I'm trying do a map in my app and that there will be a default marker here is the google maps activity xml I have tried countless time to make the marker appear but i just doesn't see it, i checked few threads here but nothing helped.
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:map="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.nir.nestleapp.GoogleMapsActivity"
map:cameraBearing="0"
map:cameraTargetLat="31.926597"
map:cameraTargetLng="34.800077"
map:cameraTilt="30"
map:cameraZoom="17"
/>
this is the java googlemaps activity which im trying to put the marker on:

}

mMap.addMarker(new MarkerOptions()
.position(nessziona)
.title("Hello world"));
mMap.moveCamera((CameraUpdateFactory.newLatLng(nessziona)));
}
}
MarkerOptions options = new MarkerOptions();
// Setting the position of the marker
// Set your multiple driver latitude and langitude below
options.position(CURRENT_LOCATION);
//Markers from drawable
options.icon(BitmapDescriptorFactory.fromResource(R.drawable.ambulance));
//For custom marker
options.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_RED))
options.title("Driver 1");
options.snippet("Driver-1");
mMap.addMarker(options);
Hope this helps you. If you have any issue please feel free to ask. Happy to help you :) :)
Try to use an icon for your marker!
Map.addMarker(new MarkerOptions()
.position(nessziona)
.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_RED))
.title("Hello world"));
Explanation:
This line
.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_RED))
will add an icon for your marker, a default red color icon.
refer to this link , for more info
Your code seems correct, so first check logs(may be map-key create some problem) and add this one in your code also..
@Override
public void onMapReady(GoogleMap googleMap) {
LatLng nessziona=new LatLng(31.926597,34.800077);
mMap = googleMap;
mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
mMap.addMarker(new MarkerOptions()
.position(nessziona)
.title("Hello world"));
mMap.moveCamera((CameraUpdateFactory.newLatLng(nessziona,17f)));
}
xml:
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:map="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.nir.nestleapp.GoogleMapsActivity"
/>
In my project I have this and it work :
@Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
BitmapDescriptor markerCustomIcon = BitmapDescriptorFactory.fromResource(R.drawable.trash_recyclebin_empty_closed);
BitmapDescriptor markerDefaultIcon = BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_VIOLET);
List<Marker> markersList = new ArrayList<Marker>();
for (int i = 0; i < pgoList.size(); i++) {
LatLng pos = new LatLng(pgoList.get(i).location.lat, pgoList.get(i).location.lon);
MarkerOptions marker = new MarkerOptions()
.position(pos)
.title(pgoList.get(i).address.full)
.icon(markerCustomIcon != null ? markerCustomIcon : markerDefaultIcon);
mMap.addMarker(marker);
markersList.add( mMap.addMarker(marker));
}
builder = new LatLngBounds.Builder();
for (Marker m : markersList) {
builder.include(m.getPosition());
}
int padding = 0;
LatLngBounds bounds = builder.build();
cu = CameraUpdateFactory.newLatLngBounds(bounds, padding);
mMap.setOnMapLoadedCallback(new GoogleMap.OnMapLoadedCallback() {
@Override
public void onMapLoaded() {
mMap.animateCamera(cu);
}
});
