本文实例讲述了Android动态添加设置布局与控件的方法。分享给大家供大家参考，具体如下：
有时候我们会在代码端，动态的设置，添加布局和控件。下面我们就看来看一下如何处理，直接上代码，代码里面的注解很清楚了。
布局文件：fragment_hot.xml
说明：这个部局，我用的是scrollView做为基础布局，主要是为了实现一个滚动。这里不多说，这个你可以使用任何布局都可以，这里的id我是提前定义的。
这里面的现在有的布局是我为了看到我在代码端，动态添加的代码，是否可以追加到现有布局的后面而加上，这里大家可以自己设置
一个背景图文件在drawable文件夹中
rectangle_radius_fen.xml
说明：很简单，就是设置一个有圆角的方形
后台代码：
fragment_hot.java
说明：这里不多说了，里面的注解很明确了

希望本文所述对大家Android程序设计有所帮助。
