最近做了一个调查问卷的东西，服务器返回的问题数，还有每个问题的选项个数都不固定，而且，有多选有单选，那数据结构整得我蛋疼。做好了，拿出来分享下
这个是联网的，所以代码中数据无法获取到。记录下来就是为了以后遇到类型的情况可以更熟练的搞定，因为一直对代码写布局不是很熟练
动态创建自己想要的布局流程我觉得应该这样
首先要在当前Context实例化一个需要的控件，找到要添加该控件的布局，addView该控件。如果要设置它的一些属性，可以通过LinearLayout.LayoutParams来做
一些其他的效果，就是靠这个控件的一些方法来搞了，什么设置文字，背景，焦点一些东西。之前我也做过类似的东西，就是搜索热词推荐，也是需要动态创建，
那时候迷迷糊糊的做完了，到现在都忘记了，这次巩固了一下。如果需要给控件加监听什么的，自己写个接口就好了，一定难不倒各位。

提交选项时，我需要相应RadioButton / CheckBox的信息，还有它们所对应的问题ID，所以就用了一个HashMap来装载，因为每个选项的ID信息是唯一的，那么就通过它来找到对应的问题ID，因为比较菜，想不出来有什么好的方法解决。我把动态创建的控件都放在了一个ScrollView中，效果是酱婶儿的
