Comment ajouter de la dynamique fragment onglet articles

Je veux ajouter de la dynamique de l'onglet articles. J'ai un fragment qui est FragmentOne et il a un TextView. Je suis en train de créer FragmentOne dans le foreach et ajouter à onglets. J'ai testé le code qui est dans setupViewPager mais ça ne fonctionne pas. Comment puis-je modifier TextView qui en fragments?

si je supprime cette ligne, il fonctionne, mais le contenu du fragment toujours afficher par défaut = "ONGLET". Je veux modifier tous les TextView qui est dans les fragments qui a créé au moment de l'exécution;

View view = fView.getView();

TextView txtTabItemNumber = (TextView)view.findViewById(R.id.txtTabItemNumber);
txtTabItemNumber.setText("TAB " + i);

DynamicTabsActivity.java

public class DynamicTabsActivity extends AppCompatActivity {
private Toolbar toolbar;
private TabLayout tabLayout;
private ViewPager viewPager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_dynamic_tabs);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
viewPager = (ViewPager) findViewById(R.id.viewpager);
setupViewPager(viewPager);
tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
}
private void setupViewPager(ViewPager viewPager) {
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
LayoutInflater inflator = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
int count = 10;
for (int i=0; i<count; i++){
OneFragment fView = new OneFragment();
View view = fView.getView();
TextView txtTabItemNumber = (TextView)view.findViewById(R.id.txtTabItemNumber);
txtTabItemNumber.setText("TAB " + i);
adapter.addFrag(fView,"TAB " + i);
}
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 addFrag(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
@Override
public CharSequence getPageTitle(int position) {
return mFragmentTitleList.get(position);
}
}
}

Comment ajouter de la dynamique fragment onglet articles

Veuillez ajouter le code de OneFragment.
il n'y a rien dans OneFragment juste valeur par défaut onCreateView et méthodes onCreate. J'ai aussi édité question

Le fragment de la mise en page n'a pas été créé au point que vous appelez findViewById ci-dessous:

        OneFragment fView = new OneFragment();
View view = fView.getView();
TextView txtTabItemNumber = (TextView)view.findViewById(R.id.txtTabItemNumber);

Suivant est plus généralement la manière dont c'est codé:

public static class OneFragment extends Fragment {
private static final String ARG_SECTION_NUMBER = "section_number";
private int sectionNumber;
public OneFragment() {
}
public static OneFragment newInstance(int sectionNumber) {
OneFragment fragment = new OneFragment();
Bundle args = new Bundle();
args.putInt(ARG_SECTION_NUMBER, sectionNumber);
fragment.setArguments(args);
return fragment;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_one, container, false);
sectionNumber = getArguments().getInt(ARG_SECTION_NUMBER);
TextView textView = (TextView) rootView.findViewById(R.id.txtTabItemNumber);
textView.setText("TAB " + sectionNumber);
return rootView;
}
}

vous pouvez également déplacer fragment de création en à la carte...par exemple:

    public Fragment getItem(int position) {
return OneFragment.newInstance(position + 1);
}

Après avoir essayé pendant longtemps...je suis venu avec la solution suivante:
DynamicTabsActivity est mon activité principale, ressemble à ceci:

public class DynamicTabsActivity extends AppCompatActivity {
private TabLayout tabLayout;
private ViewPager viewPager;
private ViewPagerAdapter viewPagerAdapter;
private int noOfTabs = 10;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_dynamic_tabs);
viewPagerAdapter = new ViewPagerAdapter(getSupportFragmentManager(), noOfTabs);
viewPager = findViewById(R.id.viewpager);
viewPager.setAdapter(viewPagerAdapter);
tabLayout = findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
}
}

Mon fragment ressemble à ceci:

public class DynamicFragment extends Fragment {
private static final String ARG_SECTION_NUMBER = "section_number";
private int sectionNumber;
public DynamicFragment() {
//Required empty public constructor
}
@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
sectionNumber = getArguments() != null ? getArguments().getInt(ARG_SECTION_NUMBER) : 1;
}
@Override
public View onCreateView(@NonNull LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
//Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_dynamic, container, false);
TextView textView = view.findViewById(R.id.txtTabItemNumber);
textView.setText("TAB " + sectionNumber);
return  view;
}
public static DynamicFragment newInstance(int sectionNumber) {
DynamicFragment fragment = new DynamicFragment();
Bundle args = new Bundle();
args.putInt(ARG_SECTION_NUMBER, sectionNumber);
fragment.setArguments(args);
return fragment;
}
}

Mon ViewPager Classe ressemble à ceci:

public class ViewPagerAdapter extends FragmentStatePagerAdapter {
private int noOfItems;
public ViewPagerAdapter(FragmentManager fm, int noOfItems) {
super(fm);
this.noOfItems = noOfItems;
}
@Override
public Fragment getItem(int position) {
return DynamicFragment.newInstance(position + 1);
}
@Override
public int getCount() {
return noOfItems;
}
@Override
public CharSequence getPageTitle(int position) {
return "TAB "+(position+1);
}
}

DynamicTabsActivity mise en page:

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".DynamicTabsActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />
<android.support.design.widget.TabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabMode="scrollable"/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="@+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
</android.support.constraint.ConstraintLayout>

Fragment de mise en page:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".DynamicFragment">
<TextView
android:id="@+id/txtTabItemNumber"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="TAB ONE"
android:textSize="40dp"
android:textStyle="bold" />
</RelativeLayout>

Espère que ça aide...

Essayer cela,

  LinearLayout  main = new LinearLayout(this);
main.setOrientation(LinearLayout.VERTICAL);
TextView textView = new TextView(this);
textView .setText("TAB " + i);
main .addView(textView );

Je suppose que vous avez eu la question de mal
