I want to add multiple markers in my map, but I don't know the way.
At the moment, I'm using this, and it works correctly:
Marker m1 = googleMap.addMarker(new MarkerOptions()
.position(new LatLng(38.609556, -1.139637))
.anchor(0.5f, 0.5f)
.title("Title1")
.snippet("Snippet1")
.icon(BitmapDescriptorFactory.fromResource(R.drawable.logo1)));
Marker m2 = googleMap.addMarker(new MarkerOptions()
.position(new LatLng(40.4272414,-3.7020037))
.anchor(0.5f, 0.5f)
.title("Title2")
.snippet("Snippet2")
.icon(BitmapDescriptorFactory.fromResource(R.drawable.logo2)));
Marker m3 = googleMap.addMarker(new MarkerOptions()
.position(new LatLng(43.2568193,-2.9225534))
.anchor(0.5f, 0.5f)
.title("Title3")
.snippet("Snippet3")
.icon(BitmapDescriptorFactory.fromResource(R.drawable.logo3)));
But the problem comes when I want to add 300 markers in my map. And doing it one by one is very annoying.
Is there any way to read markers from array or anything?
Another question: could I read markers from external file, so I can add or update markers without touching app code?
ArrayList<MarkerData> markersArray = new ArrayList<MarkerData>();
for(int i = 0 ; i < markersArray.size() ; i++) {
createMarker(markersArray.get(i).getLatitude(), markersArray.get(i).getLongitude(), markersArray.get(i).getTitle(), markersArray.get(i).getSnippet(), markersArray.get(i).getIconResID());
}
protected Marker createMarker(double latitude, double longitude, String title, String snippet, int iconResID) {
return googleMap.addMarker(new MarkerOptions()
.position(new LatLng(latitude, longitude))
.anchor(0.5f, 0.5f)
.title(title)
.snippet(snippet)
.icon(BitmapDescriptorFactory.fromResource(iconResID)));
}
