Answer 1

You should try with

I assume FrameLayout creating this problem.

1. Use RelativeLayout instead of FrameLayout

2. Call ListView out side of RelativeLayout

Hope this helps .

Answer 2

Change the layout height containing your listview to match_parent .

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

and your listview height to match_parent

<ListView
    android:layout_below="@+id/head"
    android:id="@+id/list"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

Also make sure that the list items you supply to the listview is long enough for you to scroll. Hope this helps.

EDIT: I am not sure what BottomSheetLayout is about, but try set its layout height to match_parent as well.

<com.example.covite.chat_layout.BottomSheetLayout
    android:id="@+id/bottom_sheet"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="bottom"
    app:ft_container_gravity="center"
    app:ft_color="@color/primary">

OR if possible move your listview out of BottomSheetLayout , and make it a child for your RelativeLayout instead.
