我有框架布局,我在其中显示片段,我如何显示谷歌地图它的 frame_layout。我下一个:

  1. 获取 API 密钥
  2. 添加谷歌播放服务库但我得到nullPointerExeption,也许有人知道如何使用它的好例子?car_waches.xml

片段类:

public class FragmentCarWashes extends SherlockFragment {
View v;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    GoogleMap map = ((SupportMapFragment) getFragmentManager().findFragmentById(R.id.mapFragment))
               .getMap();
    v = inflater.inflate(R.layout.fragment_car_washes, null);

    return v;
}
}

我不太熟悉 serlock 的东西,但我相信你需要使用SherlockMapFragment

编辑:

看看这个链接

SupportMapFragment 或 GoogleMap 为空
