最近在写安卓APP时需要用到弹出式菜单，系统内置的弹出式菜单有些不和谐，原本的导航菜单都有图标和复选按钮，但是变成弹出式菜单后都没有了，网上找了一个部分解决图标问题，但是这仅能解决图标问题，复选按钮，分割条这些都美没有的，看起来一堆，不爽，后来参考了一些自定义弹出式菜单，自己写了一个弹出式菜单类，个人感觉用起来还不错，这里将源码分享出来。主要用了弹窗类的实现吗，共两个类文件。完整代码如下：

主要调用DropMenu类下的构造方法构造实体，调用如下：
mDropMenu=new DropMenu(this,btnPopMenu); //this为河东窗体上下文；btnPopMenu需要将菜单弹出的定位视图（以该视图为圆点定位）
//添加菜单项
mDropMenu.addMenuItem("cshqx","初始化曲线",R.drawable.ic_timeline_black_24dp,true,true);
mDropMenu.addSplitLine();
mDropMenu.addMenuItem("gxzqd","更新主驱动",R.drawable.ic_play_for_work_black_24dp,false,false,true);
mDropMenu.addMenuItem("wd","我的",R.drawable.ic_account_circle_black_24dp,false,false,false);
调用DropMenu的show()方法弹出菜单。效果如下：
