当android中的Internet(wifi/DataPack)打开时，如何获取用户的位置

Question

我试图获得的位置只有当用户互联网是oN，而不是使用全球定位系统/网络提供商。

Answer 1

你要做的是使用LocationManager.NETWORK_PROVIDER而不是LocationManager.GPS_PROVIDER来获得这个职位。NETWORK_PROVIDER将在GSM或wifi上解析。显然，在关闭wifi的情况下，将使用GSM。请记住，使用蜂窝网络基本上可以精确到500米。

**有一些非常棒的信息和示例代码。**

在完成OnCreate()中的大部分代码之后，添加以下代码：

// Acquire a reference to the system Location Manager
LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);

// Define a listener that responds to location updates
LocationListener locationListener = new LocationListener() {
    public void onLocationChanged(Location location) {
      // Called when a new location is found by the network location provider.
      makeUseOfNewLocation(location);
    }

    public void onStatusChanged(String provider, int status, Bundle extras) {}

    public void onProviderEnabled(String provider) {}

    public void onProviderDisabled(String provider) {}
  };

// Register the listener with the Location Manager to receive location updates
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);

您还可以让您的活动实现LocationListener类，从而在您的活动中实现onLocationChanged()。

尝尝这个。

    public void getCurrentLocation() {

        if (mlocManager != null) {
            mlocManager .requestLocationUpdates(
                    LocationManager.NETWORK_PROVIDER, 0, 0, locListener );
            mlocManager .requestLocationUpdates(
                    LocationManager.GPS_PROVIDER, 0, 0, locListener );
        }

}

请尝试使用互联网获取当前位置。

public class CurrentLocation extends Activity {

TextView tv;
Geocoder geocoder;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_current_location);

    tv = (TextView) findViewById(R.id.textView1);
    geocoder = new Geocoder(this);

    // Acquire a reference to the system Location Manager
    LocationManager locationManager = (LocationManager) this
            .getSystemService(Context.LOCATION_SERVICE);

    // Define a listener that responds to location updates
    LocationListener locationListener = new LocationListener() {
        public void onLocationChanged(Location location) {
            // Called when a new location is found by the network location
            // provider.

            String text = String.format(
                    "Lat:\t %f\nLong:\t %f\nAlt:\t %f\nBearing:\t %f",
                    location.getLatitude(), location.getLongitude(),
                    location.getAltitude(), location.getBearing());
            tv.setText(text);

            try {


                List<Address> addressList = geocoder.getFromLocation(
                        location.getLatitude(), location.getLongitude(), 1);

                Log.d("Current", addressList.toString());
                if (addressList != null && addressList.size() > 0) {
                    Address address = addressList.get(0);
                    StringBuilder sb = new StringBuilder();

                    String address_own = addressList.get(0).getAddressLine(
                            0);
                    String city = addressList.get(0).getAddressLine(1);
                    // String country = addresses.get(0).getAddressLine(2);

                    Log.d("Address", address_own);
                    Log.d("City", city);
                    // Log.d("Country", country);

                    for (int i = 0; i < address.getMaxAddressLineIndex(); i++) {
                        sb.append(address.getAddressLine(i)).append("\n");
                    }

                    tv.append("\n" + address_own + ", " + city);
                }



            } catch (IOException e) {
                Log.e("LocateMe", "Could not get Geocoder data", e);
            }

        }

        public void onStatusChanged(String provider, int status,
                Bundle extras) {
        }

        public void onProviderEnabled(String provider) {
        }

        public void onProviderDisabled(String provider) {
        }
    };

    // Register the listener with the Location Manager to receive location
    // updates
    locationManager.requestLocationUpdates(
            LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);
}
