问题 I'm using a ViewPager to scroll between different fragments. There are two types of fragments, using two different menu resources. I'm invalidating the menu to switch between those resources when necessary. That's all working pretty well, but the menu is "redrawn" without an animation. To prevent having to mess with individual MenuItems I was hoping I could briefly hide the ActionBar while the new menu is loaded, showing it when that's done. That's working as expected as well, but the

问题 I need to implement a TextView in the ActionBar. This TextView shows the status of the bluetooth connection so it will update depending of this status.

At the moment, what I have done is create an item in the menu.xml: <item android:id="@+id/statusTextview" android:actionViewClass="android.widget.TextView" android:showAsAction="ifRoom" android:title="Disconected" /> Then Add it

问题 I need to temporarily hide the Tab objects I've defined for my ActionBar . There is no setVisibility method on Tab objects, so I'm at a loss as to how to accomplish this. 回答1: I'd try setNavigationMode(ActionBar.NAVIGATION_MODE_STANDARD) , to move back to the non-tab rendition. It's possible that, when you later call setNavigationMode(ActionBar.NAVIGATION_MODE_TABS) that you will need to re-establish your tabs, though. UPDATE : Note that action bar tabs are deprecated in the "L" Developer

问题 I would like to add an indeterminate progress bar to the Honeycomb ActionBar, so that any time the user presses "Refresh", the refresh icon temporarily turns into an indeterminate progress bar, until the task completes. The Email app does this already, but I can't figure out how. Any advice? 回答1: Hard to tell exactly how the Email app does it, but you may want to stay simple and just call setIcon with the id of a StateDrawable XML file, and then just change the state using a Timer. 回答2: To
