引起原因：java.lang.NumberFormatException：无效的双精度：“”带有空白值

当我遇到错误时JSON字符串有一些空白值，从服务器获取， 如何处理空白值 这是 JSON

{  
   "status":"success",
   "data":[  
      {  
         "id":"1",
         "name":"ABC",
         "address":"ABC, QWE",
         "lat":"16.799999",
         "lng":"96.150002",
         "admin_id":"4",
         "is_approved":"1",
         "added":"2015-08-07 11:17:12",
         "status":"1",
         "image_file":"",
         "image_width":"",
         "image_height":""
      }
   ]
}

Gson gson = new GsonBuilder().serializeNulls().create();
Type listType = new TypeToken<List<MyData>>() {}.getType();
myDataArrayList = gson.fromJson(response.getString("data"), listType);

在 MyData 类中我尝试更改lat, long type int并更改了 json 中的值也相同，但仍然显示相同的错误

public class MyData implements Parcelable {

    public int id;

    public String name;

    public String address;

    public String lat;

    public String lng;

    public String added;

    public int status;

    public String image_file;

    public int image_width;

    public int image_height;

}

显示这一行有错误

myDataArrayList = gson.fromJson(response.getString("data"), listType);

将MyData类中image_width和image_height的类型更改为String

public String image_width;

public String image_height;

由于int无法存储“”这个字符串，使用时可以将其解析为int。
