基于Android的数独游戏-----用Java语言编写

1、在src中有4个Java类：

其中代码分别是：

3、values中的配置文件

就只有color.xml是自己写的，另外三个都是自动生成

color.xml

<?xml version="1.0" encoding="utf-8"?><resources>        <color name="shudu_background">#ffe6f0ff</color>    <color name="shudu_dark">#64ff0000</color>    <color name="shudu_light">#64ffffff</color>    <color name="shudu_hilite">#6400ff00</color></resources>
