五子棋 手打稍加改变自慕课网hyman

我整理了一下,顺便加了一点屏幕切换的代码,网速太不给力,好几次都坑了

直接上代码吧,稍后总结,简单粗暴,详情看题目

好了没有什么遗漏了.

总结下 自定义view的 步骤 思路:

1. 编写xml布局
2. 初始化测量 onMeasure 方法, onSizeChange()方法–初始化尺寸,
3. 初始化 棋盘
4. onTouch时间处理 down 的时候返回ture,表示我对这个触摸事件感兴趣,我要处理
5. 绘制旗子 –
6. 逻辑判断.三点 1 gameover 和 一个位置不可重复放子.2 在某个范围内 都下在 网格中心点上
7. view的存储and恢复
8. 再来一局
9. 其他 屏幕尺寸改变需要注意的事项

备注: 自定义view的思路完全是自上而下的
