Google Places：Android API：Place class缺少一些數據

Question

我發現Google Maps API的Android Library的Place類遺漏了很多Web服務API中可用的數據。

的Android類： https://developers.google.com/android/reference/com/google/android/gms/location/places/Place

網絡服務回覆： https://developers.google.com/places/web-service/details?hl=en

例如，類定義必須一無所知評論或營業時間。爲什麼是這樣？是否有可能解決它而無需將所有應用程序轉換爲Web服務API調用和json解析？也許有能力將Place對象轉換爲原始的JSON形式來查找一些額外的數據？在Android的

Answer 1

Places API的唯一的，如果你想你要調用Web服務API的更多詳細信息返回類似地名，經緯度等幾個細節。這是URL

https://maps.googleapis.com/maps/api/place/details/json?key={API_KEY}&placeid={PLACE_ID} 

這裏PLACE_ID將得到放置對象在Android的Places API的

輸出示例：

樣品JSON解析Android中

String postalCode=""; 
        String city=""; 
        String state=""; 
        String address=""; 

        JSONObject jsonObj=new JSONObject(rs); 
        JSONArray addressComponents = jsonObj.getJSONObject("result").getJSONArray("address_components"); 
        for(int i = 0; i < addressComponents.length(); i++) { 
         JSONArray typesArray = addressComponents.getJSONObject(i).getJSONArray("types"); 
         for (int j = 0; j < typesArray.length(); j++) { 
          if (typesArray.get(j).toString().equalsIgnoreCase("postal_code")) { 
           postalCode = addressComponents.getJSONObject(i).getString("long_name"); 
          }else if (typesArray.get(j).toString().equalsIgnoreCase("locality")) { 
           city = addressComponents.getJSONObject(i).getString("long_name"); 
          }else if (typesArray.get(j).toString().equalsIgnoreCase("administrative_area_level_1")) { 
           state = addressComponents.getJSONObject(i).getString("long_name"); 
          }else { 
           String types=typesArray.get(j).toString(); 
           if(types.equalsIgnoreCase("street_number") 
             ||types.equalsIgnoreCase("route") 
             ||types.equalsIgnoreCase("neighborhood") 
             ||types.equalsIgnoreCase("sublocality_level_1") 

             ) 
           address+=addressComponents.getJSONObject(i).getString("long_name")+", "; 
          } 
         } 
        }
