Android 中 onSaveInstanceState()使用方法详解
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"));
}
}
