And one more moment: if I add targetSdkVersion = 11 to manifest and do list adapter without SectionIndexer implementing, scrollbar works fine too. But i need targetSdkVersion = 11 or more, and need

问题 I have an Activity which has a Action Bar on the top with a Search View.

问题 I've set up an ActionMode callback for use as the contextual ActionBar (CAB) within an ActionBarSherlock using project. I'm trying to set up multiple select so that I can delete multiple items in a ListView .

Please have a look at my code below... fragment_news_list.xml <?xml version="1.0" encoding="utf-8"?> <uk.co.senab.actionbarpulltorefresh
