【背景】
折腾：
【记录】Android中在Tab页面的Group中显示各种类型的控件
期间，需要去动态在TAB页面内的Group内，
动态的创建一个个label：value的形式的组合。
并且最好在最开始再加上一个status的图标的前缀：
[status]label: value
【折腾过程】
1.后来看到这个：
Android textview usage as label and value – Stack Overflow
这个很像我需要的：
只是不需要其中的竖杠。
而帖子中是通过静态的xml去实现的，但是我希望是动态创建的。
先去参考试试，看看静态的能否创建出来所需要的效果，如果可以，再考虑改为动态创建。
2.算了，还是自己代码中，随便去试试吧。。
截止目前，还是没有实现出所需要的效果，只是凑合的使用这样的代码，加上自己随便弄点数据：

生成如下的效果：
和：
【总结】
总之是：
group内部的每个label和value部分，还是没有实现真正想要的，对其的效果。
看来要等以后抽空再去想办法，通过GridLayout去实现Group内部的对其的效果了。
