####Android问卷调查类型页面及逻辑实现，RadioButton，CheckBox，EditView，RadioButton+EditView单选、多选、输入、单选加输入四种状态四种类型

问题简述：App做了一个类似问卷调查类型的功能，用来调研投票用的，RadioButton单选，CheckBox多选，EditView输入，RadioButton+EditView单选加输入四种类型，刚开始做遇到跟多坑，RecyclerView+item+LinearLayout+RadioGroup试了一下，RadioGroup有一点不可描述的问题，我就换成RecyclerView+item +RecyclerView+item+RadioButton了，主要是单选不好搞，输入和多选还可以，还是没搞定，因为过于相信RecyclerView的强大，最后才试的LinearLayout动态添加布局，然而发现还是不行o(╥﹏╥)o，第一次展示的时候没问题，基本都是选择完问题第二次回拉的时候单选框不在选中状态了，最后在大佬的帮助下才得以解决，网上资料比较少，特意做一下记录。
