Child view is cut off when `expandedOffset` is set on BottomSheetBehavior

Description:

When I add a RecyclerView to that FragmentContainerView, the bottom of it is cut off (doesn’t let me scroll to the end) by the same amount as I set as the behavior_expandedOffset.

Expected behavior:

I would expect all content to be scrollable.

Source code:

    <androidx.constraintlayout.widget.ConstraintLayout
        style="@style/ONX.Widget.BottomSheet.Light"
        android:id="@+id/query_bottomsheet"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="com.google.android.material.bottomsheet.BottomSheetBehavior">

        <com.onxmaps.onxmaps.customviews.bottomsheetheader.BottomSheetHeader
            android:id="@+id/map_query_header"
            android:layout_height="wrap_content"
            android:layout_width="0dp"
            app:layout_constraintTop_toTopOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintEnd_toEndOf="parent"/>

        <androidx.fragment.app.FragmentContainerView
            android:id="@+id/map_query_container"
            android:name="com.onxmaps.onxmaps.bottomsheet.BottomSheetLoadingFragment"
            android:layout_width="0dp"
            android:layout_height="0dp"
            app:layout_constraintTop_toBottomOf="@id/map_query_header"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintBottom_toBottomOf="parent"/>

    </androidx.constraintlayout.widget.ConstraintLayout>

with the following style:

    <style name="ONX.Widget.BottomSheet" parent="Widget.MaterialComponents.BottomSheet">
        <item name="android:paddingTop">@dimen/bottomsheet_padding_top</item>
        <item name="behavior_halfExpandedRatio">@dimen/bottomsheet_halfratio</item>
        <item name="behavior_fitToContents">false</item>
        <item name="behavior_hideable">true</item>
        <item name="shapeAppearance">@null</item>
        <item name="behavior_expandedOffset">150</item>

Android API version: 28

Material Library version: Material Android Library version you are using here (e.g., 1.1.0-alpha07)

implementation 'com.google.android.material:material:1.1.0'

implementation 'androidx.constraintlayout:constraintlayout:2.0.0-beta3'

implementation 'androidx.appcompat:appcompat:1.0.2'

I also tried material:1.2.0-alpha06 and constraintlayout:2.0.0-beta5

I was facing the same issue, and I replaced ConstraintLayout to LinearLayout… Magically everything starts working… I know it is super weird, but this is the only fix which resolved the issue…

same as @TakeoffAndroid, replace constraintLayout to LinearLayout “solved” the problem
