Hi all I am able to get the json data however i only manage to dump all of them into a textview. How can i put it in to a listview. like every row will consist of "ib_itemcode1":2131 "transtatuscode":123 "invtid":1231 "descr":123123 in the application.

may i know how to go about it. i am already abit lost once it come to array adapter. Sorry i am pretty new to this.

Start by using a simple ArrayAdapter as described in #3 in http://www.vogella.com/tutorials/AndroidListView/article.html
