android – 在onCreate中检查savedInstanceState是否为null是判断设备是否已旋转的好方法？

private void loadPhotos() {
    final Object data = getLastNonConfigurationInstance();

    // The activity is starTing for the first time,load the photos from Flickr
    if (data == null) {
        mTask = new GetPhotoListTask().execute(mCurrentPagE);
    } else {
        // The activity was destroyed/created automatically,populate the grid
        // of photos with the images loaded by the prevIoUs activity
        final LoadedPhoto[] photos = (LoadedPhoto[]) data;
        for (LoadedPhoto photo : photos) {
            addPhoto(photo);
        }
    }
}

当我懒得这样做时,我只是禁用在方向更改时重新创建活动.如How do I disable orientation change on Android?所述
