阅读更多关于 Using support action bar home enabled

问题 I've just modified our code to use the new SupportActionBar provided in the v7-appcompat library but when running the code on a Jellybean phone (presumably the same problem exists for Honeycomb and Ice Cream Sandwich) the home button doesn't ever seem to be activated. Calling getSupportActionBar().setHomeButtonEnabled(true); doesn't seem to do what it says but works for Gingerbread phones.
