where id id of circle

but can't stop blink th.interupt

anyone can me please ?

thank @jibysthomas fixe problem use this link , made :

final animation animation = new alphaanimation(1, 0);          animation.setduration(250); // duration - half second         animation.setinterpolator(new linearinterpolator());          animation.setrepeatcount(animation.infinite);          animation.setrepeatmode(animation.reverse); 

and call annimation on circle.

thanks lot jibysthomas
