java - Android Thread runOnUiThread -

i want make simple game, 1 image view , 2 buttons guess if card red of black.

i want use thread, every 0.1 seconds before player presses button, card changing.

this used far :

thread timer = new thread() {         public void run() {             while (true) {                 try {                     if(!isinterrupted())                         sleep(100);                     else                         sleep(5000);                     runonuithread(new runnable() {                         @override                         public void run() {                             if(!isinterrupted()) {                                 if (iv_card_to_guess.getdrawable() == null)                                     iv_card_to_guess.setimagebitmap(deck_card);                                 else                                     iv_card_to_guess.setimagedrawable(null);                             }                             else { //here need update imageview actual image of card, not deck or null // example 5 of hearts                                  loadbitmap(getresourceid("img_" + numbers.get(count).tostring(), "drawable", getapplicationcontext()), iv_card_to_guess);                             }                         }                     });                 } catch (interruptedexception e) {                     e.printstacktrace();                 }              }         }     }; 

when press button call timer.interrupt();

the application changes image of actual card 0.1 seconds, not 5 seconds, want :)

how can this, please?

     private timer timer;        timertask task = new timertask() {          @override         public void run() {             // todo auto-generated method stub           insert code want trigger here.         }     };     timer = new timer();      int delay=5000;      timer.schedule(task, delay);
