从库项目的android进口ressources [英] android import ressources from library project

问题描述

是有可能使用ressources一样，在库项目中的应用程序项目定义字符串？如果是这样，怎么样？ 因为我似乎无法解析字符串我想解决这样的：

is it possible to use ressources like strings that are defined in library projects in the application-projects? if so, how? because i cant seem to resolve the strings i would like to resolve like this:

String title = "sample";
int id = ressources.getIdentifier(title, "string", "com.package");

给我这个异常

gives me this exception

WARN /的ResourceType（278）：没有包装标识的资源数量00000000获得价值时， WARN / System.err的（278）：android.content.res.Resources $ NotFoundException：字符串资源编号为0x0

WARN/ResourceType(278): No package identifier when getting value for resource number 0x00000000 WARN/System.err(278): android.content.res.Resources$NotFoundException: String resource ID #0x0

的字符串（样本），我期待的无疑是在库项目的strings.xml中提供了这个包。我甚至可以看到它在R.java

the string ("sample") i am looking for is definitely in this package provided in the strings.xml of the library project. i can even see it in the R.java

推荐答案

因此​​，它看起来像

INT ID = ressources.getIdentifier（标题，串，com.package）;

int id = ressources.getIdentifier(title, "string", "com.package");

在返回 0 ，这意味着它无法找到指定的资源。随后调用 ressources.getIdentifer（）引起的异常，因为 0 不是一个有效的资源ID。

is returning 0, meaning it can't find the specified resource. The subsequent call to ressources.getIdentifer() causes the exception, since 0 is not a valid resource id.

下面是一些调试/另类的想法：

Here are some debug/alternative ideas:

• 您可能已经这样做了十几次，但它不会伤害提：第一复检一切拼写：

• You've probably already done this a dozen times, but it doesn't hurt mentioning: first recheck spelling of everything:

• 在包的拼写是否正确（无论是在图书馆项目和客户项目），
• 在资源字符串是正确的（库项目和客户端项目），
• 是图书馆的拼写在正确的用途库元素中的的Andr​​oidManifest.xml ，
• 等

• package spelling is correct (both in library project and in client project),
• resource string is correct (library project and client project),
• is library spelling correct in the uses-library element the AndroidManifest.xml,
• etc.

• 您可以访问任何资源在库或问题特定于该资源（标题）或者是特定于该类型的资源（字符串）的？您可以访问其他库的资源？

• Can you access any resources in that library or is the problem specific to that resource (title) or is it specific to that type of resource(strings)? Can you access the resources of another library?

• 您访问的库作为一个jar文件？您可以罐子code，但你不能从一个罐子访问资源。

• 在你尝试备用名称格式为：

code

String fullyQualifiedResourceName = "com.package:string/sample";
int id = ressources.getIdentifier(title, null, null);
if (id == 0) {
    Log.e(TAG, "Lookup id for resource '"+fullyQualifiedResourceName+"' failed";
    // graceful error handling code here
}

• 您可以尝试使用反射：

• You could try using reflection:

code

final String resourceName= "sample";
final int id;
try {
    final Class resourceType = com.package.R.string.class;
    final Field field = resourceType.getField(title);
    id = field.getInt(null);
} catch (final Exception e) {
    Log.e(TAG, "Lookup id for resource '"+resourceName+"' failed";
    // graceful error handling code here
}
