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");
}
}
