我正在尝试解析 JSON 响应,我可以在其中解析标题、日期、内容和名称,但我无法解析 url 并将其显示在 Listview 中。当我解析 url 它在 textview 中显示图像 url 任何人都可以指导我正确的路径

 try {
                     posts = json.getJSONArray(KEY_POSTS);

        // looping through all song nodes <song>
                for(int i = 0; i < posts.length(); i++){
                    JSONObject c = posts.getJSONObject(i);

                    // Storing each json item in variable
                    String id = c.getString(KEY_ID);
                    String siteurl = c.getString(KEY_SITEURL);
                    String title = c.getString(KEY_TITLE);
                    String date = c.getString(KEY_DATE);
                    String content = c.getString(KEY_CONTENT);
                    // to remove all <P> </p> and <br /> and replace with ""
                     content = content.replace("<br />", "");
                     content = content.replace("<p>", "");
                     content = content.replace("</p>", "");

                    //authornumber is agin  JSON Object
                    JSONObject author = c.getJSONObject(KEY_AUTHOR);
                    String name = author.getString(KEY_NAME);

                    String url1 = null;
                    String slug1 = null;
                    try {
                    JSONArray atta = c.getJSONArray("attachments");
                    for(int j = 0; j < atta.length(); j++){
                        JSONObject d = atta.getJSONObject(j);

                        slug1 = d.getString(KEY_SLUG);

                        JSONObject images = d.getJSONObject(KEY_IMAGES);

                        JSONObject thumbnail = images.getJSONObject(KEY_THUMB_URL);
                        url1 = thumbnail.getString(KEY_URL);

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

                    }




            // creating new HashMap
            HashMap<String, String> map = new HashMap<String, String>();

            // adding each child node to HashMap key => value
            map.put(KEY_ID, id);
            map.put(KEY_TITLE, title);
            map.put(KEY_SITEURL, siteurl);
            map.put(KEY_DATE, date);
            map.put(KEY_NAME, name);
            map.put(KEY_CONTENT, content);
            map.put(KEY_SLUG, slug1);
            map.put(KEY_URL, url1);


            // adding HashList to ArrayList
            songsList.add(map);
                }   
                }catch (JSONException e) {
                    e.printStackTrace();

                    }
