How to expand navigation list in action bar?

Question

In android you could set a navigation list in action bar by passing spinner adapter and OnNavigationListener. the issue is that the navigation list dont fill most of the action

Answer 1

Maybe you can use ActionBar tab navigation and add icons to the tabs rather than the list navigation since the gmail's navigation looks more like tabs navigation.

Answer 2

You want to implement the getDropDownView method too. This lets you supply a different view for the dropdown list with the metrics and formatting you want.

Consider inflating the framework layouts android.R.layout.simple_spinner_item and android.R.layout.simple_spinner_dropdown_item for these situations. Use findViewById(android.R.id.text1) to get the TextView you should fill out in each one.
