Android studio做中国象棋 等级1（简单单人操作）

相信大家也知道中国象棋是什么，这里我们直接上干货。

1、自定义view（用于绘制棋子）我上一篇文章已经讲过了，不了解的小伙伴可以点击查看，

2.好了，我们直接讲解中国象棋的制作过程

首先初始化一个二维数组的棋盘

int[][] qizi = {{3, 4, 5, 6, 7, 6, 5, 4, 3},{0, 0, 0, 0, 0, 0, 0, 0, 0},{0, 2, 0, 0, 0, 0, 0, 2, 0},{1, 0, 1, 0, 1, 0, 1, 0, 1},{0, 0, 0, 0, 0, 0, 0, 0, 0},{0, 0, 0, 0, 0, 0, 0, 0, 0},{8, 0, 8, 0, 8, 0, 8, 0, 8},{0, 9, 0, 0, 0, 0, 0, 9, 0},{0, 0, 0, 0, 0, 0, 0, 0, 0},{10, 11, 12, 13, 14, 13, 12, 11, 10}};

1：卒， 2：黑炮， 3：黑车， 4：黑马， 5：黑象， 6：黑士， 7：将 ，0：什么都没有

8：兵， 9：红炮，10：红车， 11：红马， 12：相，13：红士， 14：帅

相当于把屏幕分割成一个二维数组，然后根据数字摆放棋子

执行过程：点击屏幕 ——>判断点击位置是否有自己的棋子(是)——>选中该棋子——>

再次点击屏幕——>判断位置是否符合下棋规则（点击位置有对方棋子或空位）——>

可以移动，改变棋盘（数组）。
