FloatingActionButton with BottomNavigationView

Question

I cant position my FAB. It should be bottom right, but on top of the BottonNavigationView.

1) Can i achieve this without RelativeLayout inside coordinateLayout?

Answer 1

A quick search to FloatingActionButton.Behavior tells us the following thing.

@Override
public void onAttachedToLayoutParams(@NonNull CoordinatorLayout.LayoutParams lp) {
    if (lp.dodgeInsetEdges == Gravity.NO_GRAVITY) {
        // If the developer hasn't set dodgeInsetEdges, lets set it to BOTTOM so that
        // we dodge any Snackbars
        lp.dodgeInsetEdges = Gravity.BOTTOM;
    }
}

Since BottomNavigationView also resides at the bottom of the layout. Add following element to your BottomNavigationView and CoordinatorLayout will handle the inset and dodging for you automatically.

app:layout_insetEdge="bottom"
