Finally, update MainActivity's 'latitude' and 'longitude' fields with the correct coordinates when the user taps the Button.
public class GeolocationService extends Service {
private IBinder mBinder = new LocalBinder();
@Override

return mBinder;
}
public class LocalBinder extends Binder{
public GeolocationService getService(){
return GeolocationService.this;
}
}
//Client methods
public int getLatitude() { return getLat(); }
public int getLongitude() { return getLng(); }
}
public class MainActivity extends Activity {
private GeolocationService mGeolocationService;
int latitude;
int longitude;
boolean isBound;
Button updateLocationButton;
ServiceConnection serviceConnection = new ServiceConnection(){
public void onServiceConnected(ComponentName name, IBinder binder){
isBound = true;
GeolocationService.LocalBinder localBinder = (GeolocationService.LocalBinder) binder;
mGeolocationService = localBinder.getService();
}
public void onServiceDisconnected(ComponentName name){
isBound = false;
}
};
@Override

setContentView(R.layout.activity_main);
updateLocationButton = (Button) findViewById(R.id.update_button);
updateLocationButton.setOnClickListener(new View.OnClickListener() {

I'm out at the moment but I think you want to be using the two getter methods:
public int getLatitude() { return getLat(); }
public int getLongitude() { return getLng(); }
which are in GeolocationService
. Use those to set the latitude
and longitude
member variables of your activity.
Something like this inside onClick()
. There's no need to distinguish between lat & long with an if statement - there's only one button!
latitude = mGeolocationService.getLatitude();
longitude = mGeolocationService.getLongitude();
Try using the above inside onClick instead of where you have you if statement. Keep the isBound
if statement, though. As I said, I'm out at the moment but I'll get back to you with more when I am home again.
Steve.
