BottomSheetCoordinatorLayout

implementation 'com.otaliastudios:bottomsheetcoordinatorlayout:1.0.4'

A handy CoordinatorLayout that works well when used in a bottom sheet, even with AppBarLayouts inside.

Having issues with android.support v28? Please try com.otaliastudios:bottomsheetcoordinatorlayout:1.1.0-RC1.

Usage

Just use BottomSheetCoordinatorLayout as the root view of your bottom sheet. It will be automatically given the right BottomSheetBehavior.

<com.otaliastudios.bottomsheetcoordinatorlayout.BottomSheetCoordinatorLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    
    <!-- AppBarLayout -->
    
    <!-- Everything else -->
    
</com.otaliastudios.bottomsheetcoordinatorlayout.BottomSheetCoordinatorLayout>

To get an instance of the behavior, use bscl.getBehavior(). As usual with behaviors, the returned value might be null if the view has not gone through a layout, so wait for that.

If you just want to set appropriate BottomSheetCallback, you can use bscl.setBottomSheetCallback(). Callbacks will be added to the sheet behavior as soon as it is available, so this can be called safely whenever you want. Same goes for other set() methods: they will apply the result to the behavior as soon as it is available.
