android - save the radiobutton and check -


i need one..

i'm facing difficult in checks radio button.

my concept how save radio button in arraylist , again how check selected value arraylist. if suppose imagine quiz app. have set of questions , answers in separate array. i'm displaying it.its fine. if came pervious question should check selected answer has stored in arraylist. likewise next question. how implement this? feel difficult in this.

when 1st question displays check , answer this..

btn_practicerg.setoncheckedchangelistener(new oncheckedchangelistener(){     @override     public void oncheckedchanged(radiogroup group, int checkedid) {                  radiobutton radiobutton = (radiobutton)group. findviewbyid(checkedid);     string temp = radiobutton.gettext().tostring();

when press next button next question like same , answer in string , while press previous have used same that.. should not instead should check choosen answer..

sorry bad english. lot in advance..

  radiogroup = (radiogroup) findviewbyid(r.id.rdbgp1);   radiogroup.setoncheckedchangelistener(new radiogroup.oncheckedchangelistener() {                 @override public void oncheckedchanged(radiogroup group, int checkedid)            { // todo auto-generated method stub for(int i=0;                   radiobutton btn = (radiobutton) radiogroup.getchildat(i);                     string text;                                     if (btn.ispressed() && btn.ischecked() && questno < 5)                   {                        log.e("corrans[questno]",corrans[questno]);                   if (corrans[questno].equals(btn.gettext()) && flag==true)                  {                  score++;                  flag=false;                  checked = true;                   }                  else if(checked==true)                  {                  score--;                  flag=true;                  checked = false;                  }                      }              } tvscore.settext("score: " + integer.tostring(score) + "/5"); log.e("score:", integer.tostring(score)); } });

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
