Hello mates,
I've got a serious problem with my GPS on my Nexus One: I wrote a kind of hello world with GPS, but the Toast that should be displayed isn't :(
I don't know what I'm doing wrong...maybe you could help me getting this work. Here's my code:
package gps.test;
import android.app.Activity;
import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.widget.Toast;
public class GPS extends Activity {
private LocationManager lm;
private LocationListener locationListener;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// ---use the LocationManager class to obtain GPS locations---
lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locationListener = new MyLocationListener();
lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 100, 1,
locationListener);
}
private class MyLocationListener implements LocationListener {
@Override
public void onLocationChanged(Location loc) {
if (loc != null) {
Toast.makeText(
getBaseContext(),
"Location changed : Lat: " + loc.getLatitude()
+ " Lng: " + loc.getLongitude(),
Toast.LENGTH_SHORT).show();
}
}
@Override
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub
}
}
}
Theoretically there should be a new toast every 100 milliseconds, shouldn't it? Or at least, when I change my position by one meter!?
I've no idea why it doesn't. I must admit I'm new to the topic, maybe I've missed something?
It would be great if you could give me a hint :)
nice greetings,
poeschlorn
