Bottom sheet margin top not working correctly - Android

Question

I am working with bottom sheet and it is working great if I dont add margin top.

I want the bottom sheet to fill the screen when pulled up but it also goes behind the Action Bar.
To solve this, I added margin top to the bottom sheet equivalent to the height of action bar, it works great until bottom bar is back to bottom.

<RelativeLayout
    android:id="@+id/rl_bottom_sheet"
    android:layout_width="match_parent"
    android:layout_height="280dp"
    android:margin_top="60dp"
    app:behavior_peekHeight="80dp"
    app:behavior_hideable="false"
    app:layout_behavior="@string/bottom_sheet_behavior"
    android:background="@drawable/ic_camera">

When bottom sheet is slided down, margin is no more there and view above the screen becomes equal to peekHeight + marginTop

Answer 1

I can suggest you to change the root layout - from CoordinatorLayout to any other (Relative/Linear and so on). And after that you can add your CoordinatorLayout in your new root ViewGroup with desired marginTop.

android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="80dp"
