IllegalStateException:无法更改片段的容器ID
IllegalStateException:无法更改片段的容器ID
提问于 2012-03-28 19:09:14
Android平台: 3.1
我正在尝试将一个片段从容器A移动到容器B。下面是完成此操作的代码：
private void reattach(int newContainerId, Fragment frag, String tag) {
if (frag == null || !frag.isAdded() || (frag.getId() == newContainerId)) { return; }
final FragmentManager fm = getFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.remove(frag); //stacco il frammento dal container A
ft.commit();
fm.executePendingTransactions();
ft = fm.beginTransaction();
ft.add(newContainerId, frag, tag); //attacco il frammento sul container D
ft.commit();
fm.executePendingTransactions();
}当我运行系统时，我得到以下IllegalStateException：

有什么建议或变通方法吗？
