I Have 4 Fragments in 1 Activity. I need to make sure that on every fragment change the fragment is refreshed because I load JSON Data in every fragment. I use FragmentPager Adapter and RecyclerView to Show Data
This is my Adapter ( SickAdapter.java ) the code :
public class SickAdapter extends FragmentPagerAdapter{
private static final String TAG = SickAdapter.class.getSimpleName();
private static final int FRAGMENT_COUNT = 4;
public SickAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
switch (position){
case 0:
return new SickFragmentToAll();
case 1:
return new SickFragmentToPending();
case 2:
return new SickFragmentToApproved();
case 3:
return new SickFragmentToDenied();
}
return null;
}
@Override
public int getCount() {
return FRAGMENT_COUNT;
}
@Override
public CharSequence getPageTitle(int position) {
switch (position){
case 0:
return "All";
case 1:
return "Pending";
case 2:
return "Approved";
case 3:
return "Denied";
}
return null;
}
}
In my Class ( SickClass.java ) I create SickClass and I Call SickAdapter, I explode them, and this is my Code :
public class SickClass extends Fragment {
private static final String TAG = SickClass.class.getSimpleName();
private SickAdapter mAdapter;
private TabLayout tabLayout;
private ViewPager viewPager;
public SickClass() {
}
@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.employee_leave_class, container, false);
tabLayout = (TabLayout)view.findViewById(R.id.tabs);
viewPager = (ViewPager)view.findViewById(R.id.view_pager);
if(mAdapter == null) {
mAdapter = new SickAdapter(getChildFragmentManager());
}
viewPager.setAdapter(new SickAdapter(getChildFragmentManager()));
tabLayout.setupWithViewPager(viewPager);
viewPager.setCurrentItem(1, true);
tabLayout.post(new Runnable() {
@Override
public void run() {
tabLayout.setupWithViewPager(viewPager);
}
});
return view;
}
}
