Google maps v2 marker using two snippet

Google maps v2 marker using two snippet - android

Good afternoon. Is it possible to add a few snippets of one marker? For Android version 2 of Google Maps
Marker melbourne = mMap.addMarker(new MarkerOptions()
.position(MELBOURNE)
.title("Melbourne")
.snippet("Population: 4,137,400"));
Here's my infowindow
class MyInfoWindowAdapter implements InfoWindowAdapter{
private final View myContentsView;
MyInfoWindowAdapter(){
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams((w*2)/3, LayoutParams.WRAP_CONTENT);
myContentsView = getLayoutInflater().inflate(R.layout.custom_info_contents, null);
myContentsView.setLayoutParams(lp);
}
public View getInfoContents(Marker marker) {
tvTitle = ((TextView)myContentsView.findViewById(R.id.title));
tvTitle.setText(marker.getTitle());
tvSnippet = ((TextView)myContentsView.findViewById(R.id.snippet));
tvSnippet.setText(marker.getSnippet());
return myContentsView;
}
public View getInfoWindow(Marker marker) {
// TODO Auto-generated method stub
return null;
}
}
I want to show different markers of different snippets, when necessary. How do I do this? And is it possible at all?
UPDATE:
You probably have not understood or wrongly I explained.
public void ParseQueryMap() {
ParseQuery query = new ParseQuery("MyObject");
query.findInBackground(new FindCallback() {
public void done(List<ParseObject> myObject, ParseException e) {
if (e == null) {
for ( int i = 0; i < myObject.size(); i++) {
commGet = myObject.get(i).getString("Comment");
bugGet = myObject.get(i).getObjectId();
geo1Dub = myObject.get(i).getParseGeoPoint("location").getLatitude();
geo2Dub = myObject.get(i).getParseGeoPoint("location").getLongitude();
Location aLocation = new Location("first");
aLocation.setLatitude(geo1Dub);
aLocation.setLongitude(geo2Dub);
Location bLocation = new Location("second");
bLocation.setLatitude(location.getLatitude());
bLocation.setLongitude(location.getLongitude());
int distance = (int)aLocation.distanceTo(bLocation);
if (distance<rad) {
myMap.addMarker(new MarkerOptions().position(new LatLng(geo1Dub,geo2Dub)).title(commGet).snippet(snippet)
.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_RED)));
} else {
}
}
} else {
Toast.makeText(MainActivity.this, "Error!", Toast.LENGTH_SHORT).show();
}
}
});
I want to get bugGet for each marker, the user bugGet not show, but when she clicks on infowindow I could learn bugGet specific marker. "bugGet" it "id" each marker in my database. The user does not need it, and I need you.

Here is example, you can check the coordinates of the marker and after that decide what infoWindow you want to show.
map.setInfoWindowAdapter(new InfoWindowAdapter() {
// Use default InfoWindow frame
#Override
public View getInfoWindow(Marker args) {
return null;
}
// Defines the contents of the InfoWindow
#Override
public View getInfoContents(Marker args) {
// Getting view from the layout file info_window_layout
View v = getLayoutInflater().inflate(R.layout.info_window_layout, null);
// Getting the position from the marker
clickMarkerLatLng = args.getPosition();
TextView title = (TextView) v.findViewById(R.id.tvTitle);
title.setText(args.getTitle());
map.setOnInfoWindowClickListener(new OnInfoWindowClickListener() {
public void onInfoWindowClick(Marker marker)
{
if (SGTasksListAppObj.getInstance().currentUserLocation!=null)
{
if (String.valueOf(SGTasksListAppObj.getInstance().currentUserLocation.getLatitude()).substring(0, 8).contains(String.valueOf(clickMarkerLatLng.latitude).substring(0, 8)) &&
String.valueOf(SGTasksListAppObj.getInstance().currentUserLocation.getLongitude()).substring(0, 8).contains(String.valueOf(clickMarkerLatLng.longitude).substring(0, 8)))
{
Toast.makeText(getApplicationContext(), "This your current location, navigation is not needed.", Toast.LENGTH_SHORT).show();
}
else
{
FlurryAgent.onEvent("Start navigation window was clicked from daily map");
tasksRepository = SGTasksListAppObj.getInstance().tasksRepository.getTasksRepository();
for (Task tmptask : tasksRepository)
{
String tempTaskLat = String.valueOf(tmptask.getLatitude());
String tempTaskLng = String.valueOf(tmptask.getLongtitude());
Log.d(TAG, String.valueOf(tmptask.getLatitude())+","+String.valueOf(clickMarkerLatLng.latitude).substring(0, 8));
if (tempTaskLat.contains(String.valueOf(clickMarkerLatLng.latitude).substring(0, 8)) && tempTaskLng.contains(String.valueOf(clickMarkerLatLng.longitude).substring(0, 8)))
{
task = tmptask;
break;
}
}
Intent intent = new Intent(getApplicationContext() ,RoadDirectionsActivity.class);
intent.putExtra(TasksListActivity.KEY_ID, task.getId());
startActivity(intent);
}
}
else
{
Toast.makeText(getApplicationContext(), "Your current location could not be found,\nNavigation is not possible.", Toast.LENGTH_SHORT).show();
}
}
});
// Returning the view containing InfoWindow contents
return v;
}
});

In one of my projects I created a new class MarkerSnippet and added all information to this class, e.g.:
public class MarkerSnippet {
private String foo;
private String bar;
public MarkerSnippet(String foo, String bar) {
this.foo = foo;
this.bar = bar;
}
// getter and setter for foo and bar
}
Then I create an instance of MarkerSnippet for each marker and add it as a JSON string (since the snippet only accepts Strings) using GSON:
Gson gson = new Gson(); // remark: only one Gson instane is needed
String fooContent = "myFoo";
String barContent = "myBar";
String snippetString = gson.toJson(new MarkerSnippet(fooContent, barContent));
map.addMarker(
new MarkerOptions().position(position)
.title(title)
.snippet(snippetString)
);
Then in your InfoWindowAdapter you need to convert your JSON string to the MarkerSnippet and add only this part of the snippet to your view that you want to show.

google marker open activity when marker is clicked

I have created an app that shows the list of bar locations by a marker on a map taken from a database on firebase.
each bar has a list of beverages.
what I wish to happen is that when a marker is clicked a new activity will open with the name of the bar selected at the top of the new activity
What i wish to happen is that when the marker is clicked it will open a new activity
//Declaration list of venues
List<Venue> venueList;
//onCreate method
venueList = new ArrayList<>();
mVenues.push().setValue(marker);
//onMapsReady method, gets the venues into the map
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
mVenues.addListenerForSingleValueEvent(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
for (DataSnapshot s : dataSnapshot.getChildren()){
Venue venue = s.getValue(Venue.class);
venueList.add(venue);
for (int i = 0; i < venueList.size(); i++)
{
LatLng latLng = new LatLng(venue.venueLat,venue.venueLong);
if (mMap != null) {
marker = mMap.addMarker(new MarkerOptions()
.position(latLng).title(venue.venueName));
}
}
}
}
#Override
public void onCancelled(DatabaseError databaseError) {
}
});
//Marker Click Event
//CMarker click event to take user to purchase beverage
mMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener(){
public boolean onMarkerClick(Marker marker) {
String title = marker.getTitle();
{
for (int i = 0; i < venueList.size();) {
//getting the selected venue
Venue venue = venueList.get(i);
//creating an intent
Intent intent = new Intent(getApplicationContext(), viewbeverageActivity.class);
//putting venue name and id to intent
intent.putExtra(VENUE_ID, venue.getVenueId());
intent.putExtra(VENUE_NAME, venue.getVenueName());
//starting the activity with intent
startActivity(intent);
}
return false;
}
}
});
//Venue Class
package uk.ac.ferry_j2ulster.beerapp;
import com.google.firebase.database.IgnoreExtraProperties;
public class Venue {
private String venueId;
public String venueName;
private String venueType;
public double venueLat;
public double venueLong;
public Venue(){
}
public Venue(String venueId, String venueName, String venueType,double venueLat, double venueLong) {
this.venueId = venueId;
this.venueName = venueName;
this.venueType = venueType;
this.venueLat = venueLat;
this.venueLong = venueLong;
}
public String getVenueId() {
return venueId;
}
public String getVenueName() {
return venueName;
}
public String getVenueType() {
return venueType;
}
public double getVenueLong() { return venueLong;
}
public double getVenueLat() {return venueLat;
}
}
I hope to open a new activity with the bar that was selected as a title at the top
no errors, not sure how to start with this one

The problem is that you are using a loop to go through each Venue, and calling startActivity() for all venues.
Instead, define a HashMap that will map each Marker ID to a Venue ID:
Map<String, String> mMarkerMap = new HashMap<>();
Then, put an entry in the HashMap for each Marker:
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
for (DataSnapshot s : dataSnapshot.getChildren()){
Venue venue = s.getValue(Venue.class);
venueList.add(venue);
for (int i = 0; i < venueList.size(); i++)
{
LatLng latLng = new LatLng(venue.venueLat,venue.venueLong);
if (mMap != null) {
marker = mMap.addMarker(new MarkerOptions()
.position(latLng).title(venue.venueName));
//Added:
mMarkerMap.put(marker.getId(), venue.getVenueId());
}
}
}
}
Then, when the user taps a Marker, get the title and Venue ID from the Marker/HashMap, and send it to the new activity:
#Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
//...........
mMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
#Override
public boolean onMarkerClick(Marker marker) {
String venueID = mMarkerMap.get(marker.getId());
String venueName = marker.getTitle();
Intent intent = new Intent(MapActivity.this, NewActivity.class);
intent.putExtra(VENUE_NAME, venueName);
intent.putExtra(VENUE_ID, venueID);
startActivity(intent);
return false;
}
});
}
In the new activity, simply get the title and Venue ID Strings passed in:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_new);
String venueName = getIntent().getStringExtra(MapActivity.VENUE_NAME);
if (title != null) {
getSupportActionBar().setTitle(title);
}
String venueID = getIntent().getStringExtra(MapActivity.VENUE_ID);
if (venueID != null) {
//use venue ID to get the information about this venue
}
//.......
}

You need to pass venue information also to the activity :
#Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
//...........
mMap.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
#Override
public boolean onMarkerClick(Marker marker) {
String title = marker.getTitle();
Venue venue = NULL;
for(int i=0;i<venueList.size();i++)
{
if(venueList.get(i).getTitle().equal(title))
venue = venueList.get(i);
}
Intent intent = new Intent(MapActivity.this, NewActivity.class);
intent.putExtra("title", title);
intent.putExtra("venue",venue.toJSON());
startActivity(intent);
return false;
}
});
}
Make a toJSON() function in your venue class and also fromJSON() which will help you in sending venue data as well.

ClusterManager OnClusterClickListener not called

Good afternoon every one, I manage my google maps v2 with cluster manager(I'm using this library android-maps-utils) and I want to get the diffrence when a marker clicked and when a cluster manager clicked, But methodes doesn't called, So what going wrong in my code, I spent 10 days in this small problem, So Please Help.
HERE IT IS MY WHOLE CODE:
public class BigClusteringDemoActivity extends BaseDemoActivity implements ClusterManager.OnClusterClickListener,ClusterManager.OnClusterItemClickListener {
private ClusterManager<MyItem> mClusterManager;
#Override
protected void startDemo() {
getMap().moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(51.503186, -0.126446), 10));
mClusterManager = new ClusterManager<MyItem>(this, getMap());
getMap().setOnCameraChangeListener(mClusterManager);
try {
readItems();
} catch (JSONException e) {
Toast.makeText(this, "Problem reading list of markers.", Toast.LENGTH_LONG).show();
}
getMap().setOnMarkerClickListener(mClusterManager);
}
private void readItems() throws JSONException {
InputStream inputStream = getResources().openRawResource(R.raw.radar_search);
List<MyItem> items = new MyItemReader().read(inputStream);
for (int i = 0; i < 10; i++) {
double offset = i / 60d;
for (MyItem item : items) {
LatLng position = item.getPosition();
double lat = position.latitude + offset;
double lng = position.longitude + offset;
MyItem offsetItem = new MyItem(lat, lng);
mClusterManager.addItem(offsetItem);
}
}
}
#Override
public boolean onClusterClick(Cluster cluster) {
Log.d("cluster","clicked" + cluster.getItems());
return false;
}
#Override
public boolean onClusterItemClick(ClusterItem item) {
Log.d("cluster","clicked" + item.getPosition());
return false;
}
}

You have not connected your ClusterManager to the map with onClick
You have this one getMap().setOnCameraIdleListener(mClusterManager);
try adding these aswell
getMap().setOnMarkerClickListener(mClusterManager);
mClusterManager.setOnClusterClickListener(this);
mClusterManager.setOnClusterItemClickListener(this);`
This will use the implements for listeners you added.

I have managed to find sequence of ClusterManager initialization for click listeners finally work:
1) init maps
mMap = googleMap
2) init ClusterManager
mClusterManager = ClusterManager(requireContext(), mMap)
3) set Map OnMarkerClickListener
mMap.setOnMarkerClickListener(mClusterManager)
4) init ClusterManager
mClusterManager = ClusterManager(requireContext(), mMap)
5) set cluster click listeners
mClusterManager.setOnClusterItemClickListener {
println("CLUST ITEM CLICK")
return#setOnClusterItemClickListener false
}
mClusterManager.setOnClusterClickListener {
println("CLUST CLICK")
return#setOnClusterClickListener false
}
6) when you use your custom render init it now:
mClusterManager.renderer = CustomIconRenderer(requireContext(), mMap, mClusterManager)

Unable to add parse image to custom Google Map info window

I am trying to add an image I have in parse to a google map info window, I can add the image from resource but I am unable to load my existing parse image to the image view inside my infowindow. I have loaded the image from parse in other areas of my app, but it seems that the info window is out of scope. Is there a way to load this parse image inside my infowindow? I do not want to use a resource file because the images are different in parse. The 2 sections of my code are below:
class NearbyEventTask extends AsyncTask<String, Void, ArrayList<Item>>
{
Random r;
Context context;
public NearbyEventTask(Context context){
r = new Random();
this.context = context;
}
public LatLng getRandomLocation(Location center, double radius) {
// Convert radius from meters to degrees
double radiusInDegrees = radius / 111000;
double u = r.nextDouble();
double v = r.nextDouble();
double w = radiusInDegrees * Math.sqrt(u);
double t = 2 * Math.PI * v;
double lat = w * Math.cos(t);
double lon = w * Math.sin(t);
double new_lat = lat / Math.cos(center.getLongitude());
return new LatLng(new_lat + center.getLatitude(), lon + center.getLongitude());
}

CODE UPDATED: If you look at my NearbyEventTast class at the top, you can see how the code was implemented to get the data back from parse. I am trying to do the same thing by creating a new NearbyEventTast but I fail to load the correct image. It always shows the same image (I think its the first one in parse) and displays it for all objects instead of the corresponden image. Any idiea whats going on? Thank you!

As I am not much aware of Parse. But I have also face this issue to show a image from URL into info window.
First of all, the reason infowindow is not showing the downloaded image because MapFragment renders the view into a Canvas and then draws that. What you're seeing in the info window aren't the views you created, but a "picture" or "screenshot" of them. You basically need to call showInfoWindow() again on the Marker object, and that will re-render the Canvas and your image will now be visible.
Or you can use the Picasso Library to load the image. I am using the Picasso callback option in my app.
First you need to create a Class that will implements a Picasso Callback Interface and in the Constructor recieve a marker to call a show info window when image loads.
public static class MarkerCallback implements Callback {
private Marker marker;
public MarkerCallback(Marker marker) {
this.marker = marker;
}
#Override
public void onSuccess() {
if (marker != null && marker.isInfoWindowShown()) {
marker.hideInfoWindow();
marker.showInfoWindow();
}
}
#Override
public void onError() {
}
}
How to use it.
public View getInfoContents(Marker marker) {
View v = getActivity().getLayoutInflater().inflate(R.layout.maps_infowindow, null);
v.setLayoutParams(new LinearLayout.LayoutParams((int) (mapFragment.getView().getMeasuredWidth() * .9), LinearLayout.LayoutParams.WRAP_CONTENT));
((TextView) v.findViewById(R.id.title)).setText(marker.getTitle());
((TextView) v.findViewById(R.id.desc)).setText(marker.getSnippet());
ImageView markerIcon = (ImageView) v.findViewById(R.id.imageView5);
Picasso.with(MainActivity.this).load(imgUrl).into(markerIcon, new MarkerCallback(marker));
}
Hope this will help you.

Android Cluster manager icon depending on type

I'm working on a small app and have implemented Google Maps and Places api. Currently i'm able to see all my markers on the map and clustering working fine. I'm able to zoom in the clusters open up and able to see the markers. I have a spinner that has different types and once selected that type is passed to the places search string.
This is my maps code that includes the clustering:
public class MapsActivity extends FragmentActivity implements LocationListener,ClusterManager.OnClusterItemInfoWindowClickListener<MyItem> {

my myItem class to get info for the markers:

public class MyItem implements ClusterItem {
LatLng mPosition;
private String reference,placeTitle,snippet;
public MyItem(double lat, double lng,String val,String title, String snip) {
mPosition = new LatLng(lat, lng);
reference=val;
placeTitle=title;
snippet = snip;

public String getTitle() {
// TODO Auto-generated method stub
return placeTitle;
}
public String getSnippet() {
// TODO Auto-generated method stub
return snippet;
}
}
Currently only red markers are getting displayed but I was wondering if there is a way to have a different markers depending on the type selected from the spinner, For example if I select Hospital then the markers are shown as little hospital icons, if I select ATM, then a little ATM icon appears.
Any help will be appreciated.

Firstly you have to store all the info you need (at this situation just LatLng and marker icon) insite ClusterItem object.
public class MarkerItem implements ClusterItem {
private String title;
private String snippet;
private LatLng latLng;
private BitmapDescriptor icon;
public MarkerItem(MarkerOptions markerOptions) {
this.latLng = markerOptions.getPosition();
this.title = markerOptions.getTitle();
this.snippet = markerOptions.getSnippet();
this.icon = markerOptions.getIcon();
}
#Override
public LatLng getPosition() {
return latLng;
}
public String getTitle() {
return title;
}
public String getSnippet() {
return snippet;
}
public void setLatLng(LatLng latLng) {
this.latLng = latLng;
}
public BitmapDescriptor getIcon() {
return icon;
}
public void setIcon(BitmapDescriptor icon) {
this.icon = icon;
}
}
The next step would be to make cluster renderer show your icon instead of default maker icon. To achieve that, you need to extend DefaultClusterRenderer object:
public class ClusterRenderer extends DefaultClusterRenderer<MarkerItem> {
public ClusterRenderer(Context context, GoogleMap map, ClusterManager<MarkerItem> clusterManager) {
super(context, map, clusterManager);
clusterManager.setRenderer(this);
}
#Override
protected void onBeforeClusterItemRendered(MarkerItem markerItem, MarkerOptions markerOptions) {
if (markerItem.getIcon() != null) {
markerOptions.icon(markerItem.getIcon()); //Here you retrieve BitmapDescriptor from ClusterItem and set it as marker icon
}
markerOptions.visible(true);
}
}
Finally, you have to initialize the clusterRenderer and markerItems
ClusterManager clusterManager = new ClusterManager<>(context, googleMap);
ClusterRenderer clusterRenderer = new ClusterRenderer<>(activity, googleMap, clusterManager); // not needed to use clusterManager.setRenderer method since i made it in constructor
MarkerOptions markerOptions = new MarkerOptions()
.position(new LatLng(latitude, longitude))
.icon(BitmapDescriptorFactory.fromResource(R.drawable.your_resource_icon));
MarkerItem markerItem = new MarkerItem(markerOptions);
clusterManager.addItem(markerItem);
You can implement your own logic, which icon you want to pass to markerItem here.
EDIT
To pass different icons, you could create a separate method for that
Example:
public MarkerOptions getMarkerOptions(LatLng latLng, String title, String snippet, int iconRes) {
return new MarkerOptions()
.title(title)
.snippet(snippet)
.position(latLng)
.icon(BitmapDescriptorFactory.fromResource(iconRes));
}
EDIT 2
I updated MarkerItem class to suit your needs, replace your MyItem class with MarkerItem class. Add your items using this class and update it to suit your needs

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());
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);
}
googleMap.setOnMarkerClickListener(new OnMarkerClickListener() {
#Override
public boolean onMarkerClick(Marker marker_address) {
location=marker_address.getTitle();
Toast.makeText(getApplicationContext(),location, Toast.LENGTH_LONG).show();
new LoadSingleProperty().execute();
//new LoadImage().execute();
return false;
}
});
googleMap.setInfoWindowAdapter(new InfoWindowAdapter() {
#Override
public View getInfoWindow(Marker arg0) {
return null;
}
#Override
public View getInfoContents(Marker marker) {
View myContentView = getLayoutInflater().inflate(
R.layout.custom_marker, null);
tempnew_price=getPrice(temptotal_price+"" +email);
TextView tvTitle = ((TextView) myContentView
.findViewById(R.id.title));
// tvTitle.setText(location);
tvSnippet = ((TextView) myContentView
.findViewById(R.id.snippet));
ivProperty = ((ImageView) myContentView
.findViewById(R.id.image_property));
tvTitle.setText(tempcovered_area+ " "+tempnew_price+System.getProperty("line.separator")+templocation);
tvSnippet.setText("A "+ tempbedroom + " "+tempproperty_type);
// new LoadImage().execute();
ivProperty.setImageBitmap(bmp);
return myContentView;
}
});

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
