Ошибка: конструктор Geocoder (Context, Locale) не определен

Я хочу получить город, но я пробую со следующим кодом и покажу мне: «Конструктор Geocoder (SitesAdapter, Locale) не определен», я пробую много способов в этот форум и другие, и я не нашел правильного решения. Каким будет правильный контекст в Geocoder (Context, Locale) ?.Ошибка: конструктор Geocoder (Context, Locale) не определен

Geocoder:

Geocoder geocoder; 
List<Address> addresses; 
geocoder = new Geocoder(SitesAdapter.this, Locale.getDefault()); 
addresses = geocoder.getFromLocation(lat, lng, 1);  
String city= addresses.get(0).getAddressLine(1);

Полный код:

public class SitesAdapter extends ArrayAdapter<StackSite> { 

    public SitesAdapter(Context ctx, int textViewResourceId, List<StackSite> sites) { 
     super(ctx, textViewResourceId, sites); 
    } 

    @Override 
    public View getView(int pos, View convertView, ViewGroup parent){ 
     ...   
     //Get our View References 
     TextView tituloTxt = (TextView)row.findViewById(R.id.tituloTxt); 
     TextView fechaTxt = (TextView)row.findViewById(R.id.fechaTxt); 
     TextView magTxt = (TextView)row.findViewById(R.id.magTxt); 
     TextView depthTxt = (TextView)row.findViewById(R.id.depthTxt); 

     String stringlat = this.getItem(pos).getLat(); 
     Double lat = Double.parseDouble(stringlat); 
     String stringlng = this.getItem(pos).getLng(); 
     Double lng = Double.parseDouble(stringlng); 

     String dateUTC = this.getItem(pos).getFecha(); 
     String stringDepth = this.getItem(pos).getDepth(); 
     Double depth = Double.parseDouble(stringDepth);    

     //GET CITY 
     Geocoder geocoder; 
     List<Address> addresses; 
     geocoder = new Geocoder(SitesAdapter.this, Locale.getDefault()); 
     addresses = geocoder.getFromLocation(lat, lng, 1);  
     String city= addresses.get(0).getAddressLine(1);  
     ...         
    }  
}

UPDATE Окончательный код - первое решение:

Geocoder geocoder; 
List<Address> addresses = null; 
    geocoder = new Geocoder(mContext, Locale.getDefault()); 
    try { 
     addresses = geocoder.getFromLocation(lat, lng, 1); 
    } catch (IOException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    }  
    String city= addresses.get(0).getAddressLine(1);

LogCat - первое решение:

я могу решить проблему с этим кодом:

String city = null; 
Geocoder gc = new Geocoder(mContext, Locale.getDefault());  
List<Address> list; 
try { 
    list = gc.getFromLocation(lat, lng,1); 
    if (list != null && list.size() > 0) { 
     Address address = list.get(0); 
     city = address.getAdminArea(); 
    } 
} catch (IOException e) { 
    // TODO Auto-generated catch block 
    e.printStackTrace(); 
}

Вы можете проверить это sample. Удачи

Вы должны использовать Context в качестве первого параметра (может быть Activity). У вас есть один переданный конструктор вашего адаптера. Просто добавьте его в локальную переменную и используйте ее для геокодирования.

public class SitesAdapter extends ArrayAdapter<StackSite> { 
    private Context mContext; 

    public SitesAdapter(Context ctx, int textViewResourceId, List<StackSite> sites) { 
     super(ctx, textViewResourceId, sites); 
     mContext = ctx; 
    } 

    @Override 
    public View getView(int pos, View convertView, ViewGroup parent){ 
     ... 
     //GET CITY 
     Geocoder geocoder; 
     List<Address> addresses; 
     geocoder = new Geocoder(mContext, Locale.getDefault()); 
     addresses = geocoder.getFromLocation(lat, lng, 1);  
     String city= addresses.get(0).getAddressLine(1);   

     ...  
    } 
}

Спасибо @Pycpik это работает, но теперь появляется ошибка в этой строке address = geocoder.getFromLocation (lat, lng, 1); и покажите мне 1 исправление «Surround with try/catch», а затем я инициализировал адреса переменных с «нулевым» значением, но при запуске приложения покажите мне ошибку и закройте. Я поставил лог-кот в вопрос. Спасибо за помощь. –

Возможны разные вопросы. Возможно, устройство не реализует геокодер (он не является частью AOSP): проверьте [здесь] (http://stackoverflow.com/questions/4761052/why-is-android-geocoder-throwing-a-service-not- доступное исключение) ИЛИ проблема с сервисом networkLocator: проверьте [здесь] (http://stackoverflow.com/questions/15110528/service-not-available-while-calling-geocoder-getfromlocation). Попробуйте перезагрузить тоже! – Pycpik
