I am trying to render a custom InfoWindow with different values for each marker using MarkerCluster
This is what i try:
private final GoogleMap.InfoWindowAdapter mInfoWindowAdapter = new GoogleMap.InfoWindowAdapter() {
@Override
public View getInfoWindow(Marker marker) {
View window = null;
if(getActivity()!=null&&isAdded()){
window = getActivity().getLayoutInflater().inflate(R.layout.map_objective_overlay, null);
final CustomFontTextView nameTV = (CustomFontTextView) window.findViewById(R.id.nameTV);
if(clickedClusterItem!=null){
System.out.println("You clicked this: "+clickedClusterItem.getName());
}else{
System.out.println("The clicked cluster item was nulllll");
}
if (clickedCluster != null) {
for (Objective item : clickedCluster.getItems()) {
// Extract data from each item in the cluster as needed
if(item.getRemoteId().equals(clickedClusterItem.getRemoteId())){
nameTV.setText(clickedClusterItem.getName());
}
}
}
}
return window;
}
@Override
public View getInfoContents(Marker marker) {
return null;
}
};
private Objective clickedClusterItem;
private Cluster<Objective> clickedCluster;
@Override
public void onResume() {
super.onResume();
preferences = getActivity().getSharedPreferences(Constants.PREFS_NAME, Context.MODE_PRIVATE);
if (map == null) {
map = fragment.getMap();
mClusterManager = new ClusterManager<Objective>(getActivity(), map);
map.setOnCameraChangeListener(mClusterManager);
map.setOnMarkerClickListener(mClusterManager);
latitude = Double.parseDouble(preferences.getString(Constants.LATITUDE, "0"));
longitude = Double.parseDouble(preferences.getString(Constants.LONGITUDE, "0"));
map.addMarker(new MarkerOptions()
.position(new LatLng(latitude, longitude))
.title("Hello " + preferences.getString(Constants.TOURIST_NAME, "tourist"))
.snippet("You are here")
.icon(BitmapDescriptorFactory.fromResource(R.drawable.ic_check_in)));
map.setInfoWindowAdapter(mClusterManager.getMarkerManager());
//mClusterManager.setRenderer(new ObjectiveClusterRenderer(getActivity(), map, mClusterManager));
mClusterManager.getClusterMarkerCollection().setOnInfoWindowAdapter(mInfoWindowAdapter);
mClusterManager.getMarkerCollection().setOnInfoWindowAdapter(mInfoWindowAdapter);
map.setOnMarkerClickListener(mClusterManager);
mClusterManager.setOnClusterClickListener(new ClusterManager.OnClusterClickListener<Objective>() {
@Override
public boolean onClusterClick(Cluster<Objective> cluster) {
clickedCluster = cluster; // remember for use later in the Adapter
return false;
}
});
mClusterManager.setOnClusterItemClickListener(new ClusterManager.OnClusterItemClickListener<Objective>() {
@Override
public boolean onClusterItemClick(Objective item) {
clickedClusterItem = item;
return false;
}
});
And here i add the markers to the clustermanager:
public void setUpClusterer(List<Objective> objectivesList) {
map.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(latitude, longitude), 10));
addItems(objectivesList);
}
private void addItems(List<Objective> objectiveList) {
for (Objective anObjectiveList : objectiveList) {
Objective offsetItem = new Objective();
offsetItem.setRemoteId(anObjectiveList.getRemoteId());
offsetItem.setName(anObjectiveList.getName());
objectiveMap.put(offsetItem.getRemoteId(), offsetItem);
System.out.println("This is the remote ID: " + offsetItem.getRemoteId());
mClusterManager.addItem(offsetItem);
}
}
The layout for the InfoWindow is okay, but the content is null as clickedClusterItem and clickedCluster are always null...
Any hints as to what I might be doing wrong?
I saw some other answers that involved creating a Map with the marker and the corresponding object but I am not quite sure how to do that.
I did this in my app. Try this in your.
GoogleMap googleMap;
Double latitude;
Double longitude;
Marker mark;
MarkerOptions marker;
Bitmap bitmap;
String position, catName, activity;
ToggleButton listView, mapView;
Hashtable<Integer, String> markers;
ArrayList<HomeProperty> list = new ArrayList<HomeProperty>();
ArrayList<HomeProperty> newList;
ArrayList<HomeProperty> category = new ArrayList<HomeProperty>();
ArrayList<SearchProperty> searchList = new ArrayList<SearchProperty>();
ArrayList<HomeProperty> locationList = new ArrayList<HomeProperty>();
ProgressDialog dialog;
ImageLoader imageLoader;
@Override
protected void onCreate(Bundle savedInstanceState) {
// Introduction
super.onCreate(savedInstanceState);
setContentView(R.layout.map);
initilizeMap();
imageLoader = new ImageLoader(getApplicationContext());
markers = new Hashtable<Integer, String>();
listView = (ToggleButton) findViewById(R.id.listView);
mapView = (ToggleButton) findViewById(R.id.mapView);
listView.setOnCheckedChangeListener(this);
mapView.setOnCheckedChangeListener(this);
mapView.setChecked(true);
// setting the arraylist containing all data of events
ArrayData aData = (ArrayData) getIntent().getSerializableExtra("list");
position = getIntent().getStringExtra("position");
catName = getIntent().getStringExtra("catName");
activity = getIntent().getStringExtra("activity");
list = aData.getList();
ArrayData categoryData = (ArrayData) getIntent().getSerializableExtra(
"category");
category = categoryData.getList();
if (getIntent().hasExtra("searchData")) {
SearchData search = (SearchData) getIntent().getSerializableExtra(
"searchData");
searchList = search.getList();
} else {
searchList = new ArrayList<SearchProperty>();
}
newList = new ArrayList<HomeProperty>();
// for all categories
if (catName.equalsIgnoreCase("All")) {
newList.clear();
newList.addAll(list);
} else if (activity.equals("search")) {
newList.addAll(list);
}
// for single category
else {
for (int count = 0; count < list.size(); count++) {
if (list.get(count).getCategoryName().equals(catName)) {
newList.add(list.get(count));
}
}
}
// looping through All Transactions
for (int count = 0; count < newList.size(); count++) {
HomeProperty prop = new HomeProperty(newList.get(count).getLatitude(),
newList.get(count).getLongitude());
locationList.add(prop);
}
for (int count = 0; count < newList.size(); count++) {
marker = new MarkerOptions()
.position(
new LatLng(Double.parseDouble(list.get(count)
.getLatitude()), Double.parseDouble(newList
.get(count).getLongitude())))
.title(newList.get(count).getTitle())
.snippet(
new JSONMethods().SHORTIMAGEURL
+ newList.get(count).getImageDirectory()
+ "/thumb_" + newList.get(count).getImage());
googleMap.addMarker(marker);
CameraPosition cameraPosition = new CameraPosition.Builder()
.target(new LatLng(Double.parseDouble(newList.get(count)
.getLatitude()), Double.parseDouble(newList.get(count)
.getLongitude()))).zoom(12).build();
googleMap.animateCamera(CameraUpdateFactory
.newCameraPosition(cameraPosition));
googleMap.setInfoWindowAdapter(new CustomInfoWindowAdapter());
}
googleMap.getUiSettings().setZoomGesturesEnabled(true);
googleMap.getUiSettings().setCompassEnabled(true);
googleMap.getUiSettings().setMyLocationButtonEnabled(true);
googleMap.getUiSettings().setRotateGesturesEnabled(true);
}
// set action on home button click in action bar
@Override
public boolean onOptionsItemSelected(MenuItem item) {

switch (item.getItemId()) {
// case R.id.action_settings:
