在那里我做我的活动MyActivity.m_oPager.setCurrentItem(iCurrentView);它与下面这个适配器相关线路：

public class FragmentPagerAdapter extends FragmentPagerAdapter 
    { 
     final int PAGE_COUNT_LOGGED_IN = 5; 
     final int PAGE_COUNT_LOGGED_OUT = 2; 
     TextView oTextView = null; 
     LayoutInflater inflater = null; 
     PagerTabStrip m_oPageTabStrip = null; 
     String m_strTab = null; 
     String[] m_strArray = null;  
     Context m_oContext = null; 

     /** Constructor of the class */ 
     public FragmentPagerAdapter (Context context, FragmentManager oFragmentManager) 
     { 
      super (oFragmentManager); 
      m_oContext = context; 
     } 


     /** This method will be invoked when a page is requested to create */ 
     @Override 
     public Fragment getItem(int arg0) 
     {  
      Fragment myFragment = new Fragment(); 
      Bundle data = new Bundle(); 
      data.putInt("current_page", arg0+1); 
      myFragment.setArguments(data); 
      return myFragment; 
     } 

     /** Returns the number of pages */ 
     @Override 
     public int getCount() 
     {  
      if (Utility.m_bIsLoggedIn == true) 
      { 
       return PAGE_COUNT_LOGGED_IN; 
      } 
      else 
      { 
       return PAGE_COUNT_LOGGED_OUT; 
      } 
     } 

     @Override 
     public CharSequence getPageTitle(int position) 
     { 
      String strText = " "; 

      switch(position) 
      { 
      case 0: 
       strText = ""; 
       break; 
      case 1: 
       strText = ""; 
       break; 
      case 2: 
       strText = ""; 
       break; 
      case 3: 
       strText = ""; 
       break; 
      case 4: 
       strText = ""; 
       break; 
      } 

      Spannable s = Spannable.Factory.getInstance().newSpannable(strText); 
      Typeface tt = Typeface.createFromAsset(m_oContext.getAssets(), "fonts/fontinsansbolditalic.ttf"); 
      s.setSpan (new CustomTypefaceSpan ("", tt), 0, strText.length(),Spanned.SPAN_EXCLUSIVE_INCLUSIVE); 
      return s; 
     } 
    } 

Answer 1

使用getChildFragmentManager()时创建FragmentPagerAdapter。例如：

new FragmentPagerAdapter(getChildFragmentManager()); 

Answer 2

使用最新版本的支持库，因为旧版本的supportLibrary不允许嵌套片段。
