//该方法返回的是一个View的对象，是布局中的根

//下面我们要考虑了，我怎样将我的layout加入到PopupWindow中呢？？？很简单
menuWindow = new PopupWindow(layout, RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.WRAP_CONTENT); //后两个参数是width和height
//menuWindow.showAsDropDown(layout); //设置弹出效果
//menuWindow.showAsDropDown(null, 0, layout.getHeight());
menuWindow.showAtLocation(this.findViewById(R.id.activity_main), Gravity.BOTTOM|Gravity.CENTER_HORIZONTAL, 0, 0); //设置layout在PopupWindow中显示的位置
//如何获取我们main中的控件呢？也很简单

//下面对每一个Layout进行单击事件的注册吧。。。
//比如单击某个MenuItem的时候，他的背景色改变
//事先准备好一些背景图片或者颜色
