我写了以下代码,返回我当前的位置地址.但是只有手动打开我的Wifi才能获得这些值.但我想打开Gps并从GPS获取我的地址,而不是从Wifi.有人请告诉我这段代码中要修改的是什么.以下是用于查找当前地址的代码.提前致谢.

public String myloc()
{ 
    criteria = new Criteria();
    criteria.setAccuracy(Criteria.ACCURACY_FINE);
    criteria.setAltitudeRequired(false);
    criteria.setBearingRequired(false);
    criteria.setCostAllowed(true);
    criteria.setPowerRequirement(Criteria.POWER_LOW);

    locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
    String provider = locationManager.getBestProvider(criteria, true);

    // Update the GUI with the last known 
    Location location = locationManager.getLastKnownLocation(provider);

    if(location!=null)
    {
        double lat = location.getLatitude();
        double lng = location.getLongitude();
        latLongString = "Lat:" + lat + "\nLong:" + lng;

        Geocoder gc = new Geocoder(this, Locale.getDefault());
        try
        {
            List<Address> addresses = gc.getFromLocation(lat, lng, 1);
            StringBuilder sb = new StringBuilder();
            if (addresses.size() > 0) 
            {
              Address address = …
