java - Arraylist not working with android -

i got problem , can't find anywhere. i'am making quiz app. , got mainactivity here:

public class mainactivity extends activity {      list<vragen> queslist;     int score=0;     int qid=0;     vragen currentq;     textview txtvragen;     radiobutton rda, rdb, rdc;     button butvolgende;     @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);         dbhelper db=new dbhelper(this);         queslist=db.getallvragen();         currentq=queslist.get(qid);         txtvragen=(textview)findviewbyid(r.id.txtvraag);         rda=(radiobutton)findviewbyid(r.id.antwoord1);         rdb=(radiobutton)findviewbyid(r.id.antwoord2);         rdc=(radiobutton)findviewbyid(r.id.antwoord3);         butvolgende=(button)findviewbyid(r.id.btnvolgende);         setvragenview();         butvolgende.setonclicklistener(new view.onclicklistener() {                  public void onclick(view v) {                 radiogroup grp=(radiogroup)findviewbyid(r.id.grpantwoord);                 radiobutton antwoord=(radiobutton)findviewbyid(grp.getcheckedradiobuttonid());                 log.d("yourans", currentq.getantwoord()+" "+antwoord.gettext());                 if(currentq.getantwoord().equals(antwoord.gettext()))                 {                     score++;                     log.d("score", "your score"+score);                 }                 if(qid<5){                                       currentq=queslist.get(qid);                     setvragenview();                 }else{                     intent intent = new intent(mainactivity.this, resultactivity.class);                     bundle b = new bundle();                     b.putint("score", score); //your score                     intent.putextras(b); //put score next intent                     startactivity(intent);                     finish();                 }             }         });     }     @override     public boolean oncreateoptionsmenu(menu menu) {         // inflate menu; adds items action bar if present.         getmenuinflater().inflate(r.menu.activity_main, menu);         return true;     }     private void setvragenview()     {         txtvragen.settext(currentq.getvraag());         rda.settext(currentq.getopt1());         rdb.settext(currentq.getopt2());         rdc.settext(currentq.getopt3());         qid++;     } } 

here dbhelper , questions in there:

can please me i'm stuck , need finished.

thanks in advance!

java.lang.indexoutofboundsexception: invalid index 1, size 1 

means tried second element in arraylist had 1 element. means when do

queslist=db.getallvragen(); 

you 1 result
