问题 I have an activity with many fragments that uses action bar and navigation drawer. It has "home as up" enabled. I have implemented proper logic that only top level fragments show action bar drawer toggle icon, other fragments show up arrow. I achieved this by: mDrawerToggle.setDrawerIndicatorEnabled(false); mDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED, mDrawerList); Now old v4 support library ActionBarDrawerToggle became deprecated. I've switched to v7 version together

问题 In the Facebook app v2.3, when you navigate from one activity(or frgament?) to another, the actionbar stays fixed across all activities(or fragments?).

So my question is, is it possible to have this behavior using only activities? Or should i just have one main activity, and fragments for all sub activities? 回答1: One activity and as many fragments as

The reason for the custom layout is that I want a button that has two lines of text that can be updated dynamically. However, I still want this action button to operate like the other standard buttons. By this I mean that the background fades in when the button is selected, and fades out again if it is unselected, all
