Question

I need to parse and display url content in listview. I have parsed title,date, content,name and image using lazyloading but now i need to parse url and display its content in listview.
But the problem here instead of diplaying url it is displaying image url. It is displaying like this http://imageshack.us/photo/my-images/18/device20130202121840.png/ following is my json response(only few response included here) and parsing code

Answer 1

you are getting issue because both key is same for KEY_SITEURL and KEY_URL in HashMap so just change any one key to get it work as :

static final String KEY_URL_FOR_MAP = "url_site";   //use this for adding 
                                               //and retrivng value from Hashmap
static final String KEY_URL = "url";   // use this for getting url JsonObject
static final String KEY_SITEURL = "url";

now use KEY_URL_FOR_MAP for adding url to Hashmap and to retrieve url form HashMap
