方向更改时保存StreetViewFragment的状态

@Override
public void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    // 在这里保存StreetViewFragment的状态
    outState.putParcelable("streetViewPanoramaOptions", mStreetViewPanorama.getPanoramaOptions());
}

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    // 恢复StreetViewFragment的状态
    if (savedInstanceState != null) {
        StreetViewPanoramaOptions options = savedInstanceState.getParcelable("streetViewPanoramaOptions");
        mStreetViewPanorama.setPanoramaOptions(options);
    }
}
