seletctAll___利用ScrollView+RadioGroup+RadioButton实现相似互斥-优快云博客

本文链接：https://blog.youkuaiyun.com/aliusa/article/details/83914667

假如你有多个匹配list,在这些匹配list中存在这样的一些匹配条目
a 匹配 b；
a 匹配 c；
a 匹配 d；

e 匹配 f
d 匹配 g；
加入你要实现实现select all，但有想实现相似条目互斥功能，
互斥的意思是：在上述条目中有关a的三个条目之间匹配条目只能存在一个，也就是
如果选择了
a 匹配 b，
那么a 匹配 c；
a 匹配 d；就自动把check状态值为false，
那么可以参照如下方式实现：
