大家好,我正在读一个包含Java(Android)的JSON对象的页面
以下是页面内容:

{
   "destination_addresses" : [ "Safi, Maroc" ],
   "origin_addresses" : [ "Avenue Hassan II, Safi, Maroc" ],
   "rows" : [
      {
         "elements" : [
            {
               "distance" : {
                  "text" : "1,0 km",
                  "value" : 966
               },
               "duration" : {
                  "text" : "2 minutes",
                  "value" : 129
               },
               "status" : "OK"
            }
         ]
      }
   ],
   "status" : "OK"
}

我知道怎么从这一页读
    JSONObject jArray = new JSONObject(result);
    String elements = jArray.getString("rows");

元素字符串包含:
[{"elements" : [{"distance" : {"text" : "1,0 km","value" : 966},"duration" : {"text" : "2 minutes","value" : 129},"status" : "OK"}]}]

但是我试图得到距离值,它是“966”
谢谢大家

最佳答案

试试这个…

JSONObject jObj = new JSONObject(result);
JSONArray rows = jObj.getJSONArray("rows");
for(int i = 0; i < rows.length; i++){
     JSONObject obj = rows.getJSONObject(i);
     JSONArray elements = jObj.getJSONArray("elements");
     for(int j = 0; j < elements.length; j++){
          JSONObject Jobj = elements.getJSONObject(j);
          JSONObject distance = Jobj.getJSONObject("distance");
          int distance_value = distance.getInteger("value");
          JSONObject duration = Jobj.getJSONObject("duration");
          int duration_value = duration.getInteger("value");
     }
}
