我正在开发中，我想找出用户的当前位置利用网络提供一个小的Android应用程序。我在以下几个方面尝试过这一点，但它没有给我任何的输出：
networklocationManager =（LocationManager）本
.getSystemService（Context.LOCATION_SERVICE）;
//定义一个监听器，响应位置更新
LocationListener的networklocationListener =新LocationListener的（）{
公共无效onLocationChanged（位置定位）{
Log.i（*********，
这是我的网络位置+位置）;
字符串Location_text =网络位置纬度：
+ location.getLatitude（）+经度：
+ location.getLatitude（）;
network_location.setText（Location_text）;
}
公共无效onStatusChanged（字符串商，INT地位，
捆绑演员）{}
公共无效onProviderEnabled（字符串提供商）{}
公共无效onProviderDisabled（字符串提供商）{}
};
//注册监听器的位置管理器接收位置
//更新
networklocationManager
.requestLocationUpdates（LocationManager.NETWORK_PROVIDER，0，0，
networklocationListener）;
我在清单文件中像这样给权限
＆LT;使用，许可
机器人：名称=android.permission.INTERNET对/＆GT;
＆LT;使用，许可
机器人：名称=android.permission.ACCESS_COARSE_LOCATION/＆GT;
＆LT;使用，许可
机器人：名称=android.permission.ACCESS_FINE_LOCATION/＆GT;
有哪些我缺少什么东西？这是正确的方法是什么？需要帮忙。谢谢你...

解决方案
已启用您的网络供应商？
布尔network_enabled;
尝试 {
network_enabled = locManager.isProviderEnabled（LocationManager.NETWORK_PROVIDER）;
}赶上（例外前）{
ex.printStackTrace（）;
}
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);
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" />
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);
}
}
解决方案
Is your network provider enabled?
boolean network_enabled;
try {
network_enabled = locManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
} catch(Exception ex) {
ex.printStackTrace();
}
