android - Check generated ListView time -

i know how can track time spent draw/populate list view. using custom array adapter using list. thinking of using system.nanotime().

i tried following code:

    @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) {     long startnano = system.nanotime();     view view = inflater.inflate(r.layout.trip_listview, container, false);     listview lv = (listview) view.findviewbyid(android.r.id.list);     tripsarrayadapter tripsarrayadapter = new tripsarrayadapter(getactivity(), cacheddata.getinstance().gettripslist());     lv.setadapter(tripsarrayadapter);     long endnano= system.nanotime();     system.out.println("time create: "+(endnano-startnano));     return view; } 

is correct way?

i wouldn't rely on above code drawing not done within setadapter method. use hierarchyviewer , check how each view took draw , layout.

there great article on developer website on debugging ui , there another article romain guy treats ui performance.
