}|code-block|syntax|javascript|2574731|}|2574732|正如您所看到的，它们是如何生成的有一种模式。每一类资源都有自己的工作领域。|2574733|另一件要注意的事情是，它们是按照它们在XML+/文件夹/等中遇到的顺序生成的。因此，例如，如果您在XML中移动一些视图，您将需要清理项目以重新生成完整的R.java文件。否则，整数映射将是不正确的，您将(最有可能)得到一个ClassCastException，或者至少是意外的行为。|2574734|entityMap^0|9|3|I|6|0|0|0|0|24|6|33|I|0^^$0|@$1|2|3|4|5|6|7|S|8|@$9|T|A|U|B|C]|$9|V|A|W|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|X|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|Y|8|@]|D|@]|E|$]]|$1|M|3|N|5|6|7|Z|8|@]|D|@]|E|$]]|$1|O|3|P|5|6|7|10|8|@$9|11|A|12|B|C]|$9|13|A|14|B|C]]|D|@]|E|$]]|$1|Q|3|-4|5|6|7|15|8|@]|D|@]|E|$]]]|R|$]]

The integers are stored in a generated file called <code>R.java</code> in the project's <code>gen</code> folder. A sample from a recent work-in-progress of mine is:

<pre><code>public final class R {
public static final class attr {
}
public static final class drawable {
 public static final int cot_logo=0x7f020000;
 public static final int cot_logo_small=0x7f020001;
 public static final int ic_launcher=0x7f020002;
 public static final int icon=0x7f020003;
}
public static final class id {
 public static final int password=0x7f060001;
 public static final int username=0x7f060000;
}
public static final class layout {
 public static final int login_dlg=0x7f030000;
 public static final int main=0x7f030001;
}
public static final class string {
 public static final int app_name=0x7f050000;
}
public static final class xml {
 public static final int config=0x7f040000;
}
</code></pre>

}

As you can see, there is a pattern to how they are generated. Each category of resource is given its own area to work with.

Another thing to note is that they are generated in the order they are encountered in the XML/folders/etc. So, for example, if you move some views around in the XML, you'll need to clean your project to regenerate the full <code>R.java</code> file. Otherwise, the integer mappings will be incorrect and you'll end up with(most likely) a <code>ClassCastException</code>, or unexpected behaviour at the very least.

blocks|key|2574767|text|要理解这些数字是如何生成的，您需要了解aapt是如何工作的，因为该工具负责生成R.java。您可以使用git克隆Android存储库并检查aapt源代码，但这相当复杂(至少对我来说是这样)。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|CODE|entityRanges|data|2574768|如果你想查看代码，首先克隆源代码：|2574769|git+clone+"https://android.googlesource.com/platform/sdk"|code-block|syntax|javascript|2574770|然后导航到src/com/android/ide/eclipse/adt/internal/build，这是aapt相关源代码所在的位置。|2574771|entityMap^0|J|4|13|6|0|0|0|5|1A|0^^$0|@$1|2|3|4|5|6|7|R|8|@$9|S|A|T|B|C]|$9|U|A|V|B|D]]|E|@]|F|$]]|$1|G|3|H|5|6|7|W|8|@]|E|@]|F|$]]|$1|I|3|J|5|K|7|X|8|@]|E|@]|F|$L|M]]|$1|N|3|O|5|6|7|Y|8|@$9|Z|A|10|B|D]]|E|@]|F|$]]|$1|P|3|-4|5|6|7|11|8|@]|E|@]|F|$]]]|Q|$]]

To understand how those numbers are generated you will need to find out how aapt works because that tool is responsible for generating the <code>R.java</code>. You can git clone the Android repository and check the aapt source code but It's quite complicated (at least for me).

If you want to see the code, First clone the source:

<pre><code>git clone "https://android.googlesource.com/platform/sdk"
</code></pre>

Then navigate to <code>src/com/android/ide/eclipse/adt/internal/build</code>, This is where aapt related sources are.

I was wondering how the Android resource identification system works.

So, I have (for example) a XML layout file with the name "example".
In my java code, this is identified by calling R.layout.example which
returns an integer.

What I was wondering was how this integer is determined, and then how
an integer value is used to identify and find a corresponding resource.

Thanks!

How are resource identifier values determined in Android?

我想知道Android资源识别系统是如何工作的。因此，(例如)我有一个名称为"example“的XML布局文件。在我的java代码中，这是通过调用返回整数的R.layout.example来标识的。我想知道的是这个整数是如何确定的，然后如何使用整数值来标识和查找相应的资源。谢谢!
