【Android】java.lang.IllegalStateException: Recursive entry to executePendingTransactions

第一次使用没有问题（add），第二次使用时就报这个错（attach）。

场景

嵌套Fragment使用（最外层FragmentActivity，Fragment中使用ViewPager再嵌套Fragment使用）

解决两种可能两种方法:

一::嵌套Fragment设置PageAdapter时要使用getChildFragmentManager。

二:重写

@Override
public void onDetach() {
  super.onDetach();
  try {
   Field childFragmentManager = Fragment.class     .getDeclaredField("mChildFragmentManager");
   childFragmentManager.setAccessible(true);
   childFragmentManager.set(this, null);
  } catch (NoSuchFieldException e) {
   throw new RuntimeException(e);
  } catch (IllegalAccessException e) {
   throw new RuntimeException(e);
  }
}
