I tried the following solution: ActionBarSherlock & HoloEverywhere - Forcing Overflow? but it does not work because absForceOverflow does not exist. Was it removed in the newest version or something?

问题 I know it's not possible using the native API. Is there a workaround to implement that kind of view? 回答1: The previously posted answer is OK, generally speaking.

ActionBar actionBar = getActionBar(); actionBar.setDisplayShowTitleEnabled(true); actionBar.setTitle("Canteen Home"); actionBar.setHomeButtonEnabled(true); actionBar.setIcon(R.drawable.back); 回答1: To have a centered title in ABS (if you want to have this in the default ActionBar , just remove the "support" in the method names), you could just

问题 How (if possible) could I set a custom font in a ActionBar title text(only - not the tab text) with a font in my assets folder? I don't want to use the android:logo option. 回答1: I agree that this isn't completely supported, but here's what I did.

All of my activities inherit from a single activity, which has this code in
