java - 递归进入executePendingTransactions，即使使用getChildFragmentManager

Question

我有一个带有 viewpager 的 Activity ，其中包含 3 个 fragment 。 在 3 个 fragment 之一中，我有另一个 viewpager，现在我了解到，当您想要在 fragment 中嵌入 fragment 时，您必须使用 getChildFragmentManager，但由于某种原因，它不适用于我。

我有一个 Activity : 首页 Activity

还有 3 个 fragment ，其中之一: 配置文件 fragment

在这里我将其用于我的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;
    }
}

我仍然收到此错误:

第206行是pager.setAdapter(adapter);

我自己找到的。 对于每个使用 getChildFragmentManager 但仍然有错误的人。 为寻呼机和选项卡指定不同的名称，否则它将无法工作并干扰您的其他寻呼机和选项卡。
