NullPointerException on listview.getCount() method -

-

application crashes throwing null pointer exception on line roomlist.getadapter().getcount(). need fetch each edit text value listview , apply computations on it, after searching various posts, have found out solution not working properly.

roomlist = (listview) vi.findviewbyid(r.id.list2); (int = 0; < roomlist.getadapter().getcount(); i++) {         view view = roomlist.getchildat(i);         edittext edit = (edittext) view.findviewbyid(r.id.editroom);         log.d("value each edit text", edit.gettext().tostring()); }

you have npe because roomlist.getadapter() returns null. maybe didn't call roomlist.setadapter(listadapter adapter).

by way, should change name roomlist roomlist, stick java convention. roomlist.getadapter() @ first glance looks static method call of roomlist class.

when save object, got below error must non-abstract type public parameterless constructor in order use parameter 't' in generic type or method 'servicestack.redis.redisclient.store<t>(t) redisclass.getinstnace().store(msg); // error here redisclass.getinstnace().save(); as third party's class, can not edit how save object? could create wrapper around third party object call constructor, store wrapper? e.g. public class mywrapper { public thirdpartyobject thirdpartyinstance { get; set; } public mywrapper() { thirdpartyinstance = new thirdpartyobject("constructors"); } }

time series - R growth rate calculation week over week on daily timeseries data -

-
i'm trying calculate w/w growth rates entirely in r. use excel, or preprocess ruby, that's not point. data.frame example date gpv type 1 2013-04-01 12900 office 2 2013-04-02 16232 office 3 2013-04-03 10035 office i want factored 'type' , need wrap date type column weeks. , calculate week on week growth. i think need ddply group week - custom function determines if date in given week or not? then, after that, use diff , find growth b/w weeks divided previous week. then i'll plot week/week growths, or use data.frame export it. this closed had same useful ideas. update: answer ggplot: all same below, use instead of plot ggplot(data.frame(week=seq(length(gr)), gr), aes(x=week,y=gr*100)) + geom_point() + geom_smooth(method='loess') + coord_cartesian(xlim = c(.95, 10.05)) + scale_x_discrete() + ggtitle('week on week growth rate, apr 1') + ylab('growth rate %') (old, correct answer using plot) w...
