问题描述

我正在开发一个小型 android 应用程序,我想在其中使用网络提供商找出用户的当前位置.我通过以下方式尝试了这个,但它没有给我任何输出:

I am developing a small android application in which I want to find out the user's current location by using the network provider. I tried this in following ways but it's not giving me any output :

networklocationManager = (LocationManager) this
        .getSystemService(Context.LOCATION_SERVICE);
// Define a listener that responds to location updates
LocationListener networklocationListener = new LocationListener() {

    public void onLocationChanged(Location location) {
        Log.i("********************************",
                "this is my network location " + location);
        String Location_text = "NETWORK LOCATION latitude:"
                + location.getLatitude() + " longitude:"
                + location.getLatitude();
        network_location.setText(Location_text);
    }

    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
networklocationManager
        .requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0,
                networklocationListener);

我像这样在清单文件中授予权限

I gave permissions in my manifest file like this

 <uses-permission 
    android:name="android.permission.INTERNET" />
<uses-permission
    android:name="android.permission.ACCESS_COARSE_LOCATION" />
 <uses-permission
    android:name="android.permission.ACCESS_FINE_LOCATION" /> 

有什么我想念的吗?这是正确的方法吗?需要帮忙.谢谢...

Is there any thing which I am missing ? Is this the correct way? Need help. Thank you...

public class MainActivity extends Activity implements LocationListener {

    private TextView latituteField;
    private TextView longitudeField;
    private LocationManager gpslocationManager;
    private LocationManager networklocationManager;
    private LocationManager networklocationManager1;
    private String provider;
    private TextView gps_location;
    private TextView network_location;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        gps_location = (TextView) findViewById(R.id.gps_location);
        network_location = (TextView) findViewById(R.id.network_location);
        networkLocation();
    }

    public void networkLocation() {
        networklocationManager = (LocationManager) this
                .getSystemService(Context.LOCATION_SERVICE);
        LocationListener networklocationListener = new LocationListener() {

            public void onLocationChanged(Location location) {
                Log.i("********************************",
                        "this is my network location " + location);
                String Location_text = "NETWORK LOCATION latitude:"
                        + location.getLatitude() + " longitude:"
                        + location.getLatitude();
                network_location.setText(Location_text);
            }

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

            public void onProviderEnabled(String provider) {}

            public void onProviderDisabled(String provider) {}
        };
        networklocationManager
                .requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0,
                        networklocationListener);
    }
}

推荐答案

你的网络供应商启用了吗?

Is your network provider enabled?

boolean network_enabled;
try {
    network_enabled = locManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
} catch(Exception ex) {
   ex.printStackTrace();
}
