TabLayout e ViewPager - Fare clic sulle schede non funziona dopo aver fatto scorrere l'elemento del cassetto scorrevole.TabLayout e ViewPager -Tabs non funziona dopo lo scorrimento tra gli elementi del cassetto scorrevole
Io lavoro su app che hanno cassetto scorrevole e Tablayout. Mi riferisco a questo tutorial For Sliding Drawer e For TabLayout.
All'interno scorrevole cassetti
- Tasklist ->
TabLayout(Tabs(Today,Monthly,Yearly))
- Impostazioni
- Ordini
ho questione tra cassetto scorrevole e Tablayout. prima volta che viewpager viene caricato correttamente. ma quando mi sposto alla voce successiva del cassetto come (Frammento impostazioni) dopo di che tornare al frammento della scheda TaskList viewpager non posso caricare alcun frammento, quando scorri il cercapersone e carica pochi frammenti.
Qui codice Java
public class TaskListFragment extends Fragment {
private Toolbar toolbar;
private TabLayout tabLayout;
private ViewPager viewPager;
public TaskListFragment() {
// Required empty public constructor
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_my_page, container, false);
viewPager = (ViewPager)rootView.findViewById(R.id.viewpager);
tabLayout = (TabLayout)rootView.findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
@Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager.setCurrentItem(tab.getPosition());
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
}
@Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
// Inflate the layout for this fragment
return rootView;
}
private void setupViewPager(ViewPager viewPager) {
ViewPagerAdapter adapter = new ViewPagerAdapter(getFragmentManager());
adapter.addFragment(new Mypage_TodayFragment(), "TODAY");
adapter.addFragment(new Mypage_TodayFragment(), "WEEKLY");
adapter.addFragment(new Mypage_TodayFragment(), "MONTHLY");
viewPager.setAdapter(adapter);
}
class ViewPagerAdapter extends FragmentPagerAdapter {
private final List<Fragment> mFragmentList = new ArrayList<>();
private final List<String> mFragmentTitleList = new ArrayList<>();
public ViewPagerAdapter(FragmentManager manager) {
super(manager);
}
@Override
public Fragment getItem(int position) {
return mFragmentList.get(position);
}
@Override
public int getCount() {
return mFragmentList.size();
}
public void addFragment(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
@Override
public CharSequence getPageTitle(int position) {
return mFragmentTitleList.get(position);
}
}
@Override
public void onAttach(Activity activity) {
super.onAttach(activity);
}
@Override
public void onDetach() {
super.onDetach();
}
Qui .XML Codice
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="262dp"
android:id="@+id/view"
android:layout_weight="0.16">
<android.support.design.widget.TabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabMode="fixed"
app:tabGravity="fill"
app:tabBackground="@drawable/mytabselector"
app:tabIndicatorColor="@color/Orange" />
<android.support.v4.view.ViewPager

Grazie in anticipo !!
Utilizzare 'FragmentStatePagerAdapter' invece di' F ragmentPagerAdapter' –
