设置内容菜单的View
BottomPopupWindowView.setContextView(bottomView);
设置没有显示菜单时候显示的View(注:bottomView的高度要和BottomPopupWindowView的高度一样，具体看demo)
BottomPopupWindowView.setBaseView(bottomView);
设置动画监听放回的数据，以便根据数据实现动画
BottomPopupWindowView.setAnimatorListener(new AnimatorListener() {
    @Override
    public void startValue(int value) {
        Log.e("value",value+"");            
    }
    @Override
    public void endValue(int value) {
        Log.e("value",value+"");          
    }
});
