🔥老规矩，先上效果图

🔥需求分析

实现扫雷高级版，高级版有30*16的网格，480个格子，99个地雷，381个安全区，通过以下操作逻辑完全避开99个地雷视为通关，可使用小红旗最大数量为99个！

操作逻辑：

单次长按插小红旗，第二次长按填问号，再次长按恢复正常状态单次点击进行开疆扩土，踩到地雷本局游戏结束，并显示所有地雷当所有雷排干净时，游戏胜利！

🔥实现分析

分配2个地图二维数组，一个是雷区，一个是用户操作图

当用户操作是，判断点击位置，上下左右，以及周围的角，进行扩展

当用户第一次点击时，才是创建雷区的时候，防止用户点击上来就炸！！！

通过递归的方式查询，判断周围雷区，开疆扩土！

话不多说，源码开始！！！

🔥代码实现

代码实现开始了！

MinefieldUtil

公共地图类，这个类承担的作用，如下注释，包含创建，分配地图等，注释写的很详细了，可以直接看：

RcAdapter

地图适配器，这是一个RecyclerView的适配器，直接用RecyclerView写的，作用是显示地图以及赋予点击事件：

MainActivity

第一个启动的页面，作用于创建实例！通过它来调用上述两个类来实现的，其功能也写了很详细的注释！可以直接看下面：

综上所述，完成基本靠以上3个类，这是主要逻辑代码！
