java - Button not updating its text -


i'm working android game. when application start show button ("start") start game. when user lose, application should show original view , changing button text "restart". when start application works fine when user lose original view (button text not changed) , button not responding. have 2 classes : gameactivity , gameview : in gameactivity have :

 protected void oncreate(bundle savedinstancestate) {       super.oncreate(savedinstancestate);     init();  }  public void init() {     setcontentview(r.layout.activity_catch_game);     fruitview = (catchgameview) findviewbyid(r.id.l3infocatchgameview1);     fruitview.setactivity(this);     if (bstart == null) { //when launch app         bstart = (button) findviewbyid(r.id.start);          bstart.setonclicklistener(new onclicklistener() {              @override             public void onclick(view v) {                 buttonstartclickeventhandler();              }          });     } else{         bstart.settext("restart");      }  }

in gameview have :

private void showscore() {     stoptimer();     alertdialog.builder popupbuilder = new alertdialog.builder(             this.getcontext());     textview message = new textview(this.getcontext());     message.settext("score : " + score);     message.setgravity(gravity.center_horizontal);     popupbuilder.setview(message);     popupbuilder.setcancelable(true);     popupbuilder.setneutralbutton("ok",             new dialoginterface.onclicklistener() {                 public void onclick(dialoginterface dialog, int id) {                     dialog.cancel();                     invalidate();                     activity.init();                 }             });     popupbuilder.show();  }

when debug see instruction change button text executed.

the problem init() method calls setcontentview().

when this, activity's layout re-inflated. of references views (such bstart) point views in old copy of layout, no longer visible user.

since bstart still referencing though, if (bstart == null) false , don't updated reference bstart.

i move separate logic updating button's text logic setting activity's layout.
