                android:layout_marginTop="20dp"
                android:clipToPadding="false"
                android:paddingHorizontal="10dp"
                android:paddingBottom="120dp"

  <androidx.recyclerview.widget.RecyclerView
                android:id="@+id/rv_dynamic_inner_reporting"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_marginTop="10dp"
                android:orientation="vertical"
                android:paddingBottom="10dp"
                app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager"
                app:layout_constraintTop_toBottomOf="@id/mtv_date_dynamic"
                tools:listitem="@layout/item_inner_reporting" />

The inner recycler view is not scrolling I have tried many solutions, non helped me, how can I make the inner recycler view scroll vertically, they both scroll vertically.

Solution

Issue is solved by showing only four items in the inner Recycler View, and enabling nestedScrollView = true, also handling OnTouch Events for the parent Recycler View.
