3.2.5. R文件

3.2.5.R文件

R文件负责Java与外部资源之间的关联。它在res目录中的内容发生变化时(比如添加一个图片或者xml文件)由SDK自动生成，不必也不应该手工修改。

既然有Eclipse代劳，对这个文件本身我们不必关注太多。不过它里面的数据是非常有用的。

例 3.4. gen/com/marakana/R.java

/* AUTO-GENERATED FILE. DO NOT MODIFY.

*

* This class was automatically generated by the

* aapt tool from the resource data it found. It

* should not be modified by hand.

*/

package com.marakana;

public final class R {

public static final class attr {

}

public static final class drawable {

public static final int icon=0x7f020000;

}

public static final class layout {

public static final int main=0x7f030000;

}

public static final class string {

public static final int app_name=0x7f040001;

public static final int hello=0x7f040000;

}

}
