有时候我们想在标准的Framework中添加自己的新的资源怎么办呢？
办法就是我们来尝试下。
通过Eclipse的联系，我们可以联想到是否就是简单的把字符串放在res的各个文件夹里面。先来试试看，编译，系统立即报错。为什么呢？
它提示你利用make update-api这个命令来更新public.xml文件或者把这个声明称hide类型。这个肯定不是我们想要的。
所以方法有二：
方法1：正常添加完资源后，执行make update-api函数。系统更新res/values/public.xml文件。
方法2：正常添加完资源后，手动更改/res/values/public.xml文件。打开public.xml文件。发现结构如下：
复制代码 代码如下:
<resources>
<!-- We don't want to publish private symbols in Android.R as part of the
SDK. Instead, put them here. -->
<private-symbols package="com.android.internal" />
<!-- AndroidManifest.xml attributes. -->

这样，我们可以自己动手添加。
推荐方法1，也是最标准的做法。为啥？
1：避免id重复。
2：麻烦
3：习惯标准化做法。
