android - How do I add a rotating spinner to my webview? -


i have made webview in require add loading /rotating spinner. have image same, not sure how go such when webview loads starts rotating , when entire view loaded stops. here code far:

 @override     public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) {          view view = inflater.inflate(r.layout.fragment_search_answers, container, false);       mwebview =  (webview)view.findviewbyid(r.id.webview);           mwebview.setvisibility(view.visible);               mwebview.setwebviewclient(new mywebviewclient(this, mwebview));             mwebview.getsettings().setpluginstate(pluginstate.on);             mwebview.getsettings().setusewideviewport(true);             mwebview.getsettings().setdefaultzoom(zoomdensity.far);             mwebview.getsettings().setbuiltinzoomcontrols(true);             mwebview.getsettings().setsupportzoom(true);             mwebview.getsettings().setjavascriptcanopenwindowsautomatically(true);             mwebview.getsettings().setallowfileaccess(true);             mwebview.getsettings().setdomstorageenabled(true);             mwebview.getsettings().setjavascriptenabled(true);             mwebview.sethttpauthusernamepassword(host, realm, username, password);             mwebview.getsettings().setappcacheenabled(true);             if (build.version.sdk_int >= build.version_codes.honeycomb)                 mwebview.getsettings().setdisplayzoomcontrols(false);              mwebview.loadurl(url);           return view;     }

p.s:i add constant animated rotation. here code rotate.xml added under animations:

<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android">     <rotate         android:fromdegrees="180.0"         android:todegrees="0.0"         android:pivotx="50%"         android:pivoty="50%"         android:duration="200"     /> </set>

any idea how can connect webview imae , rotate.xml meets expected criteria?

thanks! justin

the solution easy: below line:

view view = inflater.inflate(r.layout.fragment_search_answers, container, false);       mwebview =  (webview)view.findviewbyid(r.id.webview);

add:

mpbar = (progressbar) view.findviewbyid(r.id.web_view_progress);

after setting in title as: 

private progressbar mpbar = null;

and go web view client section , add :

@override         public void onpagestarted(webview view, string url, bitmap favicon) { mpbar.setvisibility(view.visible); }

and :

public void onpagefinished(webview view, string url) { mpbar.setvisibility(view.gone);         }

ad not forget set <progressbar style , required width height below <webview> in xml , wonders.
