Question

我正在使用volley并实现json解析。我正在进行json解析并在列表视图中显示数据。我做了所有的事情（getter setter，singleton class，adapter等）但是在解析的时候我遇到了困难，如何解析

{
"result": [{
    "id": "1",
    "name": "Prabhat",
    "email": "prabhat@gmail.com"
}, {
    "id": "2",
    "name": "Apurva",
    "email": "apu@gmail.com"
}, {
    "id": "3",
    "name": "sunny",
    "email": "sunny@mail.com"
}, {
    "id": "4",
    "name": "Creation InfoTech",
    "email": "creation@gmail.com"
}, {
    "id": "5",
    "name": "Sanjay Mishra",
    "email": "sanju19@gmail.com"
}]

}

我的java代码是

 JsonObjectRequest request = new JsonObjectRequest(url_Array, new JSONObject(), new Response.Listener<JSONObject>() {
        @Override
        public void onResponse(JSONObject response) {

            for (int i = 0; i < response.length(); i++) {
                try {
                    Log.d(TAG, "working");
                    JSONObject object = response.getJSONObject(i);
                    // Now this is my PersonInfo class in which i have define my getters and setters
                    PersonInfo info = new PersonInfo(object.getString("id"), object.getString("name"), object.getString("email"));
                    personInfos.add(info);

                } catch (JSONException e) {
                    e.printStackTrace();
                }

            }
            adapter.notifyDataSetChanged();

        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            Toast.makeText(getApplicationContext(), "Something not ok", Toast.LENGTH_SHORT).show();

        }

    });
    AppController.getInstance(getApplicationContext()).AddtoRequestQueue(request);

}

Answer 1

在走完列表之前，首先需要获得JSONArray：

JSONArray array = response.getJSONArray("result")

然后你走了数组：

for (int i = 0; i < array.length(); i++) {...}

Answer 2

尝试此代码将帮助您将数据读入两个字符串数组，然后您可以随意使用它们

JsonObjectRequest request = new JsonObjectRequest(url_Array, new JSONObject(), new Response.Listener<JSONObject>() {
        @Override
        public void onResponse(JSONObject response) {
        JSONArray jsonArray = jsnobject.getJSONArray("result");
        String[] name=new String[jsonArray.length()];
        String[] email=new String[jsonArray.length()];
            for (int i = 0; i < jsonArray.length(); i++) {
                try {
                    Log.d(TAG, "working");
                    JSONObject student=jsonArray.getJSONObject(i);
                    name[i]=student.getString("name");
                    email[i]=student.getString("email");
                } catch (JSONException e) {
                    e.printStackTrace();
                }
            }
            adapter.notifyDataSetChanged();
        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            Toast.makeText(getApplicationContext(), "Something not ok", Toast.LENGTH_SHORT).show();
        }
    });    AppController.getInstance(getApplicationContext()).AddtoRequestQueue(request);

}
