未能在Weatherlib API中檢索搜索到的城市android

Question

我正嘗試使用Weatherlib API創建天氣應用程序。我有下面的代碼。我試圖尋找城市模式，但不幸的是，okhttp引發了url == null的異常。

我創建了驗證，當至少輸入4個字母時開始搜索。一旦我輸入第四個字母，我得到這個例外...

有沒有人使用Weatherlib並遇到此問題？下面

ForecastIOProvider

WeatherClient.ClientBuilder builder = new WeatherClient.ClientBuilder(); 
    WeatherConfig config = new WeatherConfig(); 
    config.unitSystem = WeatherConfig.UNIT_SYSTEM.I; 
    config.lang = "en"; // set language to english 
    config.maxResult = 5; // max number of cities retrieved 
    config.numDays = 6 ; //maximum days in the forecast 


    try { 
     client = builder.attach(this) 
       .provider(new ForecastIOProviderType()) 
       .httpClient(WeatherDefaultClient.class) 
       .config(config) 
       .build(); 
    } catch (WeatherProviderInstantiationException e) { 
     e.printStackTrace(); 
    } 

    final EditText searchedText = (EditText) findViewById(R.id.searchText); 

    searchedText.addTextChangedListener(new TextWatcher() { 
     @Override 
     public void beforeTextChanged(CharSequence s, int start, int count, int after) { 
     } 

     @Override 
     public void onTextChanged(CharSequence s, int start, int before, int count) { 
      search = searchedText.getText().toString(); 
      if (search.length() > 3) 
      { 
       list.clear(); 
       try { 
        System.out.println("testingbefore"); 
        // reaches this point for the last 
        client.searchCity(search.toString(), new WeatherClient.CityEventListener() { 

         @Override 
         public void onCityListRetrieved(List cities) { 
          // The data is ready 
          // does not reach this point 
          System.out.println("testing"); 
          for (Object c : cities) { 
           list.add(((City) c).getName()); 
          } 
         } 

         @Override 
         public void onWeatherError(WeatherLibException e) { 
          // Error on geting data 
          System.out.println("testingError"); 
         } 

         @Override 
         public void onConnectionError(Throwable throwable) {// Connection error 
          System.out.println("testingConnection"); 
         } 
        }); 
       } catch (Exception e) { 
        e.printStackTrace(); 
       } 

      } 

     } 

     @Override 
     public void afterTextChanged(Editable s) { 

     } 
    });

錯誤消息不支持通過城市名稱查詢，這樣的網址，你應該使用lat和長。 希望它可以幫助你！
