Question

I want to build an app which will display restaurants stored in a database (name, lat, long etc…) on a map within certain radius from the user. The user can then click on a particular restaurant to view more information or add a review about that restaurant. I know how to fetch the name of restaurants from the database using JSON and PHP and display them in a list view. But I want to be able to display them on a map. Could someone please point me in the correct direction on how to get this done.

Answer 1

Assuming that you have a list of Restaurant objects that you can build from the data off your database:

private void addMarkers(List<Restaurant> restaurants){
    for(Restaurant res : restaurants){
        MarkerOptions options = new MarkerOptions();
        options.position(new LatLng(res.getLatitude(), res.getLongitude()));
        options.title(res.getName());
        options.snippet(tagsnap.getAddress());
        getMap().addMarker(options);
    }
}

Call this with something like:

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
    ...
    ...
    List<Restaurant> restaurants = databaseHelper.fetchAllRecordsAsRestaurantList();
    addMarkers(restaurants);
}
