android - How to bind Radio Buttons using RxJava -

i'm following code of qiitanium app (see highlighted lines in link) , have trouble figuring out how can bind radiobuttons

say have radiogroup r.id.rgmybuttons id , contains 3 radiobuttons "dead", "alive", "body missing" ids r.id.rbdead, r.id.rbalive, r.id.rbmissing

i set radiogroup field as

rx<radiogroup> radiogroup; 

i view set in onviewcreated as

rdgroup = rxview.findbyid(this, r.id.rgmybuttons); rdgroup.get().setoncheckedchangelistener(monpersonstateupdatelistener); 

in onbind, i'd bind radiogroup model data value returns maps directly correct radiobutton in group. i'm looking like

rdgroup.bind(person.state(), rxactions.someaction()), 

so bound radiogroup , automatically sets correct value.

the person_state() returns 2 dead, 3 alive , 4 missing , want check correct field in radiogroup. how can achieve in rxandroid?

i able solve on own. here's answer might come across same issue....

i wrote function in class as

protected rxaction<radiogroup, string> setradiobutton() {     return new rxaction<radiogroup, string>() {         @override         public void call(final radiogroup radiogroup, final string selection) {            radiobutton rb;            switch(selection)            {                case "2":                    rb = (radiobutton)findviewbyid(r.id.rbdead);                    rb.setchecked(true);                    break;                 case "3":                    rb = (radiobutton)findviewbyid(r.id.rbalive);                    rb.setchecked(true);                    break;                 case "4":                    rb = (radiobutton)findviewbyid(r.id.rbmissing);                    rb.setchecked(true);                    break;             }         }     }; } 

and inside onbind used

rdgroup.bind(person.state(), setradiobutton()),
