在android中如何获取值

Question

我的android应用程序中有这个JSON字符串

[{"tel1":"999","tel2":"0790000000","tel3":"","interval":"60","deleteLocal":"1","id":"2"}]

如何将其解析为JsonArray，然后获取值，例如，tel1？

Answer 1

try
    {
       JSONArray jArray= new JSONArray(output);
       JSONObject jsonObject=jsonArray.getJSONObject(0);
       String tel= jsonObject.getString("tel1");
    }catch(Exception e)
    {
     //error parsing response.
    }

Answer 2

就像这样

{-表示JsonObject

[- -代表JsonArray

  try
        {
        JSONArray jArray= new JSONArray(output);
               JSONObject menuObject = JSONArray.getJSONObject(0);  
               String tel= menuObject.getString("tel1");
        }catch(Exception e)
        {

Log.e("d",e.getMessage());
        }

Answer 3

试试这个

try {
        JSONArray jsonArray = new JSONArray(responsestring);
        for (int i = 0; i < jsonArray.length(); i++) {

            JSONObject jobj = jsonArray.getJSONObject(i);
            String strtel1 = jobj.getString("tel1");

            Log.i("value tel1 : ", strtel1 + "");
        }
    } catch (JSONException e) {
        // TODO: handle exception
    }
