how to clear error this

CodePudding user response：

you should use scrollview like this sample

<androidx.core.widget.NestedScrollView
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
    
    <androidx.appcompat.widget.LinearLayoutCompat
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">
        
        <TextView />

        <TextView />

        <TextView />
        
    </androidx.appcompat.widget.LinearLayoutCompat>
    
</androidx.core.widget.NestedScrollView>

Not Like this

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

    <androidx.appcompat.widget.LinearLayoutCompat
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

    </androidx.appcompat.widget.LinearLayoutCompat>

    <TextView />

    <TextView />

    <TextView />

</androidx.core.widget.NestedScrollView>
