問題描述

我正在開發(fā)一個小型 android 應(yīng)用程序，我想在其中使用網(wǎng)絡(luò)提供商找出用戶的當前位置.我通過以下方式嘗試了這個，但它沒有給我任何輸出:

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);

我像這樣在清單文件中授予權(quán)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" /> 

有什么我想念的嗎?這是正確的方法嗎?需要幫忙.謝謝...

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);
    }
}

推薦答案

你的網(wǎng)絡(luò)供應(yīng)商啟用了嗎?

Is your network provider enabled?

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

這篇關(guān)于網(wǎng)絡(luò)位置提供商不提供位置 android的文章就介紹到這了，希望我們推薦的答案對大家有所幫助，也希望大家多多支持html5模板網(wǎng)！
