片段上没有调用onSaveInstanceState

Question

我正在用另一个片段替换片段：

    FragmentTransaction transaction = mFragmentManager.beginTransaction();

    transaction.setCustomAnimations(R.anim.enter, R.anim.exit, R.anim.pop_enter, R.anim.pop_exit);
    transaction.replace(R.id.main_container, nextFragment, nextFragment.getClass().toString());
    transaction.addToBackStack(nextFragment.getClass().toString());
    transaction.commit();

然而，被替换的片段，其onSaveInstanceState未被调用。我做错了什么？

Answer 1

＆＃34;在片段中，所有生命周期回调都直接与其父Activity相关联。因此，当其父Activity调用onSaveInstanceState时，会在Fragment上调用onSaveInstanceState。＆＃34;

看看这篇文章：
