java - 如何在 fragment 的两个不同类中发送 Intent

Question

我有一个通过ntent发送的变量，并发送到两个不同的类，如何？ 所以我的 Intent 是这样的:

    case 0:
position = new LatLng (-8.447159, 112.651799);
args.putParcelable ("place_position", position);
a = new Intent (getActivity (), MapsMenu.class);
a.putExtra ("lat", args);
a.putExtra ("post", "cave");
a.putExtra ("location", "South Beach Goa China in Malang");
break;

键'post'发送到A类，而键'location'和'lat'发送到B类，我使用actionsherlock的 fragment ，对于变量成功发送到B类，而对于A类没有出现，源代码如下:

public class A extends SherlockListFragment {
    ListView list;
    List<HashMap<String, String>> aList = new ArrayList<HashMap<String, String>>();
    ImageView imDetail;
    String pos;
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                    Bundle savedInstanceState) {
            // TODO Auto-generated method stub
            Intent in = getActivity().getIntent();
            pos = (String) in.getStringExtra("post");
            return super.onCreateView(inflater, container, savedInstanceState);
    }

这是 B 级:

public class B extends SherlockMapFragment {
String title;
private GoogleMap map;
LatLng LAT = null;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View root = super.onCreateView(inflater, container, savedInstanceState);
    map = getMap();
    Bundle bundle = getActivity().getIntent().getParcelableExtra("lat");
    Intent in = getActivity().getIntent();
    title = (String) in.getStringExtra("location");
    LAT = bundle.getParcelable("place_position");

    LoadMaps(LAT, title);
    return root;
}

我错过了什么吗？

您将两个项目放入 Intent 中，分别称为“post”和“location”。但您搜索“pos”和“lokasi”。我认为这就是类(class)找不到您的 Intent 项目的原因。
