如何获取数组列表中标记的当前数据？

Question

我目前正在使用谷歌地图。我已经显示了标记以及标记的标题和 sn-p。

现在我的问题是，当我单击信息窗口时，它将被重定向到一个新活动并获取所单击标记的数据。这是我的代码：

public class FindApartment extends Fragment implements OnMapReadyCallback,
    GoogleApiClient.ConnectionCallbacks,
    GoogleApiClient.OnConnectionFailedListener, LocationListener,GoogleMap.OnInfoWindowClickListener {


public static final String ID = "id";
public static final String VERIFICATION = "verification";
private static final String TAG_APARTMENTNAME = "apartmentName";
private static final String TAG_CATEGORY = "Category";
private static final String TAG_PRICE = "price_month";
public static final String LAT = "latt";
public static final String LNG = "longt";



MarkerOptions markerOptions = new MarkerOptions();
CameraPosition cameraPosition;
LatLng center, latLng;
String verification, apartmentname, category, price, id;


GoogleMap mGoogleMap;
LocationRequest mLocationRequest;
GoogleApiClient mGoogleApiClient;
Location mLastLocation;
Marker mCurrLocationMarker;
MapView mapView;

String tag_json_obj = "json_obj_req";

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_find_apartment, container, false);


    mapView = (MapView) rootView.findViewById(R.id.map1);
    mapView.onCreate(savedInstanceState);
    mapView.getMapAsync(this);
    mapView.onResume();


    return rootView;
}



@Override
public void onPause() {
    super.onPause();
    //stop location updates when Activity is no longer active
    if (mGoogleApiClient != null) {
        LocationServices.FusedLocationApi.removeLocationUpdates(mGoogleApiClient, this);
    }
}


@Override
public void onConnectionSuspended(int i) {

}

@Override
public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {

}

@Override

public void onLocationChanged(Location location) {
    mLastLocation = location;

    //Place current location marker
    LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());
    MarkerOptions myMarker = new MarkerOptions();
    myMarker.position(latLng);
    myMarker.title("me");
    myMarker.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_YELLOW));
    mCurrLocationMarker = mGoogleMap.addMarker(myMarker);

    //move map camera
    mGoogleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(latLng,17));
    getMarkers();

}


@Override
public void onMapReady(GoogleMap googleMap) {


    mGoogleMap=googleMap;
    mGoogleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
    mGoogleMap.setOnInfoWindowClickListener(this);


    if(mGoogleMap!= null){

        mGoogleMap.setInfoWindowAdapter(new GoogleMap.InfoWindowAdapter() {
            @Override
            public View getInfoWindow(Marker marker) {
                return null;
            }

            @Override
            public View getInfoContents(Marker marker) {
                View view = getLayoutInflater().inflate(R.layout.info_window, null);

                TextView textName = (TextView) view.findViewById(R.id.textName);
                TextView textViewPrice = (TextView) view.findViewById(R.id.textViewPrice);
                TextView detail = (TextView)view.findViewById(R.id.detail);

                LatLng ll = marker.getPosition();

                textName.setText(marker.getSnippet());
                textViewPrice.setText(marker.getTitle());
                detail.setText("click to see full detail");

                return view;
            }

        });




    }

我正在使用 Android Volley，并且该数组在 Stringrequest 上。如何获取信息窗口中被点击的标记的数据？

 private void addMarker(LatLng latLng, String category, final String price, final String id) {

    if (mCurrLocationMarker != null) {
        mCurrLocationMarker.remove();
    }

        MarkerOptions markerOptions = new MarkerOptions();
        markerOptions.position(latLng);
        markerOptions.title(price);
        markerOptions.snippet(category);
        markerOption(verification, markerOptions);


        mGoogleMap.addMarker(markerOptions);


    }


public void onInfoWindowClick(Marker marker) {
   id = marker.getId();
    String snippet = marker.getSnippet();

    Intent intent = new Intent(getActivity(), InfoWindowActivity.class);


    startActivity(intent);

}



private void markerOption(String verification, MarkerOptions markerOptions) {
    if(verification.contains("pending")) {
        markerOptions.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_RED));
    }
    else {
        markerOptions.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE));
    }
}


private void getMarkers() {
     String url = Server.URL2 + "markers.php";

    final HashMap<String, String> apartmentID = new HashMap<String, String>();
    StringRequest strReq = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {

        @Override
        public void onResponse(String response) {
            Log.e("Response: ", response.toString());

            try {
                JSONObject jObj = new JSONObject(response);
                String getObject = jObj.getString("apartments");


                JSONArray jsonArray = new JSONArray(getObject);

                for (int i = 0; i < jsonArray.length(); i++) {
                    JSONObject jsonObject = jsonArray.getJSONObject(i);

                    verification = jsonObject.getString(VERIFICATION);
                    apartmentname = jsonObject.getString(TAG_APARTMENTNAME);
                    category = jsonObject.getString(TAG_CATEGORY);
                    price = jsonObject.getString(TAG_PRICE);
                    id = jsonObject.getString("userID");

                    apartmentID.put(ID, id);

                    latLng = new LatLng(Double.parseDouble(jsonObject.getString(LAT)), Double.parseDouble(jsonObject.getString(LNG)));

                  //  Adds a data marker to show to google map
                    addMarker(latLng, category, price, id);



                }

            } catch (JSONException e) {
                // JSON error
                e.printStackTrace();
            }

        }
    }, new Response.ErrorListener() {

        @Override
        public void onErrorResponse(VolleyError error) {
            Toast.makeText(getContext(), error.getMessage(), Toast.LENGTH_LONG).show();
        }
    });


    AppController.getInstance().addToRequestQueue(strReq, tag_json_obj);
}

Answer 1

Intent intent = new Intent(getActivity(), InfoWindowActivity.class);
intent.putExtra("snippet", snippet);
intent.putExtra("id", id)
... //put all your info here 
startActivity(intent);

在下一个活动中访问该数据，例如在 onCreate 或任何您需要的地方。

String snippet = getIntent().getStringExtra("snippet");
int id = getIntent().getIntExtra("id");
...//get all your info here

这是你要找的吗？问题不完全清楚..
