How do I pass dynamic data to a custom info window adapter in android?
I am trying to pass dynamic data (text and graphics plots) to a custom window adapter, but I get the same data for all markers, do I need different text and different images for my respective markers? I've tried the code below.
CustomInfoWindowAdapter.class
public class CustomInfoWindowAdapter implements InfoWindowAdapter {
private View v;
String selectedPath;
LatLng latLng;
String addtext;
Context context;
CustomInfoWindowAdapter(Context context, String addtext, String selectedPath, LatLng latLng) {
// TODO Auto-generated constructor stub
this.selectedPath = selectedPath;
this.latLng = latLng;
this.addtext = addtext;
this.context=context;
}
@Override
public View getInfoContents(Marker marker) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService( Context.LAYOUT_INFLATER_SERVICE );
v = inflater.inflate(R.layout.infowindow,
null);
ImageView icon = (ImageView) v.findViewById(R.id.icon);
// set some bitmap to the imageview
if (selectedPath != "") {
Log.d("Selectedpath", "sekectedpath" + selectedPath);
icon.setImageURI(Uri.parse(selectedPath));
}
TextView txt = (TextView) v.findViewById(R.id.textView1);
txt.setText(addtext);
return v;
}
@Override
public View getInfoWindow(Marker marker) {
// TODO Auto-generated method stub
return null;
}
}
and i called CustomInfoWindowAdapter for my activity like below
googleMap.setInfoWindowAdapter(new MyInfoWindowAdapter(addtext, selectedPath, latLng));

Add markers with information related to her. and when you click on a specific InfoWindow, you will get the specific marker data in the getInfoContents (Marker) method.
public class MainActivity extends AbstractMapActivity implements
OnMapReadyCallback, OnInfoWindowClickListener {
private boolean needsInit=false;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (readyToGo()) {
setContentView(R.layout.activity_main);
MapFragment mapFrag=
(MapFragment)getFragmentManager().findFragmentById(R.id.map);
if (savedInstanceState == null) {
needsInit=true;
}
mapFrag.getMapAsync(this);
}
}
@Override
public void onMapReady(final GoogleMap map) {
if (needsInit) {
CameraUpdate center=
CameraUpdateFactory.newLatLng(new LatLng(40.76793169992044,
-73.98180484771729));
CameraUpdate zoom=CameraUpdateFactory.zoomTo(15);
map.moveCamera(center);
map.animateCamera(zoom);
}
map.addMarker(new MarkerOptions()
.position(new LatLng(37.7750, 122.4183))
.title("San Francisco")
.snippet("Population: 776733"));
map.addMarker(new MarkerOptions()
.position(new LatLng(37.7750, 122.4183))
.title("San Francisco")
.snippet("Population: 776733"));
map.setInfoWindowAdapter(new PopupAdapter(getLayoutInflater()));
map.setOnInfoWindowClickListener(this);
}
@Override
public void onInfoWindowClick(Marker marker) {
Toast.makeText(this, marker.getTitle(), Toast.LENGTH_LONG).show();
}
private void addMarker(GoogleMap map, double lat, double lon,
int title, int snippet) {
map.addMarker(new MarkerOptions().position(new LatLng(lat, lon))
.title(getString(title))
.snippet(getString(snippet)));
}
}
