即使使用getChildFragmentManager递归进入executePendingTransactions

Question

我有一个包含3个片段的viewpager活动。 在其中一个片段中，我有另一个viewpager，现在我知道当你想要在片段中嵌入一个片段时，你必须使用getChildFragmentManager，但由于某种原因它不适用于我。

我有一个活动： HomeActivity

而且3个片段，其中的一个： ProfileFragment

在这里我用这对我viewpager：

// Creating The ViewPagerAdapter and Passing Fragment Manager, Titles fot the Tabs and Number Of Tabs. 
     adapter = new ViewPagerProfileAdapter(getChildFragmentManager(),Titles,Numboftabs); 

     // Assigning ViewPager View and setting the adapter 
     pager = (ViewPager) getActivity().findViewById(R.id.pager); 
     pager.setAdapter(adapter); 

     // Assiging the Sliding Tab Layout View 
     tabs = (SlidingTabLayout) getActivity().findViewById(R.id.tabs); 
     tabs.setDistributeEvenly(true); // To make the Tabs Fixed set this true, This makes the tabs Space Evenly in Available width 

     // Setting Custom Color for the Scroll bar indicator of the Tab View 
     tabs.setCustomTabColorizer(new SlidingTabLayout.TabColorizer() { 
      @Override 
      public int getIndicatorColor(int position) { 
       return getResources().getColor(R.color.white); 
      } 
     }); 

     // Setting the ViewPager For the SlidingTabsLayout 
     tabs.setViewPager(pager); 

这是ViewPagerProfileAdapter：

public class ViewPagerProfileAdapter extends FragmentStatePagerAdapter { 

    CharSequence Titles[]; // This will Store the Titles of the Tabs which are Going to be passed when ViewPagerAdapter is created 
    int NumbOfTabs; // Store the number of tabs, this will also be passed when the ViewPagerAdapter is created 


    // Build a Constructor and assign the passed Values to appropriate values in the class 
    public ViewPagerProfileAdapter(FragmentManager fm,CharSequence mTitles[], int mNumbOfTabsumb) { 
     super(fm); 

     this.Titles = mTitles; 
     this.NumbOfTabs = mNumbOfTabsumb; 

    } 

    //This method return the fragment for the every position in the View Pager 
    @Override 
    public Fragment getItem(int position) { 

     if(position == 0) // if the position is 0 we are returning the First tab 
     { 
      EventsFragment tab1 = new EventsFragment(); 
      return tab1; 
     } 
     else   // As we are having 3 tabs if the position is now 0 it must be 1 so we are returning second tab 
     { 
      AttendsFragment tab2 = new AttendsFragment(); 
      return tab2; 
     } 


    } 

    // This method return the titles for the Tabs in the Tab Strip 

    @Override 
    public CharSequence getPageTitle(int position) { 
     return Titles[position]; 
    } 

    // This method return the Number of tabs for the tabs Strip 

    @Override 
    public int getCount() { 
     return NumbOfTabs; 
    } 
} 

我仍然得到这个错误：206

线是pager.setAdapter（适配器）;

Answer 1

我自己找到了。 对于每个使用getChildFragmentManager但仍有错误的人。 为寻呼机和选项卡指定一个不同的名称，否则它将无法工作，并干扰其他寻呼机和选项卡。
