Error inflating class androidx.core.widget.NestedScrollView

Question

I am using NestedScrollView and I am getting error Error inflating class androidx.core.widget.NestedScrollView.I also tried android.support.v4.widget.NestedScrollView. But both don't work and getting error. In the nested scrollview there is linear layout and in linear layout, there is one imageview, one textview and recycler view. Is there any dependency that I have to add to use for NestedScrollView? Please help in resolving this issue. Thank you in advance.

Answer 1

Remove android:nestedScrollingEnabled="false" from NestedSrcollView and add it to RecyclerView, It should work fine.

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

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">
        <ImageView
            android:id="@+id/image"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />
        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:text="Group Members"
            android:textSize="30sp" />

        <androidx.recyclerview.widget.RecyclerView
            android:id="@+id/recycle_view"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:nestedScrollingEnabled="false" />

    </LinearLayout>
</androidx.core.widget.NestedScrollView>
