Custom background color for selected item with "activatedBackgroundIndicator" Navigation Drawer

This question has been asked a lot on SO, and I have referenced all the answers. I am still left with the default Holo blue background for selected items on my navigation drawer. I am new to Java and I am confused about the "context" part of `.setAdapter()`. My project is a single Activity with multiple fragments swapped using the nav drawer. Here is my adapter: ``` mDrawerListView.setAdapter(new ArrayAdapter<String>( // First parameter - Context getActionBar().getThemedContext(), // Second parameter - Layout for the row R.layout.fragment_navigation_drawer_list_item, // Third parameter - ID of the TextView to which the data is written android.R.id.text1, // Forth - the Array of data new String[]{ getString(R.string.title_section1), getString(R.string.title_section2), getString(R.string.title_section3), getString(R.string.title_section4), })); mDrawerListView.setItemChecked(mCurrentSelectedPosition, true); ``` The context here comes from the "pre-cooked" navigation drawer in Android Studio. I thought this would be the answer Navigation Drawer item background colour for selected item. So I changed my context to `getActivity().getBaseContext(),`, but that didn't change anything. My theme (`styles.xml`): ``` <resources> <style name="AppBaseTheme" parent="@style/Theme.AppCompat.Light.DarkActionBar"> <!-- API 14 theme customizations can go here. --> <item name="android:actionBarStyle">@style/ActionBar</item> </style> <!-- Navigation Drawer styling --> <style name="NavDrawerItemSelected" parent="AppBaseTheme"> <item name="android:activatedBackgroundIndicator">@drawable/activated_background</item> </style> </resources> ``` `activated_background` in 'drawables' dir: ``` <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_activated="true" android:drawable="@color/green" /> <item android:state_selected="true" android:drawable="@color/green" /> <item android:state_pressed="true" android:drawable="@color/green" /> <item android:state_checked="true" android:drawable="@color/green" /> <item android:drawable="@android:color/transparent" /> </selector> ``` I don't know which of those above states is supposed to be used, so I added all of them I could find. Finally, when an item is selected `mDrawerListView.setItemChecked(position, true);` is called. Everything works, except for the custom theme styling. (min API = 11, testing on API 17 AVD)
