Verilerin ViewPager ile Fragments'a aktarılması

Question

Çok araştırdım ve durumum için bir çözüm bulamadım.

Bu

benim Hareketi:

public class ProfileActivity extends AppCompatActivity { 



@Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 



     setContentView(R.layout.activity_profile); 



     //region FindViews 
     toolbar = (Toolbar) findViewById(R.id.toolbar); 
     viewPager = (ViewPager) findViewById(R.id.viewpager); 
     tabLayout = (PagerSlidingTabStrip) findViewById(R.id.tabs); 
     //endregion 

     //region ViewPager 
     setSupportActionBar(toolbar); 
     getSupportActionBar().setDisplayHomeAsUpEnabled(true); 
     setupViewPager(viewPager); 
     viewPager.setOffscreenPageLimit(5); 
//  tabLayout.setupWithViewPager(viewPager); 
     tabLayout.setViewPager(viewPager); 
     viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() { 
      @Override 
      public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) { 

      } 

      @Override 
      public void onPageSelected(int position) { 
       switch (position) { 
        case 0: 
         changeColor(ContextCompat.getColor(getApplicationContext(), R.color.theme_red_primary)); 
         break; 
        case 1: 
         changeColor(ContextCompat.getColor(getApplicationContext(), R.color.theme_yellow_primary)); 
         break; 
        case 2: 
         changeColor(ContextCompat.getColor(getApplicationContext(), R.color.theme_green_primary)); 
         break; 
        case 3: 
         changeColor(ContextCompat.getColor(getApplicationContext(), R.color.theme_blue_primary)); 
         break; 
        case 4: 
         changeColor(ContextCompat.getColor(getApplicationContext(), R.color.theme_black_primary)); 
         break; 
       } 
      } 

      @Override 
      public void onPageScrollStateChanged(int state) { 

      } 
     }); 
     //endregion 

     extrasForFragment = new Bundle(); 
     extrasForFragment.putInt("name", 3); 

     //region Get Extras from Intent 
     extras = getIntent().getExtras(); 
     if (extras != null) { 
      userID = extras.getInt(StaticVariables.INTENT_USERID, -1); 
      Log.e("ISER", "dd " + userID); 
      OverViewFragment.newInstance().setArguments(extrasForFragment); 
     } 
     //endregion 

     setTitle(""); 
    } 

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); 
     } 
    } 





private void setupViewPager(ViewPager viewPager) { 
     ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager()); 
     adapter.addFrag(OverViewFragment.newInstance(), getString(R.string.overview)); 
     adapter.addFrag(new Fragment2(), getString(R.string.text)); 
     adapter.addFrag(new Fragment3(), getString(R.string.text)); 
     adapter.addFrag(new Fragment4(), getString(R.string.text)); 
     adapter.addFrag(new Fragment5(), getString(R.string.text)); 
     viewPager.setAdapter(adapter); 
    } 
} 

Ama .. Bu benim parçasıdır çalışmaz:

public class OverViewFragment extends Fragment { 
public static OverViewFragment newInstance() { 
     return new OverViewFragment(); 
    } 
@Override 
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { 
     Bundle b = getArguments(); 
     if (b != null) { 
      Log.e("EXTRAS", "sind: " + b.toString() + " und: " + b.getInt("name", 0)); 
     } else { 
      Log.e("FAIL", "..."); 
     } 
     return inflater.inflate(R.layout.fragment_recyclerview, container, false); 
    } 
} 

Ama işe yaramadı. Send data from activity to fragment in android ve bu: Passing value between activity to fragment on android Ama hiçbir şey çalışmak istiyorum .. Ben çözümler için umut Bu çalıştı. Herhangi bir yardım için teşekkürler!

setArguments aradığınız tek adres ViewPager ürününüzde kullanılmayan OverViewFragment.newInstance().setArguments(extrasForFragment); hattında.

Fragment overviewFrag = OverViewFragment.newInstance(); 
overviewFrag.setArguments(<args_bundle>); 
adapter.addFrag(overviewFrag, getString(R.string.overview));
