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> {
GoogleMap mMap;
double myLatitude = 0;
double myLongitude = 0;

my myItem class to get info for the markers:

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;
}
#Override

// TODO Auto-generated method stub
return mPosition;

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

Async task not doing anything

I have created a infowindow for a marker and trying to set the address of a particular location by tapping on it but its not doing anything. Where am I making mistake?

anchor_address = (TextView) view.findViewById(R.id.address_a);
LatLng latlng = marker.getPosition();
AsyncTask<LatLng, Void, String> mytask = new AsyncTask<LatLng, Void, String>() {

anchor_name.setText("Ravi");
}
};
mytask.execute(latlng);
//anchor_address.setText(getParticularLocationAddress(latlng));
return view;

});
getParticularLocationAddress method is given as
public String getParticularLocationAddress(LatLng latlng) {
double longitude = latlng.longitude;
double latitude = latlng.latitude;
String marker_address = null;
try {

marker_address = addresses.get(0).getAddressLine(0) + ", "
+ addresses.get(0).getAddressLine(1);
} else {
marker_address = "Can't resolve";
}
} catch (Exception e) {
e.printStackTrace();

How to add multiple markers on a google map parsed from json array?

I have written a program in which on button click i am getting the nearby atms from json . This is the link
https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=19.052696,72.8713694&radius=1000&types=atm&sensor=true&key=AIzaSyA8szrI9Ue4EwyUwTgz7Nk0c39qMal0pN4

How do i achieve the above , can anyone suggest me ?
Thanks

You have written the method as,
private void moveAtmMap(Double amtLatitude,Double atmLongitude){
fragment.getMap().clear();
...
}
so every time this method will be called, it will clear all previous markers and you will end up having only the last marker.
Edit
for (int i = 0 ; i < urlDetails.length(); i++){
JSONObject json = urlDetails.getJSONObject(i);
String geometry = json.getString(GOEMETRY);
String vicinity = json.getString(VICINITY);
JSONObject jsonGeometry = new JSONObject(geometry);
String geoLocation = jsonGeometry.getString(LOCATION);
JSONObject jsonLatLng = new JSONObject(geoLocation);
double atmLat = jsonLatLng.getDouble(LATITUDE);
double atmLong = jsonLatLng.getDouble(LONGITUDE);
String atmName = json.getString(ATM_NAME);
runOnUiThread(new Runnable() {
#Override
public void run() {
moveAtmMap(atmLat, atmLong, atmName, vicinity, geometry);
}
});
}
and change method like,
private void moveAtmMap(Double amtLatitude,Double atmLongitude, String name, String vicinity, String geometry)
If you want to clear markers from previous web service hit, then do it before you start adding markers for new service hit, like before the for loop.

Remove this line from the method moveAtmMap:
fragment.getMap().clear();
For the first time, write it before for loop in onResponse.

Try this simple code,
for(int i=0;i<jsonArray.length();i++){
MarkerOptions markerOptions;
markerOptions = new MarkerOptions().position(new LatLng(lattitude,
longitude)
).title("Title").snippet("This is snippet");
markerOptions.icon(BitmapDescriptorFactory.fromResource(R.drawable.marker_icon));
marker = googleMap.addMarker(markerOptions);
}
Just replace lattitude,longitude with your values.
If you want to have instance of each marker,then you can put each "marker" object into hashmap with key as marker id. Let me know your feedback.
Note: remove this line - fragment.getMap().clear(); because it will clear map everytime when compiler comes into loop and it will take only last object. this is what happenng right now.

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:

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.
