do you really need the `NestedScrollView` ? It could be your problem , at least I had the same... Is it possible to remove it? — Ilya Maier, Apr 16 '20 at 18:39
else, just try this in your `RecyclerView` : `app:layout_behavior="@string/appbar_scrolling_view_behavior"` — Ilya Maier, Apr 16 '20 at 18:40
Can you post the picture to get a visual representation of your UI? Can you tell us whether you are scrolling on the Recyclerview items or on the image? — Srikar Reddy, Apr 16 '20 at 19:36

You could try removing your NestedScrollView as it overlaps with RecyclerView and that's why it#s not scrolling.

Else you could insert that code in your RecyclerCode:

 app:layout_behavior="@string/appbar_scrolling_view_behavior"

could you share a picture of how it looks like? and maybe your RecyclerView initialization code @user113428 – Ilya Maier Apr 16 '20 at 18:57

I sloved it. this is Cover RecyclerView

    <!--menu-->
<androidx.drawerlayout.widget.DrawerLayout
    android:layout_width="match_parent"
    tools:openDrawer="end"
    android:layout_height="match_parent"
    android:id="@+id/drawer_layout">

So I replace it To :

<!--menu-->
<androidx.drawerlayout.widget.DrawerLayout
    android:layout_width="match_parent"
    tools:openDrawer="end"
    android:layout_height="match_parent"
    android:id="@+id/drawer_layout">

    <!--    RecyclerView-->

    <androidx.recyclerview.widget.RecyclerView
        android:id="@+id/recycler"
        android:layout_marginTop="250dp"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
    </androidx.recyclerview.widget.RecyclerView>

Please add android:fillViewport="true" in NestedScrollView Tag...
then add android:nestedScrollingEnabled="true" in RecyclerView Tag...

<androidx.core.widget.NestedScrollView
        android:layout_width="match_parent"
        android:layout_marginTop="250dp"
        android:layout_height="match_parent"
        android:fillViewport="true">
        <androidx.recyclerview.widget.RecyclerView
            android:id="@+id/recycler"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:nestedScrollingEnabled="true">
        </androidx.recyclerview.widget.RecyclerView>
    </androidx.core.widget.NestedScrollView>
