android-support-library

问题 I'm currently trying to adapt my application to use the "Compatibility Libraries for Android v4" to provide the benefits of the usage of fragments even to Android 1.6 users. The implementation of a context menu seems to be tricky: The main activity of the application is extending the FragmentActivity class. The fragments are all based on one class which extends the Fragment class. The fragment class is calling registerForContextMenu() in its onCreateView() method and overrides the methods

问题 I imported the v7-appcompat support library following the instructions on the android developer site, and ran into the missing R issue that many other users have encountered. I've read through several similar questions users have posted here, and tried what was suggested but I'm still getting the missing R problem.

I also tried importing the support.app.v4 namespace but that will only make the ScreenSlidePagerAdapter's FragmentManager throw a type error. DialogFragment Class which

问题 I'm trying to build a drop down menu in the Action Bar Compat, as per the dev example: http://developer.android.com/guide/topics/ui/actionbar.html#Dropdown I can't get onNavigationItemSelected to fire though. The spinner dropdown item in the action bar is being generated, to the right of the actionbar's Title. When I press it I do see the triangle icon turn blue.
