Hi Hi I'm trying to build a layout where some shapes will popup every 2 seconds. If the user will click one of these shapes, they have to disappear.

What is the correct way of doing this? I thought about a thread, but i missed out. Here's my code at the moment (is not working):

public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         l = new LinearLayout(this);
         setContentView(l);

     int counter = 1;
     View v = new CustomDrawableView(this,20,50);

     l.addView(v);

     Thread t = new Thread() {
          public void run() {


                  while (true) {
                        Log.i("THREAD","INSIDE");
                        View h = new CustomDrawableView(c,
                        (int)Math.round(Math.random()*100),

                        (int)Math.round(Math.random()*100));
                        SystemClock.sleep(2000);
                        l.addView(h);
                   }
              }
         };
         t.start();
    }
