同样在developers guide中提到.

我试图使用这个approch来恢复我的片段的状态.
我的目的是在片段恢复时在onActivityCreated()中调用此包.

虽然在片段失去焦点之前调用onSaveInstanceState.
但是,当调用onActivityCreated()时,它会将Bundle savedInstanceState作为null返回.

如何从捆绑包中获取数据.

码：

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);

    MyListAdapter adapter = new MyListAdapter(getActivity(),R.layout.my_row,titles,icons,this);

    setListAdapter(adapter);

    if (savedInstanceState != null) {
        // Never goes inside this condiiton.
        // Restore last state for checked position.
        mCurCheckPosition = savedInstanceState.getInt("curChoice",0);
    }
}

@Override
public void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    outState.putInt("curChoice",mCurCheckPosition);
}
