嘿我想将数据从FragmentStatePagerAdapter
传递到fragment
。
我该怎么办?
FragmentStatePagerAdapter
public class ScreenSlidePagerActivity extends Fragment {
/**
* The number of pages (wizard steps) to show in this demo.
*/
/**
* The pager widget, which handles animation and allows swiping horizontally to access previous
* and next wizard steps.
*/
private ViewPager mPager;
/**
* The pager adapter, which provides the pages to the view pager widget.
*/
private PagerAdapter mPagerAdapter;
private String[] Titel;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
final View layout = inflater.inflate(R.layout.viewpage, container, false);
ArrayList<String> strtext=getArguments().getStringArrayList("key");
String frnames[]=strtext.toArray(new String[strtext.size()]);
Titel = frnames;
// Instantiate a ViewPager and a PagerAdapter.
mPager = (ViewPager) layout.findViewById(R.id.viewPager);
mPagerAdapter = new ScreenSlidePagerAdapter(getFragmentManager());
mPager.setAdapter(mPagerAdapter);
return layout;
}
/**
* A simple pager adapter that represents 5 ScreenSlidePageFragment objects, in
* sequence.
*/
private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter {
public ScreenSlidePagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
return new ScreenSlidePageFragment();
}
@Override
public int getCount() {
return Titel.length;
}
}
碎片
public class ScreenSlidePageFragment extends Fragment {
String[] Titel;
private static final Map<String, Integer> TITLE_IMAGES =
new HashMap<String, Integer>();
static {
TITLE_IMAGES.put("Arme", R.drawable.ic_launcher);
TITLE_IMAGES.put("Bauch", R.drawable.ic_launcher2);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
ViewGroup rootView = (ViewGroup) inflater.inflate(
R.layout.swipeview, container, false);
return rootView;
}
}
我想将Titel
从FragmentStatePagerAdapter
传递到fragment
。
