在android中動態創建選項卡

嗨，朋友們，請幫助我。我被困在這裏超過2天，我不明白這裏的錯誤是什麼。我的問題是，我正在創建基於JSON數據的帶有圖標的Tabs，問題是圖標即將到來，但當剩餘數據加載到fragments.but中時，它們消失了。但是，當我刪除適配器時，圖標即將到來，它們是在這裏可見，我發現了一個錯誤，當我評論此行sticker_tab.setupWithViewPager（sticker_pager）;然後一切工作正常，但不能移動基礎上，viewpager變化或反之亦然 這裏的標籤是我的代碼：在android中動態創建選項卡

OnResponse？ – user3040153

我認爲，因爲我們需要更改主線程上的文本或適配器na –

onResponse僅在UI線程上工作 – user3040153

基於viewpager更改標籤：

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) { 

       } 
      });

runOnUiThread(new Runnable() {

           Constant.l("Tab Count===>" + String.valueOf(sticker_tab.getTabCount()));

           Constant.l(e.toString());

         sticker_pager.setAdapter(chat_sticker_adapter); 
         sticker_tab.setupWithViewPager(sticker_pager); 
        } 
       }); 

combine this

在這裏我發現了一個bug，當我評論這行sticker_tab.setupWithViewPager（sticker_pager）;然後一切工作正常，但不能移動基於viewpager選項卡更改 –

我已經做了，但同樣的問題 –

在此之後ViewPager實現可以動態創建標籤：你爲什麼要使用runOnUiThread在

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; 
    }
