声明一个TabBarView ，同时将ViewPager传递给它：LayoutInflater inflator =
(LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = inflator.inflate(R.layout.custom_ab, null);
tabBarView = (TabBarView) v.findViewById(R.id.tab_bar);
getActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
getActionBar().setCustomView(v);
// Create the adapter that will return a fragment for each of the three
// primary sections of the activity.
mSectionsPagerAdapter = new SectionsPagerAdapter(getFragmentManager());
// Set up the ViewPager with the sections adapter.
mViewPager = (ViewPager) findViewById(R.id.pager);
mViewPager.setAdapter(mSectionsPagerAdapter);
tabBarView.setViewPager(mViewPager);
同时，要TabBarView起作用，需要一个这样的adapter：public class SectionsPagerAdapter extends FragmentPagerAdapter implements IconTabProvider{
private int[] tab_icons={R.drawable.ic_tab1,
R.drawable.ic_tab2,
R.drawable.ic_tab3,
};
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
// getItem is called to instantiate the fragment for the given page.
// Return a PlaceholderFragment (defined as a static inner class
// below).
return PlaceholderFragment.newInstance(position + 1);
}
@Override
public int getCount() {
// Show 3 total pages.
return tab_icons.length;
}
@Override
public int getPageIconResId(int position) {
return tab_icons[position];
}
@Override
public CharSequence getPageTitle(int position) {
Locale l = Locale.getDefault();
switch (position) {
case 0:
return getString(R.string.title_section1).toUpperCase(l);
case 1:
return getString(R.string.title_section2).toUpperCase(l);
case 2:
return getString(R.string.title_section3).toUpperCase(l);
}
return null;
}
}
