I'm trying to implement features from the new Design Support Library to create a parallax scrolling toolbar which looks similar to the new material design WhatsApp profile pages. However, I can't get the overflow menu and back button to show in the top corners.
I have tried using the following methods to display the back button, but none of them works.
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
And overwriting the onCreateOptionsMenu method for the overflow menu also didn't work.
Does anyone know how to add these toolbar icons to a CollapsingToolbar from the Design Support Library? Below is my layout xml for the activity. Thanks!
<android.support.design.widget.CoordinatorLayout

The following enables the Navigation Button:
To get the Overflow Menu behavior you have to declare a menu.xml file with showAsAction:never applied to your menu items like:
And inflate it like:
