        list = (ListView) findViewById(R.id.list);
        list.setAdapter(new ArrayAdapter(this, android.R.layout.simple_list_item_1,
                str_name));
        Animation animation = AnimationUtils.loadAnimation(this, R.anim.anim_item);
        LayoutAnimationController controller = new LayoutAnimationController(animation);
