问题
The last revision of the support library from this morning (Android Support Package v4 revision 11) is supposed to support nested fragments.
In my project I have a fragment that contains a ViewPager and this ViewPager contains several fragments.
I'm calling getSupportFragmentManager()
instead of getFragmentManager
to use the FragmentManager of the support library.
The problem is I'm still experiencing crashes like :
java.lang.IllegalStateException: Recursive entry to executePendingTransactions

Is there anything I'm doing wrong ? Or the support doesn't support nested fragments for real ?
My transactions are as simple as this:
getSupportFragmentManager().beginTransaction()
.replace(R.id.content, new MyFragment()).commit();
回答1:
Try using getChildFragmentManager()
instead of getSupportFragmentManager()
. this should help
