这篇文章给大家分享的是有关Android自定义View实现数独游戏的方法的内容。小编觉得挺实用的，因此分享给大家做个参考，一起跟随小编过来看看吧。
先说一下数独游戏的规则：
1.在整个横坐标和纵坐标的9个格子上只能填土1-9的数字且不重复
2.在当前3*3 的格子上填入1-9数字且不重复
先给大家看效果图
项目思路
1、UI呈现：这个放在 GameView 类里面
显示原始数据
显示当然用户填写的数据
显示用户当前点击的位置
显示候选区数据
2、逻辑处理：这个是放在Matrix类里面的
原始数据：游戏开始的时候就要创建出来的，
当前数据：用户填写上去的实时数据
数据判断：判断这个位置可以修改数据吗？ 比如，原始数据就是不可以修改的
判断这个位置可以填入的数据，比如，原始数据这个位置有8了，就不能填8了。
代码 GameView 类
