I have one page timeline like Facebook (there are EditText and Button), it has 2 async task. The first one is used to send parameter to remote server, the second one to load data json from URL. Actually first time, program will load JSON on the listview with async, then if I wanna update status after click Button then it will insert to table on the remote server. Both of them work successfully. But I have a little problem : after click button (update status) I want to refresh my listview. I have added the code on event click button, and then added onPostExecute (Class TheTask). After I send parameter, listview does not reload contents again. Can somebody help me to solve this problem ?
my source code :
