multithreading - Dialog wait for download and thread issuse -


i'm trying display dialog when user attempts download something, when dialog dismissed, app redirects earlier form page. download works next form not; keeps displaying 'loading' dialog , returning previous form.

the looping form commented out of code below..

    connectionrequest request = new connectionrequest();  //        infiniteprogress ip = new infiniteprogress(); //        dialog dlg = ip.showinifiniteblocking(); //        request.setdisposeoncompletion(dlg);           hashtable param_data_url = new hashtable();           param_data_url.put("index", 0);           param_data_url.put("rango", 10);           param_data_url.put("ciudad_id", constants.codigociudadactual);            string urlbusqueda = constants.url_servicio_show_productos_adom_movil;           string url_conexion = constants.geturlservicio(constants.url_servidor_aplicacion, constants.url_aplicacion, urlbusqueda, param_data_url);            request.seturl(url_conexion);                      request.addresponselistener(new actionlistener() {                         public void actionperformed(actionevent evt) { networkevent netevt = (networkevent) evt;

}

your indentation , block of code makes impossible read , cut off top of call impossible know. however, since return sort of method , return value i'm assuming logic incorrectly expects synchronous behavior addtoqueue asynchronous.

try changing addtoqueue addtoqueueandwait.
