        val addressesLayoutManager = LinearLayoutManager(context)
        addressesLayoutManager.orientation = RecyclerView.VERTICAL
        addressesRv.layoutManager = addressesLayoutManager

addressesRv recycleView is not scrolling. I have this set in a bottomsheet dialog. It is just taking the 200dp height size and show only the items that fit, and I can not scroll through all items.

I have tried to take out the CardView , to remove the other recycle in the view, to wrap addressesRv inside a NestedScrollLayout, but neither one of the cases the scroll worked.

EDIT:

Answer 1

Because you are using multiple Recyclerview in same page and i think both recyclerView has LinearLayout manager with vertical orientation. I found your first recycler view height is wrapContent but second one is fixed. So here it has a change scrolling problem. So here you need nestedScrolview .

What nestedScrollView will do?:

Ans : It will help you to scroll both recyclerview.

More discussion about Problem: Suppose your first recyclerView has 10 element and these element cover full screen but your second recyclerView has also 10 element. Now both recyclerView not shwoing all element together. Because the cannot scroll without nestedScrollView

Code sample:

<androidx.cardview.widget.CardView
    android:id="@+id/cardViewInnerProductContainer"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="center"
    app:cardElevation="10dp"
    app:cardCornerRadius="10dp">

 <androidx.core.widget.NestedScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent">

    <androidx.constraintlayout.widget.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">
       // Your other code
  </androidx.constraintlayout.widget.ConstraintLayout>
  </androidx.core.widget.NestedScrollView>

Answer 2

If you put NestedScrollview, remove it.

And add this in your addressesRv recyclerview

android:layout_height="0dp"
app:layout_constraintBottom_toBottomOf="parent"

Answer 3

try this Place your constraint layout in CoOrdinator Layout

<android.support.design.widget.CoordinatorLayout 
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">

<androidx.constraintlayout.widget.ConstraintLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

</androidx.constraintlayout.widget.ConstraintLayout>

Answer 4

How do you add class in your RecyclerView? You must set LayoutManager in class. Example:

recyclerView = findViewById(R.id.recyclerView);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new StaggeredGridLayoutManager(1,StaggeredGridLayoutManager.HORIZONTAL));
