    <p>Currently, I am working on GoogleMaps, but I have a problem. E.g when I</p> <p>lat: 22.422006 lng: 23.084095</p> <p>emulator toasts me like : </p> <p>lat: 2.2422006E13 lng: 2.3084095E7</p> <p>I read so many tutorials, and made exactly the same, but I can't handle this problem. </p> <p>Here is my code : </p> <pre><code> public class MainActivity extends MapActivity { public static final String TAG = "GoogleMapsActivity"; private MapView mapView; private LocationManager locationManager; Geocoder geocoder; Location location; LocationListener locationListener; CountDownTimer locationtimer; MapController mapController; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mapView = (MapView)findViewById(R.id.mapView); mapController = mapView.getController(); mapController.setZoom(16); mapView.setBuiltInZoomControls(true); readFromGPS(); } private void readFromGPS() { locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE); // Define a listener that responds to location updates locationListener = new LocationListener() { public void onLocationChanged(Location location) { // Called when a new location is found by the network location provider. Toast.makeText(getApplicationContext(), location.getLatitude()*1E6+"-"+location.getLongitude(), Toast.LENGTH_SHORT).show(); } public void onStatusChanged(String provider, int status, Bundle extras) {} public void onProviderEnabled(String provider) { Toast.makeText(getApplicationContext(), "GPS Enabled", Toast.LENGTH_SHORT).show(); } public void onProviderDisabled(String provider) { } }; locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,1000, 0, locationListener); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.activity_main, menu); return true; } @Override protected boolean isRouteDisplayed() { // TODO Auto-generated method stub return false; } } </code></pre>

    1. COIt looks like the code is giving exactly the expected results. Although perhaps you are being confused by the fact that in your toast message you are multiplying lat by 1e6 and are not doing the same for lon?

    2. COI think you're just seeing the result of the location.getLatitude() being converted to a String. Try creating doubles to hold the lat/long and assign the result of the gets to those variables.

    3. CO@ScottW : I multiplied by 1E6 to just see the mistake is from it or not. But it doesn't changed. So, you can think with or without it for both latitude and longitude..

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
