Erstellen von Registerkarten dynamisch in Android

-1

Hallo Freunde bitte hilf mir. Ich stecke hier für mehr als 2 Tage und ich verstehe nicht, was der Fehler hier ist. Mein Problem ist, dass ich die Tabs mit Icon basierend auf den JSON-Daten erstelle. Das Problem ist, dass Icons kommen, aber sie sind weg, wenn die restlichen Daten in den Fragmenten geladen werden. Aber wenn ich den Adapter entferne, kommen Icons und sie sind hier sichtbar Ich hatte einen Fehler gefunden, als ich diese Zeile sticker_tab.setupWithViewPager (sticker_pager) kommentieren; dann ist alles in Ordnung arbeiten, kann aber nicht auf die Registerkarte auf der Grundlage der viewpager Wechsel oder umgekehrt Hier ist mein Code bewegen:Erstellen von Registerkarten dynamisch in Android

warum verwenden Sie runOnUiThread in OnResponse? – user3040153

Ich denke, weil wir Text oder Adapter auf dem Hauptthread ändern müssen –

onResponse funktioniert nur auf UI-Thread – user3040153

Registerkarte zu ändern, basierend auf viewpager:

viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout)); 
     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) { 

       } 
      });

Aber wenn scrollen die Ansicht Pager Registerkarte nicht auswählen –

bearbeitet pls überprüfen – user3040153

Vielen Dank es funktioniert –

runOnUiThread(new Runnable() { 
         @Override 
         public void run() { 
          try { 
           sticker_tab.addTab(sticker_tab.newTab().setIcon(d)); 
           Constant.l("Tab Count===>" + String.valueOf(sticker_tab.getTabCount())); 
          } catch (Exception e) { 
           Constant.l(e.toString()); 
          } 

         } 
        }); 
       } 
       runOnUiThread(new Runnable() { 
        @Override 
        public void run() { 
         chat_sticker_adapter = new Chat_Sticker_Adapter(getSupportFragmentManager(), giftarray); 
         sticker_pager.setAdapter(chat_sticker_adapter); 
         sticker_tab.setupWithViewPager(sticker_pager); 
        } 
       }); 

combine this

eingefügt hier hatte ich einen Fehler gefunden, als ich diese Zeile kommentierte sticker_tab.setupWithViewPager (sticker_pager); dann funktioniert alles gut, aber kann nicht die Registerkarte basierend auf der Viewpager ändern –

Ich hatte getan, aber das gleiche Problem –

Nach dieser ViewPager Implementierung von Tabs dynamisch erstellen:

viewPager = (ViewPager) view.findViewById(R.id.viewPager); 

//adapter view 
androidAdapter = new ViewPagerAdapter(getFragmentManager()); 
viewPager.setAdapter(androidAdapter); 
viewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() { 
     @Override 
     public void onPageSelected(int tabposition) { 
      tabHost.setSelectedNavigationItem(tabposition); 
     } 
    }); 

//  role = 1; //admin 
//  role = 2; //master 
     role = 3; //student 

// Creating Dynamic TAB 
    switch (role){ 
     case 1: 
      break; 
     case 2: 
      // MASTERLOGIN 
      tabHost.addTab(tabHost.newTab().setText("Slot History").setTabListener(this)); 
      tabHost.addTab(tabHost.newTab().setText("Create Template").setTabListener(this)); 
      tabHost.addTab(tabHost.newTab().setText("Scheduled").setTabListener(this)); 
      tabHost.setSelectedNavigationItem(1); 
      viewPager.setCurrentItem(1); 
      //--MASTERLOGIN 
      break; 
     case 3: 
      //STUDENTLOGIN 
      tabHost.addTab(tabHost.newTab().setText("Products").setTabListener(this)); 
      tabHost.addTab(tabHost.newTab().setText("Book A Slot").setTabListener(this)); 
      tabHost.addTab(tabHost.newTab().setText("Scheduled").setTabListener(this)); 
      tabHost.setSelectedNavigationItem(1); 
      viewPager.setCurrentItem(1); 
      //--STUDENT LOGIN 
      break; 
     default: 
      break; 
    }

Danke, aber Ihre Antwort, aber die Antwort akzeptieren ist user3040153, als er mir geholfen hat, Problem aus dem Kern zu lösen, sorry –

@orienlxoxoorienlalxoxo Es ist ok! Keine Probleme, aber immer den besten Ansatz folgen. –
