android - My activity doesnt recognise text equality -

can me, i'm killing myself on here. in activity have code , application displays currentq not equal (currentq.getodg() != answer.gettext()) answer can see through logcat log.d words identical. can't understand doing wrong.

08-25 05:28:45.125: d/yourans(25316): na život u mraku na život u mraku log cat

radiogroup grp = (radiogroup) findviewbyid(r.id.radiogroup1);     answer = (radiobutton) findviewbyid(grp.getcheckedradiobuttonid());     log.d("yourans", currentq.getodg() + " " + answer.gettext());     if (currentq.getodg().equals(answer.gettext())) {         answer.setbackgroundresource(r.drawable.radiotocan);         toast poruka1 = toast.maketext(getapplicationcontext(), "točno!",                 toast.length_long);         view vieew1 = poruka1.getview();         // vieew.setbackgroundcolor(color.parsecolor("#bd8bdc"));         vieew1.setbackgroundresource(r.drawable.toast1);         poruka1.setview(vieew1);         poruka1.setgravity(gravity.center_horizontal, 1, 1);         poruka1.show();          score1++;         log.d("score1", "your score" + score1);          new handler().postdelayed(new runnable() {              @override             public void run() {                  answer.setbackgroundresource(r.drawable.radiomain);             }         }, 300);     }      else if (currentq.getodg() != answer.gettext()) {          answer.setbackgroundresource(r.drawable.radionetocan);         toast poruka2 = toast.maketext(getapplicationcontext(),                 "netočno, točan odgovor je:" + currentq.getodg(),                 toast.length_long);         view vieew2 = poruka2.getview();         // vieew.setbackgroundcolor(color.parsecolor("#bd8bdc"));         vieew2.setbackgroundresource(r.drawable.toast);         poruka2.setview(vieew2);         poruka2.setgravity(gravity.center_horizontal, 1, 1);         poruka2.show();         new handler().postdelayed(new runnable() {              @override             public void run() {                  answer.setbackgroundresource(r.drawable.radiomain);             }         }, 300);     } 

try

if(currentq.getodg().equalsignorecase(answer.gettext())) 

instead of

if(currentq.getodg()!=answer.gettext()) 

hope helps!
