to add progress dialog while loading page on webview,add following code , no need add progressbar in xml.

//intialize progress dialog:   webview webview;   progressdialog progressdialog;  //write following code in oncreate:      webview=(webview)findviewbyid(r.id.webview);     progressdialog=new progressdialog(this);     progressdialog.setmessage("loading");     progressdialog.setprogressstyle(progressdialog.style_spinner);     progressdialog.show();

after loading webpage, have dismiss progressdialog.for in onpagefinish dismiss progressdialog.

webview.setwebviewclient(new webviewclient()     {         @override         public boolean shouldoverrideurlloading(webview view, string url) {             view.loadurl("your url");             return true;         }          @override         public void onpagefinished(webview view, string url) {             super.onpagefinished(view, url);             if (progressdialog.isshowing()) {                 progressdialog.dismiss();             }         }     });
