“Note that you cannot call the method before view layouts.” The above text is the clue. Dialogs have a listener that is fired once the dialog is shown. The dialog cannot be shown if it isn’t laid out. So, in the onCreateDialog() of your modal bottom sheet (BottomSheetFragment), just before returning the dialog (or anywhere, … Read more
I found the answer here: https://stackoverflow.com/a/30632980/875249 To avoid the link its pretty straightforward: mNavigationView.setItemIconTintList(null); This disables all state based tinting, but you can also specify your own list too.

All you need to do is define a group with an unique ID, I have checked the implementation if group has different id’s it will create a divider. Example menu, creating the separator: <menu xmlns:android=”http://schemas.android.com/apk/res/android” xmlns:app=”http://schemas.android.com/apk/res-auto” xmlns:tools=”http://schemas.android.com/tools” tools:context=”.MainActivity”> <group android:id=”@+id/grp1″ android:checkableBehavior=”single” > <item android:id=”@+id/navigation_item_1″ android:checked=”true” android:icon=”@drawable/ic_home” android:title=”@string/navigation_item_1″ /> </group> <group android:id=”@+id/grp2″ android:checkableBehavior=”single” > <item android:id=”@+id/navigation_item_2″ … Read more

This will provide the ASCII tree as shown in the update to the question, and it should help you identify what is … Read more
Version 23.1.0 switches NavigationView to using a RecyclerView (rather than the previous ListView) and the header is added as one of those elements. This means it is not instantly available to call findViewById() – a layout pass is needed before it is attached to the NavigationView. For version 23.1.1 of the Support Library, you can … Read more
