android - 在 onSavedInstanceState(bundle savedInstanceState) 中存储和检索存储数据的问题

Question

考虑下面的 mCreate 等是 int 变量，它们动态增加 mCreate++。我需要存储和检索他们最新的增量值。我认为我做对了，但有些人没有应用最新的增量值。

  @Override
 public void onSaveInstanceState(Bundle savedInstanceState) {

    savedInstanceState.putInt(CREATE_KEY, mCreate);
    savedInstanceState.putInt( RESTART_KEY, mRestart);
    savedInstanceState.putInt(START_KEY, mStart);
    savedInstanceState.putInt(RESUME_KEY, mResume);

    super.onSaveInstanceState(savedInstanceState);

 }

 //////////// get 

  if (savedInstanceState != null) {

       mCreate = savedInstanceState.getInt(CREATE_KEY, mCreate);
       mRestart = savedInstanceState.getInt( RESTART_KEY, mRestart);
       mStart = savedInstanceState.getInt(START_KEY, mStart);
       mResume = savedInstanceState.getInt(RESUME_KEY, mResume);

    }

代码应该是这样的:

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

    savedInstanceState.putInt(CREATE_KEY, mCreate);
    savedInstanceState.putInt(RESTART_KEY, mRestart);
    savedInstanceState.putInt(START_KEY, mStart);
    savedInstanceState.putInt(RESUME_KEY, mResume);    
 }

 if (savedInstanceState != null) {
    mCreate = savedInstanceState.getInt(CREATE_KEY);
    mRestart = savedInstanceState.getInt(RESTART_KEY);
    mStart = savedInstanceState.getInt(START_KEY);
    mResume = savedInstanceState.getInt(RESUME_KEY);
 }
