需要如下调用才行：

@Overridepublic void dismiss() {Animation anim = AnimationUtils.loadAnimation(mContext, R.anim.up);anim.setAnimationListener(new SimpleAnimationListener() {@Overridepublic void onAnimationStart(Animation animation) {if (null != mOnAnimationDismissListener)mOnAnimationDismissListener.onStart();}@Overridepublic void onAnimationEnd(Animation animation) {new Handler().post(new Runnable() {@Overridepublic void run() {PopWindow.super.dismiss();}});}});mPopView.startAnimation(anim);}
