drawer indicator with ActionBar compat

I have an application that is using the ActionBarCompat library as well as the NavigationDrawer support library.

I have managed to set up ActionBarDrawerToggle to get the drawer indicator on ICS+ devices, but it doesn't automatically enable it on Gingerbread devices with the ActionbarCompat.

Does anybody know of a way, or what changes I would need to make to the ActionBarCompat to enable the drawer indicator for those devices?

Solution

  • I managed to solve this by manually adding an image view as the first item in the ActionBarCompat, by modifying the construction of the compatibility bar in the library itself.

    I believe the particular class in question is ActionBarHelperBase.java

    Once this is in place, I animate it (similar to the real one) by translating the image in drawer open/close callbacks.

    I say "similar" because the difference with my "hack" is that it will not animate until the drawer has finished opening/closing whereas the real one opens/closes WHILE the drawer is opening closing. it is a minor difference and doesn't/shouldn't cause too much issue.

    There is not need to do conditional checking within the class because the code is only ever called for "compatible" ActionBars (i.e. pre-honeycomb).
