Ich baue App, die zurückgelegte Strecke verfolgt. Im Moment habe ich Probleme, die Koordinaten anzuzeigen. Der Code wird ausgeführt, aber die Entfernung, die ich eingestellt habe, um die Koordinaten anzuzeigen, wenn auf Start geklickt wird, zeigt 0,00 an, wenn auf geklickt wird.GPS-Koordinaten werden nicht aktualisiert
public class MainActivity extends Activity {
private Button historyButton, startButton, stopButton;
private TextView Distance;
double currentDistance;
private SensorManager sensorManager;
private Chronometer TimeRan;
private LocationManager mLocManager;
private LocationListener location;
double longitude, latitude;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//Initializing all buttons and textviews
historyButton = (Button) findViewById(R.id.History);
startButton = (Button) findViewById(R.id.Start);
stopButton = (Button) findViewById(R.id.Stop);
Distance = (TextView) findViewById(R.id.Distance);
TimeRan = (Chronometer) findViewById(R.id.Time_Spent);
mLocManager = (LocationManager) getSystemService(LOCATION_SERVICE);
location = new LocationListener() {
@Override
public void onLocationChanged(Location location) {
currentDistance += .01;
Distance.append("/n " + location.getLongitude() + " " + location.getLatitude());
}
@Override

,100);
}
return;
}
//Request update every minute or 16 meters
startButton.setOnClickListener(new View.OnClickListener() {
@Override
