實現並覆蓋了onSaveInstanceState方法：

[java] view plaincopy

1. @Override
2. protected void onSaveInstanceState(Bundle outState) {
3. // TODO Auto-generated method stub
4. outState.putInt("currentposition", videoView.getCurrentPosition());
5. Log.v("tag", "onSaveInstanceState");
6. super.onSaveInstanceState(outState);
7. }

2. /** Called when the activity is first created. */
3. @Override
4. public void onCreate(Bundle savedInstanceState) {
5. super.onCreate(savedInstanceState);
6. setContentView(R.layout.main);
7. Log.v("tag", "onCreate");
9. if (videoView == null) {
10. videoView = (VideoView) this.findViewById(R.id.myvideo);
11. MediaController controller = new MediaController(this);
12. videoView.setMediaController(controller);
13. videoView.setVideoPath(VIDEO_PATH);
14. videoView.requestFocus();
15. }
17. if (savedInstanceState != null
18. && savedInstanceState.getInt("currentposition") != 0) {
20. videoView.seekTo(savedInstanceState.getInt("currentposition"));
21. }
22. videoView.start();
24. }

onCreate方法中的參數savedInstanceState就是保存的Activity一些狀態。

[java] view plaincopy

1. savedInstanceState.getInt("currentposition")

獲取視頻播放時間。

紅色代碼是將當前video的播放時間存儲在Bundle中。

用onSaveInstanceState()方法保存Activity狀態
