GPS定位xamarin的Android不工作

Question

• 在列表Viewlist产品项目获得GPS位置，但它不工作（public class ItemGeoLocationActivity : ListActivity, ILocationListener the class）

请看看吧我做错了什么。

[Activity(Label = "ItemGeoLocationActivity")] 
public class ItemGeoLocationActivity : ListActivity, ILocationListener 
{ 
LocationManager _locMgr; 
     private string Latitude; 
     private string Longitude; 
     protected override void OnCreate(Bundle bundle) 
     { 
      base.OnCreate(bundle); 
      _locMgr = GetSystemService(Context.LocationService) as LocationManager; 
      list = new ItemGeoLocationAdapter(this); 
      this.ListAdapter = list; 
     } 

     protected override void OnListItemClick(ListView l, View v, int position, long id) 
     { 
      var item = this.list.GetItemAtPosition(position); 

      var builder = new AlertDialog.Builder(this); 
      builder.SetMessage(item.ItemName + "-- Latitude ="+Latitude+" Longitude="+Longitude); 
      builder.SetPositiveButton("OK", (s, e) => 
      { 
       var itemGeoLocation =new ItemGeoLocation 
       { 
        ItemId = item.ItemId, 
        Langtitued = Convert.ToDecimal(Longitude), 
        Latitued = Convert.ToDecimal(Latitude) 
       }; 
       new DataAccess().AddItemGeoLocation(itemGeoLocation); 
       Toast.MakeText(this, item.ItemName + "-- Recode Added Succesafully", ToastLength.Long).Show(); 

      }); 
      builder.SetNegativeButton("Cancel", (s, e) => 
      { 
       Toast.MakeText(this, item.ItemName + " Save Cancelation Success!", ToastLength.Long).Show(); 

      }); 
      builder.Create().Show(); 

     } 

     protected override void OnResume() 
     { 
      base.OnResume(); 
      var locationCriteria = new Criteria(); 
      locationCriteria.Accuracy = Accuracy.NoRequirement; 
      locationCriteria.PowerRequirement = Power.NoRequirement; 
      string locationProvider = _locMgr.GetBestProvider(locationCriteria, true); 
      _locMgr.RequestLocationUpdates(locationProvider, 2000, 1, this); 
     } 

     protected override void OnPause() 
     { 
      base.OnPause(); 
      _locMgr.RemoveUpdates(this); 
     } 

     #region ILocationListener implementation 
     public void OnLocationChanged(Location location) 
     { 
      Latitude = location.Latitude.ToString(); 
      Longitude=location.Longitude.ToString(); 
     } 

     public void OnProviderDisabled(string provider) 
     { 
     } 

     public void OnProviderEnabled(string provider) 
     { 
     } 

     public void OnStatusChanged(string provider, Availability status, Bundle extras) 
     { 
     } 

}
