// 保存@Overrideprotected void onSaveInstanceState(Bundle outState) {    super.onSaveInstanceState(outState);    getSupportFragmentManager().putFragment(outState, KEY, targetFragment);}// 恢复@Overrideprotected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_scrolling);    if (savedInstanceState != null) {        Fragment targetFragment = getSupportFragmentManager().getFragment(savedInstanceState, KEY);    }｝
