Android——onSaveInstanceState()

覆盖onSaveInstanceState方法，并在onCreate中检测savedInstanceState和获取保存的值

@Override  protected void onSaveInstanceState(Bundle outState) {       outState.putInt("currentposition", videoView.getCurrentPosition());      super.onSaveInstanceState(outState);  }  

public void onCreate(Bundle savedInstanceState) {      super.onCreate(savedInstanceState);      setContentView(R.layout.main);       initView();      if (savedInstanceState != null              && savedInstanceState.getInt("currentposition") != 0) {          videoView.seekTo(savedInstanceState.getInt("currentposition"));      }  }
