Hi Andrea, I assume you mean the listaCoordinateCittaUtente list doesn't have any data after this call? This is the point of an asynchronous call, you can't predict how long the call will take to come back from the server, so you actually need to design your app to use the data only once it is completed. It looks like you sortof do that with map.addOverlay, where you're doing something to your map is once the call comes back; you need to consider the list in the same way. In this case, it won't have the complete result until onSuccess has been called nCicli times.
Also, if there really are many addresses, you would be much better off making your RPC call take the entire list at once. For one, there are only two connections allowed at a time, so making many calls will quickly cause a bottleneck - one call will be much more efficient than many. For two, I'm assuming you actually want to associate these returned points with their addresses. There is no guarantee of the order that onSuccess will be called with the return values, so even once it is completely filled, lista... list won't be in the same order as the address array. Finally, with one call you'll actually know for sure when the operation is done - the single call of onSuccess. jk On Mar 29, 9:39 am, Andrea <[email protected]> wrote: > I have the method getAddress() that take in input an array of cities. > For each city I use the Asyncronous method getLatLng() that return me > the coordinates and I save them in an ArrayList called > listaCoordinateCittaUtente. > But when I use the ArrayList after the call of the method getAddress() > it is empty. > I tried to resolve this problem with the Timer class but it isn't the > better solution. > How can I resolve this problem??? > > public void getAddress(String address[]){ > final int nCicli=address.length; > > for (int i = 0; i < nCicli; i++) { > final String nomeCitta=address[i]; > geocoder.getLatLng(nomeCitta, new LatLngCallback(){ > public void onFailure(){ > Window.alert(nomeCitta + " non esiste"); > } > public void onSuccess(LatLng point){ > listaCoordinateCittaUtente.add(point); > map.addOverlay(new Marker(point)); > map.setCenter(point); > } > }); > } > } -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
