如何在Android中使用XML库引用的字符串从另一个包？ [英] How to reference a string from another package in a library using XML in Android?

问题描述

而Android 文档告诉我，我可以访问

The Android documentation tells me that I can access a string from another package by using the "package name", whatever that means:

@[<package_name>:]<resource_type>/<resource_name>

所以在我的清单我要访问，我已经放在一个单独的库项目的字符串，在 com.globalmentor.android包 ---这就是我的研究类的，毕竟：

So in my manifest I want to access a string that I've placed in a separate library project, in the com.globalmentor.android package---that's where my R class is, after all:

    <activity
        android:label="@com.globalmentor.android:string/app_applicationlistactivity_label"
        android:name="com.globalmentor.android.app.ApplicationListActivity" >
    </activity>

这还不编译。但这：

That doesn't even compile. But this does:

    <activity
        android:label="@string/app_applicationlistactivity_label"
        android:name="com.globalmentor.android.app.ApplicationListActivity" >
    </activity>

为什么呢？什么是Android的文件意味着它谈到了包名？为什么不第一例的工作，为什么没有第二个例子中工作？我不希望我所有的资源名称合并到同一个研究文件---我希望他们分成包，就像我写了他们。

Why? What does the Android documentation mean which it talks about the "package_name"? Why doesn't the first example work, and why does the second example work? I don't want all my resource names merged into the same R file---I want them partitioned into packages, like I wrote them.

推荐答案

在短期：包名preFIX是共享库，而不是为你的apk

In short: package name prefix is for shared libraries, not for your apk.

该文件内容如下：

要引用系统的资源，你需要包括包名

To reference a system resource, you would need to include the package name

这相当于外部共享库（及其资源），您的应用程序链接反对（如地图）。他们拥有自己的研发类，而不是与你的应用程序的合并。

This corresponds for external shared libraries (and their resources), your application is linked against (e.g. maps). They have their own R class, not merged with that of your application.

这些都是你的Andr​​oid清单部分所提到的所有标准的Andr​​oid包和共享库。

These are all standard android packages and shared libraries you mentioned in section of android manifest.

由于尼古拉指出，所有的应用程序资源合并，这就是为什么大多数库项目使用prefixes像abs__他们的资源名称。

As Nikolay pointed out, all app resources are merged, that is why the majority library projects use prefixes like abs__ for their resource names.
