我现在正在制作 4 名球员的记分卡，用户在页面底部输入 4 名球员的分数，当按下 + 按钮时，刚刚输入的分数将添加到上面的滚动视图中。
slot number 定义为整数，这样当用户在对应的 EditText 中输入 1、12、34、56、78 时，app 可以识别并添加一行 slot =1，则 Player 1 得分为 12，玩家 2 为 34，P3 = 56，P4 = 78。
然后当用户输入另一个集合，如 2、23、45、67、89 时，它将添加为第 2 轮，依此类推。至此行可以正常添加，槽号可以是1、2、3等等，但是不知道为什么
第 1 轮：槽号正确为 1，但上面输入的所有 4 名玩家得分都变为 78，
第 2 轮：插槽号正确为 2，但上面输入的所有 4 名玩家得分都变为 89。
