How to get the current data of the marker that is in array list?

I am currently working with the google map. I already show the markers and the title and snippet of the marker.
Now my problem is when I click the info window it will be redirected to a new activity and get the data of the marker that was clicked. Here is my code:
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//stop location updates when Activity is no longer active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;
}
});
}
I'm using Android Volley and the array is on the Stringrequest. How can I get the data of the marker that was clicked on info window?
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);
}

Intent intent = new Intent(getActivity(), InfoWindowActivity.class);
intent.putExtra("snippet", snippet);
intent.putExtra("id", id)
... //put all your info here
startActivity(intent);
Access that data on next activity for example in onCreate or wherever you need it.
String snippet = getIntent().getStringExtra("snippet");
int id = getIntent().getIntExtra("id");
...//get all your info here
Is it what you were looking for? Question is not completely clear..

Wrong value for marker text passed to custom view

I am developing an android application which displays a map. When it loads, it displays some addresses and sets markers for them.
When I click on any marker it should display a value in a custom view. But the custom text which is received from a json parser, gets a null value. When I click on the marker again, it sets correct value.
When I click on second marker it display 1st marker value. When I click on 2nd marker again it displays correct value. This process continues
Here's my code:
private class GeocoderTask extends AsyncTask<String, Void, List<Address>>{
private Context mainContxt;
Geocoder geocoder;
public GeocoderTask(Context con){
mainContxt=con;
}
#Override
protected List<Address> doInBackground(String... locationName) {
Geocoder geocoder = new Geocoder(mainContxt);
List<Address> addresses = null;
try {
addresses = geocoder.getFromLocationName(locationName[0],1);
} catch (IOException e) {
e.printStackTrace();
}
return addresses;
}
#Override
protected void onPostExecute(List<Address> addresses) {
for(int i=0;i<addresses.size();i++){
Address address = (Address) addresses.get(i);
latLng = new LatLng(address.getLatitude(), address.getLongitude());

Help me friends ...thx in advance

Create a constructor for LoadSingleProperty
class LoadSingleProperty extends AsyncTask<String, String, String> {
Marker mMarker;
public LoadSingleProperty(Marker marker){
mMarker = marker;
}
.
.
.
}
and pass your marker object to it.
new LoadSingleProperty(marker_address).execute();
Once parsing is done set your marker's title using setTitle() method for the marker
mMarker.setTitle(c.getString(TAG_PROPERTY_TYPE));
where you currently do this
tempproperty_type=c.getString(TAG_PROPERTY_TYPE);
Don't forget to refresh your info window once title is reset
How to force refresh contents of the markerInfoWindow
You may also want to show some sort of a loading icon till this time since you're performing a network request.
EDIT:
In case you're using a custom titleview, get a reference to InfoWindowAdapter object before setting as a adapter to googleMap
InfoWindowAdapter infoWindowAdapter = new InfoWindowAdapter() {...
Once parsing is complete, get info window view for mMarker object by calling
infoWindowAdapter.getInfoWindow(mMarker);
Find your textView from the view obtained above and set its text. Then refresh your info window by calling showInfoWindow() to update the info window.
Also please refer this link.
The info window that is drawn is not a live view. The view is rendered
as an image (using View.draw(Canvas)) at the time it is returned. This
means that any subsequent changes to the view will not be reflected by
the info window on the map. To update the info window later (for
example, after an image has loaded), call showInfoWindow()

private class GeocoderTask extends AsyncTask<String, Void, List<Address>> {
private Context mainContxt;
Geocoder geocoder;
public GeocoderTask(Context con) {
mainContxt = con;
}
#Override
protected List<Address> doInBackground(String... locationName) {
Geocoder geocoder = new Geocoder(mainContxt);
List<Address> addresses = null;
try {
addresses = geocoder.getFromLocationName(locationName[0], 1);
} catch (IOException e) {
e.printStackTrace();
}
return addresses;
}
#Override
protected void onPostExecute(List<Address> addresses) {
for (int i = 0; i < addresses.size(); i++) {
Address address = (Address) addresses.get(i);
latLng = new LatLng(address.getLatitude(),
address.getLongitude());
String addressText = String.format(
"%s, %s",
address.getMaxAddressLineIndex() > 0 ? address
.getAddressLine(0) : "", address
.getCountryName());
markerOptions = new MarkerOptions();
markerOptions.position(latLng);
markerOptions.title(addressText);
if (i == 0) {
googleMap.animateCamera(CameraUpdateFactory.zoomBy(14),
2000, null);
googleMap.animateCamera(CameraUpdateFactory
.newLatLng(latLng));
}
googleMap.addMarker(markerOptions);
}
}
}
Then you write below code
googleMap.setOnMarkerClickListener(new OnMarkerClickListener() {
#Override
public boolean onMarkerClick(Marker marker_address) {
location = marker_address.getTitle();
new LoadSingleProperty().execute();
return false;
}
});
Take another customeWindowAdapter or else use the present one only and set that in onPostExecute() method of 'LoadSingleProperty' AsyncTask..
This will solve that.
ping here you have any queries

How can I pass parameters Latitude and Longitude in method doInBackground?

I tried to use reverse geocoding with AsyncTask but but the parameters of latitude and longitude that passes through the method doInBackground() are not happening correctly. any idea?
public class SitesAdapter extends ArrayAdapter<StackSite> {
public static Double lat;
public static Double lng;
#Override
public View getView(int pos, View convertView, ViewGroup parent){
...
lat = -1.80;
lng = -80.20;
...
}
public void start(){
new GetAddressTask(mContext).execute(lat, lng);
}
public static class GetAddressTask extends AsyncTask<Double, Void, String> {
//mContext
#Override
protected String doInBackground(Double... params) {
Geocoder gc = new Geocoder(mContext, Locale.getDefault());
List<Address> list = null;
String city = "";
double latitude = params[0];
double longitude = params[1];
try {
list = gc.getFromLocation(lat, lng, 1);
} catch (IOException e) {
e.printStackTrace();
}
if (list != null && list.size() > 0) {
Address address = list.get(0);
city = String.format("%s, %s", address.getAdminArea(), address.getCountryName());
}
return city;
}
#Override
protected void onPostExecute(String city) {
tituloTxt.setText(city);
}
}
}
error:
11-21 15:10:24.409: E/Trace(24502): error opening trace file: No such file or directory (2)

Well after so only had to do this to pass the coordinates. First add coordinate to constructor LatLng(double latitude, double longitude) and pass the parameters.
lat = -1.80;
lng = -80.20;
LatLng latlng = new LatLng(lat, lng);
new GetAddressTask(mContext).execute(lat, lng);
Then inside the doInbackground method get parameters.
public static class GetAddressTask extends AsyncTask<LatLng, Void, String> {
//mContext
#Override
protected String doInBackground(LatLng... params) {
Geocoder gc = new Geocoder(mContext, Locale.getDefault());
List<Address> list = null;
String city = "";
LatLng loc = params[0]; //Get all parameters: latitude and longitude
try {
list = gc.getFromLocation(loc.latitude, loc.longitude, 1); //get specific parameters
} catch (IOException e) {
e.printStackTrace();
}
if (list != null && list.size() > 0) {
Address address = list.get(0);
city = String.format("%s, %s", address.getAdminArea(), address.getCountryName());
return city;
}else{
return "City no found";
}
}
#Override
protected void onPostExecute(String city) {
tituloTxt.setText(city);
}
}

before calling execute method, u can just create a constructor ,in which you can initialize your class data members which can be further used in doInBackground(..).

Add two variables to your class and set them when you create async task, then use them in method. Simple.
public class GetAddressTask extends AsyncTask<String, Void, String> {
Context mContext;
float lat,lin;
public void setLat(int lat){...}
//rest of class
of course you can make everything static (fields and setters).
Edit.
If you are calling execute with some parameters, remember that your values have to be set before calling execute.

do this on Map object to add Marker
LatLng latLong = new LatLng(latitude, longitude);
googleMap.addMarker(new MarkerOptions()
.position(latLng)
.title("You"));
