He estado tratando de crear una aplicación de Android relacionada con el mapa, pero me di cuenta de que el onLocationChanged de mi aplicación no se había llamado, por lo tanto, el mapa siempre permanece en el área predeterminada (EE. UU.).onLocationChanged no se ha llamado
mi código:
public class MapMainActivity extends MapActivity
implements OnClickListener, LocationListener {
MapView mapView;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.map_main);
//reference
mapView = (MapView)findViewById(R.id.map_view);
mapView.setBuiltInZoomControls(true);
this.findViewById(R.id.btn_satellite).setOnClickListener(this);
this.findViewById(R.id.btn_street).setOnClickListener(this);
}//onCreate
@Override
protected void onResume() {
super.onResume();
Toast.makeText(this, "GPS tracking started",
Toast.LENGTH_SHORT).show();
// Start location updates; 5s/5m
LocationManager locManager = (LocationManager)getSystemService(
Context.LOCATION_SERVICE);
locManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,
5000, 0, this);
Criteria crit = new Criteria();
crit.setAccuracy(Criteria.ACCURACY_FINE);
String provider = locManager.getBestProvider(crit, true);
Location loc = locManager.getLastKnownLocation(provider);
}//onResume
@Override
protected void onPause() {
super.onPause();
Toast.makeText(this, "GPS tracking stopped",
Toast.LENGTH_SHORT).show();
LocationManager locManager = (LocationManager)getSystemService(
Context.LOCATION_SERVICE);
locManager.removeUpdates(this);
}//onPause
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(v == findViewById(R.id.btn_street))
{
mapView.setSatellite(false);
}//street view
else if (v == findViewById(R.id.btn_satellite))
{
mapView.setSatellite(true);
}
}//onClick
@Override
protected boolean isRouteDisplayed() {
// TODO Auto-generated method stub
return false;
}//isRouteDisplayed
@Override
public void onLocationChanged(Location location) {
// TODO Auto-generated method stub
double lat = location.getLatitude();
double lon = location.getLongitude();
TextView txtLat = (TextView)findViewById(R.id.txt_lat);
txtLat.setText(String.format("%.6f", lat));
TextView txtLon = (TextView)findViewById(R.id.txt_lon);
txtLon.setText(String.format("%.6f", lon));
MapView map = (MapView)findViewById(R.id.map_view);
map.getController().animateTo(new GeoPoint((int)(lat*1E6),//1000000),
(int)(lon*1E6)));
}//onLocationChanged
@Override
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
Toast.makeText(this, "GPS disabled",
Toast.LENGTH_SHORT).show();
}//onProviderDisabled
@Override
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
Toast.makeText(this, "GPS enabled",
Toast.LENGTH_SHORT).show();
}//onProviderEnabled
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub
}//onStatusChanged
}//class

¿cómo ha cambiado la ubicación? – freshDroid
er ... realmente no entiendo lo que quieres decir. pero, como no estoy en el estado, cuando ejecuto la aplicación no debería mostrar el mapa de estados. – Jovi
