timer - Android ViewFlipper showPrevious after 300ms -

-

hey. started android. i'm using viewflipper layout 2 linearlayouts. first layout has button switches second layout. add timer switch first layout after 3000ms. tried thread did not work (can not communicate ui element of other thread).

my code:

public class test extends activity {

viewflipper f; linearlayout l1; linearlayout l2; button b1;  thread s;  @override public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.main);      f = (viewflipper) findviewbyid(r.id.f);     l1 = (linearlayout) findviewbyid(r.id.l1);     l2 = (linearlayout) findviewbyid(r.id.l2);     b1 = (button) findviewbyid(r.id.b1);      updateswitch = new thread() {         @override         public void run() {             try {sleep(3000);             } catch (interruptedexception e) {             } {f.showprevious();}         }     };      b1.setonclicklistener(new view.onclicklistener() {          @override         public void onclick(view v) {             f.setanimation(animationutils.loadanimation(v.getcontext(), r.anim.push_left_in));             lflipper.shownext();             updateswitch.start();         }     }); }

}

my guess need kind of handler connect new thread main thread. please update code. thx 10x.

you need read technical article updating ui timer
