Content not updating on changing tabs in viewpager - Tablayout - android

I am storing dynamic ids from arraylist to each tabs that are created dynamically and
I have used ViewPagerOnTabSelectedListener , and it is getting id of the tab that is clicked and stores it in a sharedpreference.
I am using that id from sharedpreference into fragment get the customlist in each tab based on that id.
NOw, the problem is the customlist is not getting refreshed on tab click , but it has already fetched old values , its not getting updated as per the id from the sharedpreference

you can try this
#Override
public void onTabSelected(TabLayout.Tab tab) {
CharSequence numTab = tab.getTag().toString();
SharedPreferences preferences2 = getSharedPreferences("AUTHENTICATION_FILE_NAME2", Context.MODE_WORLD_WRITEABLE);
SharedPreferences.Editor editor2 = preferences2.edit();
editor2.putString("tabselected",numTab.toString());
editor2.putString("Authentication_Status", "true");
editor2.apply();
// super called last
super.onTabSelected(tab);
}
or store ViewPagerAdapter adapter "globally" on top of ScrollableTabsActivity (not only inside setupViewPager method)
ViewPagerAdapter adapter;
private void setupViewPager(ViewPager viewPager) {
adapter = new ViewPagerAdapter(getSupportFragmentManager());
//rest of your code
}
and then
#Override
public void onTabSelected(TabLayout.Tab tab) {
// your current code
adapter.notifyDataSetChanged(); //ViewPagerAdapter's adapter
}


There might be several Solution to this issue i.e.
1.) Load all your data at once if you have less data and less tabs and also you can increase
viewPager.setOffscreenPageLimit(noOfTabs);
2.) Update your fragment once it is visible to the user.
#Override
public void setUserVisibleHint(boolean isVisibleToUser) {
super.setUserVisibleHint(isVisibleToUser);
if (isVisibleToUser){
// load data
}
}
Hope that will be helpful.

Dynamic update of a view (viewpager) for news application

I can not implement a data update of a Viewpager based fragment.
In fact I have a service that verifies and retrieves the latest information updates published online and comes to feed my database.
Once the job is finished I should update the screen but that's where I'm stuck.
I tried many techniques but until then I have not yet received to update the screen.
I am so overwhelmed by the subject that I do not have the right words.
Thanks for your help

Below is my Activity class where I add all the tab
private void setupViewPager(ViewPager viewPager) {
int numberOfPages=7;
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFragment(new NewMatches_Tab(), "New matches");
adapter.addFragment(new Broader_Match_Tab(), "Broader Matches");
adapter.addFragment(new Similar_Matchs_Tab(), "Similar Matches");
adapter.addFragment(new ShortlistTab(), "ShortListed");
adapter.addFragment(new Viewed_My_Profile(), "View My Profile");
adapter.addFragment(new ShortListedMeTab(), "ShortListed Me");
adapter.addFragment(new Photo_Request_Received(), "Photo Request Received");
//viewPager.setOffscreenPageLimit(numberOfPages);
viewPager.setAdapter(adapter);
}

You can add an OnPageChangeListener in the activity and register it to your view pager and do all necessary "setting" within the OnPageChangeListener instance.
ViewPager.OnPageChangeListener viewPagerPageChangeListener = new ViewPager.OnPageChangeListener() {
#Override
public void onPageSelected(int position) {
//Do your fragment refreshing here
mCurrentPage = position;
}
#Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
#Override
public void onPageScrollStateChanged(int arg0) {
}
};
#Override
public void setFragmentsForContents(List<Content> contents) { //bundle data for your different fragments
if(contents!=null){
NUM_PAGES = contents.size();
mContentPager.addOnPageChangeListener(viewPagerPageChangeListener);
mContentPager.setAdapter(mScreenSlidePagerAdapter);
mContentPager.setCurrentItem(mCurrentPage);
}
}
private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter {
ScreenSlidePagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int position) {
return ContentFragment.newInstance(mContents.get(position).getContent());
}
#Override
public int getCount() {
return NUM_PAGES;
}
#NonNull
#Override
public Object instantiateItem(ViewGroup container, int position) {
return super.instantiateItem(container, position);
}
#Override
public float getPageWidth(int position) {
return 1.0f;
}
}

Tablayout on swipe not refreshing in android

I am implementing tablayout using view pager and in my scenario I have two tab. In my first tab I have add data which store in share preference. and when I move to second tab then data should be retrieve from share preference and show in listview. When I add the data from my first tab then data is added successfully but not show in my second tab means I have to close my application and again restart the app so that I can see saved the detail which saved from my first tab.
Below is my Activity code.
public class FragmentExample extends AppCompatActivity {
private ViewPagerAdapter viewPagerAdapter;
#BindView(R.id.tabCountryState)
TabLayout tabCountryState;
#BindView(R.id.viewPager)
ViewPager viewPager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_fragment_example);
ButterKnife.bind(this);
setViewPager();
setTabIcon();
viewPager.setOffscreenPageLimit(2);
tabCountryState.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
#Override
public void onTabSelected(TabLayout.Tab tab) {
Log.e("Current tab is ", "===> " + tab.getPosition());
}
#Override
public void onTabUnselected(TabLayout.Tab tab) {
}
#Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
}
private void setViewPager() {
// set Adaapter.
viewPagerAdapter = new ViewPagerAdapter(getSupportFragmentManager(), FragmentExample.this);
viewPager.setAdapter(viewPagerAdapter);
tabCountryState.setupWithViewPager(viewPager);
}
// set custom icon to tab in Tablayout.
private void setTabIcon() {
// First Tab
View firstTab = (View) LayoutInflater.from(this).inflate(R.layout.tab_icon_first, null);

tvFirsIcon.setText("First Tab");
tabCountryState.getTabAt(0).setCustomView(firstTab);
// First Tab
View secondTab = (View) LayoutInflater.from(this).inflate(R.layout.tab_icon_second, null);

And I am saving data into Share preference which is given below.

for(int i=0;i<cityName.size();i++){
Log.e("cityName "," in session ==> "+cityName.get(i).getStrCity());
}
}
} catch (Exception e) {

users = Arrays.asList(userItems);
users= new ArrayList<AllStateCityModel>(users);
}
return (ArrayList<AllStateCityModel>) users;
}
}
When I add new city detail into first tab then data is data successfully but when I swipe or move to next then data is not displaying and I have to restart whole application to get updated data from Share preference. Kindly help me to resolve this issue. Thanks in advance.

Here i am using NavigationDrawer for my activities.It is working fine.i am using Recyclerview for displaying NavigationDrawer items. Now i want to display different NavigationDrawer Item for different Activity..Here i am using nav_drawer_labels in FragmentDrawer to display items.How to display nav_drawer_labels1 in another activity.I mean i have to display different NavigationDrawer in each activity..here is my code.

Navigation drawer is meant to be used with fragments.
The main activity host the the nav drawer.
Fragments make it easy to swap the drawer content a keep its state.
If you wanted to use acitvity instead then you should create a base activity conaining the drawer so that all your activities inherit from that activity.
This way the nav drawer can persist from activity to activity.

ViewPagerAdapter update fragment when starting again

I have the following ViewPagerAdapter:
private void setupViewPager(ViewPager viewPager) {
adapter = new ViewPagerAdapter(((AppCompatActivity)getActivity()).getSupportFragmentManager());
adapter.addFrag(new OwnerPendingBookingsFragment(), "Pendientes");
adapter.addFrag(new OwnerConfirmedBookingsFragment(), "Confirmados");
adapter.addFrag(new OwnerFinishedBookingsFragment(), "Finalizados");
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 android.support.v4.app.Fragment getItem(int position) {
return mFragmentList.get(position);
}
#Override
public int getCount() {
return mFragmentList.size();
}
public void addFrag(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
#Override
public CharSequence getPageTitle(int position) {
return mFragmentTitleList.get(position);
}
}
And one of the fragments that I use is like that:
public class OwnerConfirmedBookingsFragment extends Fragment {
private View myView;
private ListView booking_list;
private ArrayAdapter adapter;
private SharedPreferences preferences;
private Toast toast;
private ProgressDialog progressDialog;
private BookingList bookings;
private boolean isFirstTime;
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
if (isFirstTime) {
myView = inflater.inflate(R.layout.owner_confirmed_bookings_layout, container, false);
isFirstTime = false;
}
return myView;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
isFirstTime = true;
//Getting out sharedpreferences
preferences = getActivity().getSharedPreferences(Config.SHARED_PREF_LOGIN, Context.MODE_PRIVATE);
new FindBookings().execute("");
}
private void setUpAdapter(){
booking_list = (ListView) myView.findViewById(R.id.owner_confirmed_bookings);
getActivity().setTitle("Nuevas solicitudes");
if(bookings.getBookings().size() == 0){
booking_list.setVisibility(View.GONE);
LinearLayout no_vehicles = (LinearLayout) myView.findViewById(R.id.no_confirmed_bookings_layout);
no_vehicles.setVisibility(View.VISIBLE);
}else {
for (int i = 0; i < bookings.getBookings().size(); i++){
try {
new setImageTask(i).execute(bookings.getBookings().get(i).getDriver_image()).get();
} catch (InterruptedException e) {
e.printStackTrace();
} catch (ExecutionException e) {
e.printStackTrace();
}
}
adapter = new OwnerFinishedBookingsAdapter(myView.getContext(), bookings.getBookings());
booking_list.setAdapter(adapter);
booking_list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
int booking_line = bookings.getBookings().get(position).getBooking_line_id();
Fragment booking_info = new OwnerPendingBookingInfoFragment();
Bundle args = new Bundle();
args.putInt("bookingLine", booking_line);
booking_info.setArguments(args);
FragmentTransaction transaction = getFragmentManager().beginTransaction();
transaction.replace(R.id.content_frame, booking_info);
transaction.addToBackStack(null);
transaction.commit();
}
});
}
}
private class FindBookings extends AsyncTask<String, Void, String> {
String token = preferences.getString(Config.TOKEN, "");
#Override
protected void onPreExecute() {
toast = Toast.makeText(getActivity().getApplicationContext(), "", Toast.LENGTH_LONG);
progressDialog = new ProgressDialog(getActivity());
progressDialog.setMessage(getActivity().getString(R.string.finding_bookings));
progressDialog.show();
}
#Override
protected void onPostExecute(String s){
if(bookings.getError() != 0){
if(bookings.getError() == Config.JWT_EXPIRED){
logout();
Toast.makeText(getActivity().getApplicationContext(),
getActivity().getString(R.string.session_expired),
Toast.LENGTH_LONG).show();
}else {
toast.setText(getActivity().getString(R.string.find_pendings_errror));
toast.show();
}
}else {
setUpAdapter();
}
progressDialog.dismiss();
}
#Override
protected String doInBackground(String... params) {
bookings = DBConnect.getPendingBookingList(preferences.getInt(Config.IDUSER, 0), token);
return "done";
}
}
The first time I use it, all the fragments loads without any problem. But when I go to another activity and then return it doesn't update the data. I debug it and onCreate and onCreateView are not firing?
I tried to remove the fragment when going to another activity but nothing worked for me.
