在网上搜了非常长时间。没有找到合适的Android三级菜单。所以就自己动手写了一个，主要使用了BaseExpandableList来实现，通过三个布局文件来完毕相应的菜单项，详细实现请參照下图。

watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQva2FpNDYzODUwNzY=/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/Center" width="300" height="600" alt="">

通过上面两图能够看出为三级菜单，每个菜单相应一个实体类，能够通过json解析数据载入进来，这里就只是多解释了。直接上源代码！

Activity实现类：
