我有一个包含3个片段的viewpager活动。
在这3个片段之一中，我有另一个viewpager，现在我了解到，当您要将片段嵌入片段中时，必须使用getChildFragmentManager，但由于某些原因，它对我不起作用。
我有一个活动：
家庭活动
和3个片段，其中之一：
ProfileFragment
在这里，我将其用于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）;
最佳答案
我自己找到的。
对于确实使用getChildFragmentManager但仍然存在错误的每个人。
给传呼机和选项卡取一个不同的名称，否则它将不起作用，并且不能与您的其他传呼机和选项卡干涉。
关于java - 即使使用getChildFragmentManager，也可以递归执行到executePendingTransactions，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/29033192/
