информировать пользователя, если интернет не подключен к дальнейшему процессу

Question

Я разрабатываю приложение, в котором я должен сообщить пользователю, что вы не подключены к Интернету для дальнейшего процесса. У меня есть две кнопки принять и отклонить, когда мы нажимаем на любой из кнопок он должен уведомить подключиться к Интернету

private void initializeClickListeners() { 
    acceptB.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 

      final int checkedOrders = checkedCheckboxArray.size(); 
      Log.v(TAG,"size of the checked orders is: "+checkedOrders); 

      String msgOrdersText = "Order"; 
      if(checkedOrders == 0) 
      { 
       Toast.makeText(getActivity(), "No Order Selected", Toast.LENGTH_SHORT).show(); 
      } 
      else if(checkedOrders != 0) 
      { 
       AlertDialog.Builder adb = new AlertDialog.Builder(getActivity()); 

       if(checkedOrders==1) 
       { 
        msgOrdersText = "Order"; 
       } 
       if(checkedOrders>1) 
       { 
        msgOrdersText = "Orders"; 
       } 
       adb.setTitle("Accept "+msgOrdersText); 
       adb.setMessage("Do you want to deliver "+checkedOrders+" "+msgOrdersText); 
       adb.setPositiveButton("Yes", 
       new DialogInterface.OnClickListener() { 
        @Override 
        public void onClick(DialogInterface dialog, int which) { 

         //Log.v(TAG,"Adding orders to current list on Acceptance"); 

         int oId; 
         DatabaseHelper db = new DatabaseHelper(getActivity()); 
         db.getReadableDatabase(); 
         Cursor cursor = db.getNewOrders(); 
         Log.v(TAG,"Count: "+cursor.getCount()); 
         StringBuilder orderIds = new StringBuilder();

          orderIds.append(oId+"$"); 
         } 


         Log.v(TAG,"Selected orders in string: "+orderIds); 
         UpdateSelectedOrdersStatusAsyncTask updateStatus = new UpdateSelectedOrdersStatusAsyncTask(); 
         updateStatus.execute(orderIds.toString(),"1"); 

         cursor.close(); 
         db.close(); 
         Toast.makeText(getActivity(), checkedOrders+" order accepted", Toast.LENGTH_SHORT).show(); 

         // set the selected orders to none 
         checkedCheckboxArray.clear(); 

         // set the state of checkbox for all the items in list to false 
         for(int i=0;i<checkedState.length;i++) 
         { 
          checkedState[i] = false; 
         } 


         // refill the list adapter 
         fillAdapter(0); 
         // update the order count notification in menu bar 
         setNotificationCounter(); 

        } 
       }); 
       adb.setNegativeButton("No", 
       new DialogInterface.OnClickListener() { 

        @Override 
        public void onClick(DialogInterface dialog, int which) { 
         Log.v(TAG,"Orders not added to the current list"); 
         //checkedCheckboxArray.clear(); 
        } 
       }); 
       AlertDialog ad = adb.create(); 
       ad.show(); 
      } 
     } 
    }); 


    rejectB.setOnClickListener(new View.OnClickListener() { 
     @Override

      { 
       AlertDialog.Builder adb = new AlertDialog.Builder(getActivity());

       adb.setNegativeButton("No", 
       new DialogInterface.OnClickListener() { 

        @Override 
        public void onClick(DialogInterface dialog, int which) { 
         Log.v(TAG,"Orders not added to the current list"); 
        } 

       }); 

       AlertDialog ad = adb.create(); 
       ad.show(); 
      } 
     } 
    }); 

Теперь я кладу моего устройства код статуса интернет

public class DeviceInternetStatus { 

    private static final String TAG = "Buzz"; 
    private static DeviceInternetStatus instance = new DeviceInternetStatus(); 
    static Context context; 
    ConnectivityManager connectivityManager; 
    NetworkInfo wifiInfo, mobileInfo; 
    boolean connected = false; 


    public static DeviceInternetStatus getInstance(Context ctx) { 
     context = ctx.getApplicationContext(); 
     return instance; 
    } 

    public boolean isOnline() { 

     try { 
      connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE); 
      NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo(); 
      Log.v(TAG,"Type of Network(Device Internet Status): "+networkInfo); 
      connected = networkInfo != null && networkInfo.isAvailable() && networkInfo.isConnected(); 
      return connected; 
     } catch (Exception e) { 
      Log.v("Buzz","Connectivity Exception"+ e.toString()); 
     } 
     return connected; 
    } 

Answer 1

Вам нужно создать конструктор передавая объект OnItemClickListener

как это,

static Class<? extends OnItemClickListener> cls; 
public static DeviceInternetStatus getInstance(OnItemClickListner listner) { 
    cls=listener.getClass(); 
    return instance; 
}
