动作栏标签和ViewPager中的片段

Question

Is it possible to use a Fragment in both tablet Actionbar Tabs and phone ViewPager? It appears that the phone uses the support library and that isn't compatible with the TabListener in the Actionbar. Is there a trick to getting both to use the same Fragment?

The only possible workaround I've seen so far is this .

Thanks

Answer 1

Sure, check out the ActionBarTabsPager sample in the compatibility library source. You need to implement both interfaces in your adapter to handle tab switching and paging. Something like this:

public class TabsPagerAdapter extends FragmentPagerAdapter implements
        ViewPager.OnPageChangeListener, ActionBar.TabListener {
        // implement both
}

You need to add tabs like this (using the support/compatibility library):

getSupportActionBar().setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

viewPager = (ViewPager) findViewById(R.id.content);
tabsAdapter = new TabsPagerAdapter(this, getSupportActionBar(),
                viewPager);
ActionBar.Tab tab = getSupportActionBar().newTab();
MyFragment f = new MyFragment();
tabsAdapter.addTab(tab, f);

This is the good way to use Fragment from compatibility library with ActionBar.Tab and TabListener.

这是Nikolay Elenkov回答的TabsPagerAdapter https://wwwjdic.googlecode.com/svn-history/r684/branches/2.0/wwwjdic/src/org/nick/wwwjdic/TabsPagerAdapter.java的示例实现。

The idea is to use android-support-v13.jar. This file includes FragmentPagerAdapter for native fragments as well as ViewPager.
