BottomSheet : The view is not a child of CoordinatorLayout

Question

I've checked other posts having this problem and they said use <merge> instead of <include> but when i use <merge> it shows red in my fragment.xml file, there is no such tag. How can i solve this error?

In my fragment.xml :

<androidx.coordinatorlayout.widget.CoordinatorLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <include layout="@layout/product_variation_bottom_sheet" />

</androidx.coordinatorlayout.widget.CoordinatorLayout>

In my Fragment.kt :

var view = inflater.inflate(R.layout.bottom_sheet, container, false)
bottomSheetBehavior = BottomSheetBehavior.from(view.findViewById(R.id.bottomSheet))

In my bottom_sheet.xml :

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/productVariationBottomSheet"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:layout_behavior="@string/bottom_sheet_behavior"
    app:behavior_peekHeight="0sp"
    app:behavior_hideable="true"
    android:background="#00000000"
    xmlns:app="http://schemas.android.com/apk/res-auto">
    //some other views
</LinearLayout>

Answer 1

You must have parent layout as CoordinatorLayout. You put the CoordinatorLayout where you place the container. The container must be under the CoordinatorLayout.

Answer 2

Couldn't find any solution to solve it, so i stopped using <include> and just put all the BottomSheet's layout code into my fragment.xml altogether. Then access the BottomSheet layout directly using viewBinding . This way, it works. Any other solution that works, feel free to share your solution.
