How Use 2 Recyclerview In Bottomsheetdialogfragment

my class extends from BottomSheetDialogFragment and in this layout use 2 recyclerViews. but always 1 recyclerView scrollable and other recyclerView not work.

Solution 1:

Finally got the answer. use 2 RecyclerView in CoordinatorLayout.

Two RecyclerViews 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>

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.

This will cause two RecyclerViews scrollable.

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

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

Solution 2:

I have a situation similar t this but in my case first recyclerview is in horizontal and the second one is in vertical. I couldn't scroll the second one directly. So I solved this issue by following way

<android.support.design.widget.CoordinatorLayout
      <android.support.v4.widget.NestedScrollView

      <android.support.v7.widget.RecyclerView
      <android.support.v7.widget.RecyclerView

and by setting the second recyclerview

     recycler.setNestedScrollingEnabled(false);
