使用此方法代替线程

 zoomin.setAnimationListener(new AnimationListener() {

        @Override
        public void onAnimationStart(Animation arg0) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onAnimationRepeat(Animation arg0) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onAnimationEnd(Animation arg0) {
            bgImage.startAnimation(zoomout); 

        }
    });

和

 zoomout.setAnimationListener(new AnimationListener() {

        @Override
        public void onAnimationStart(Animation arg0) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onAnimationRepeat(Animation arg0) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onAnimationEnd(Animation arg0) {
            bgImage.startAnimation(zoomin); 

        }
    });
