问题 I have a toolbar, to which I have attached a sliding tab layout, using these two classes: SlidingTabLayout, SlidingTabStrip. When I long press an item, the contextual action bar appears and overlays the toolbar, using <item name="windowActionModeOverlay">true</item> in my styles.xml. The problem is that the Tabs are still clickable, and swipable. I have tried setClickable(false) , which didn't work. How do I make the tabs not clickable, so that I can then change the "state look" of the tabs

问题 I'm building an app with MainActivity which extends FragmentActivity and has an ActionBar with three tabs. At each tab I would like to attach a ParentFragment which should control the swipe among internal pages. The result should be that pressing the tabs the user should change from the different instances of the ParentFragment and swiping he should change among the TextViewFragments inside each ParentFragment .

问题 I have an ActionBar that contains 11 tabs and 1 fragment. I also have a ViewPager to display the fragment(s). When a tab is clicked it creates the same fragment. The tabs display dates so they change everyday. What I need is to send the text of the tab (ie. .getTabText()) to the fragment, this will change the content of the fragment. I am having so much trouble trying to figure out how to do this. Here is all my code: public class MainActivity extends FragmentActivity implements ActionBar

问题 I'd like to have a layout where screen real estate is important on smaller screens, but I'd like users to be able to swipe between exactly two tabs. On these smaller screened devices, I don't want to waste an entire row with a scrollable tab widget like this: but fixed tabs offer no indication to users that they can swipe: Users will typically need to view both tabs to complete the task. Is there any way presently to embed tabs with support for "swipe to switch tabs" inside the main action
