Animation mShowAction = new TranslateAnimation(Animation.RELATIVE_TO_SELF,
        0.0f, Animation.RELATIVE_TO_SELF, 0.0f,
        Animation.RELATIVE_TO_SELF, -0.175f, Animation.RELATIVE_TO_SELF,
        0.0f);
mShowAction.setFillAfter(true);
mShowAction.setDuration(2000);
move.startAnimation(mShowAction);

Animation mHiddenAction = new TranslateAnimation(Animation.RELATIVE_TO_SELF,
            0.0f, Animation.RELATIVE_TO_SELF, 0.0f,
            Animation.RELATIVE_TO_SELF, 0.0f, Animation.RELATIVE_TO_SELF,
            -0.175f);
    mHiddenAction.setDuration(2000);
    move.startAnimation(mHiddenAction);
    mHiddenAction.setAnimationListener(new Animation.AnimationListener() {
        @Override
        public void onAnimationStart(Animation animation) {
        }

        @Override
        public void onAnimationEnd(Animation animation) {
            move.clearAnimation();
            ll_cour_weeks_gone.setVisibility(View.GONE);
            if (null != courseMeListResponse) {
                arrayWeek.get(Integer.parseInt(courseMeListResponse.getCurrentWeekNo()) - 1).performClick();//代码点击当前周
                tv_title_week_red.setVisibility(View.GONE);
            }
        }

        @Override
        public void onAnimationRepeat(Animation animation) {
        }
    });
}

其实就是view的上移动与下移动
