+id/mainBottomSheet"
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         android:background="@color/white">

         <android.support.v7.widget.RecyclerView
                  android:id="@+id/recyclerViewRight"
                  android:layout_width="match_parent"
                  android:layout_height="match_parent" />

         <android.support.v7.widget.RecyclerView
                  android:id="@+id/recyclerViewLeft"
                  android:layout_width="200dp"
                  android:layout_height="match_parent" />

</android.support.design.widget.CoordinatorLayout>

请注意，其中一个RecyclerView必须 match_parent 而另一个是任意大小的。建议将 match_parent 提供给第一个RecyclerView。

Note that one of the RecyclerView must be match_parent and the other one is of an arbitrary size. Advisable to provide match_parent to first RecyclerView.

这将导致两个RecyclerViews可滚动。

This will cause two RecyclerViews scrollable.

您可以使用下面的代码轻松地将RecyclerViews更改一半。

You can easily change the RecyclerViews by half using the code below.

 WindowManager windowManager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
            DisplayMetrics displayMetrics = new DisplayMetrics();
            windowManager.getDefaultDisplay().getMetrics(displayMetrics);
            deviceScreenUtilsWidth = displayMetrics.widthPixels;
recyclerViewLeft.getLayoutParams().width = deviceScreenUtilsWidth / 2;
