如何将排球响应存储到HashMap中？

Question

  

我已经创建了HashMap和JsonArrayRequest对象，如下所示。响应已成功检索但HashMap对象url_maps大小为零。我想在url_maps中使用for循环。

    HashMap<String,String> url_maps = new HashMap<String, String>();

    // Creating volley request obj for Banner
    JsonArrayRequest bannerReq = new JsonArrayRequest(bannerUrl,
            new Response.Listener<JSONArray>() {
                @Override
                public void onResponse(JSONArray response) {
                    Log.d(msg, response.toString());
                    // Parsing json
                    for (int i = 0; i < response.length(); i++) {
                        try {
                            JSONObject obj = response.getJSONObject(i);
                            url_maps.put("static key", "static value );
                        } catch (JSONException e) {
                            e.printStackTrace();
                        }

                    }

                    // notifying list adapter about data changes
                    // so that it renders the list view with updated data
                    //adapter.notifyDataSetChanged();
                }
            }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            VolleyLog.d(msg, "Error: " + error.getMessage());
        }
    });
    // Adding request to request queue
    AppController.getInstance().addToRequestQueue(bannerReq);

Answer 2

也许你可以改变：

url_maps.put("static key", "static value );

为：

url_maps.put(obj.getString("static key"),obj.getString("static value"));
