try code, may works you
jsonobject table = jparser.getjsonfromurl(url); jsonarray json = table.getjsonarray("table2"); (int = 0; < json.length(); i++) { seek { jsonobject c = json.getjsonobject(i); string number = c.getstring(phonenumber); string info = c.getstring(peoplenumber); string remarkss = c.getstring(remarks); string statuss = c.getstring(status); hashmap<string, string> map = new hashmap<string, string>(); // add together kid node hashmap key & value map.put(phonenumber, number); map.put(peoplenumber, info); map.put(remarks, remarkss); map.put(status, statuss); jsonlist.add(map); } grab (jsonexception e) { e.printstacktrace(); } } i think have jasonarray in jsonobject
android json listview
