【参考方案1】:

您可以使用以下代码跟踪您的位置

public class GPSTracker extends Service implements LocationListener 

    private final Context mContext;

    // flag for GPS status
    public static boolean isGPSEnabled = false;

    // flag for network status
    public static boolean isNetworkEnabled = false;

    // flag for GPS status
    boolean canGetLocation = false;

    Location location; // location
    double latitude=0.0; // latitude
    double longitude=0.0; // longitude

    // The minimum distance to change Updates in meters
    private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 1; // 1 meters

    // The minimum time between updates in milliseconds
    private static final long MIN_TIME_BW_UPDATES = 30000; // 1 minute

    // Declaring a Location Manager
    protected LocationManager locationManager;

    public GPSTracker(Context context) 
        this.mContext = context;
        getLocation();
    

    public Location getLocation() 
        try 
            locationManager = (LocationManager) mContext
                    .getSystemService(LOCATION_SERVICE);

            // getting GPS status
            isGPSEnabled = locationManager
                    .isProviderEnabled(LocationManager.GPS_PROVIDER);

            // getting network status
            isNetworkEnabled = locationManager
                    .isProviderEnabled(LocationManager.NETWORK_PROVIDER);

            if (!isGPSEnabled || !isNetworkEnabled) 

             else 
                this.canGetLocation = true;
                // First get location from Network Provider
                if (isNetworkEnabled) 
                    locationManager.requestLocationUpdates(
                            LocationManager.NETWORK_PROVIDER,
                            MIN_TIME_BW_UPDATES,
