Question

我想在我的Mono For Android项目中绑定ActionBarSherlock的jar库。我对此文档表示赞赏：http://docs.xamarin.com/android/tutorials/Binding_a_Java_Library_(.jar)

我已经成功绑定了ActionBarSherlock所需的android-support-v4.jar。但是当我尝试编译actionbarsherlock.jar时，它给出了以下错误消息：

对于android-support-v4.jar，我找到了这些xml文件并将它们放在Transforms目录中：

Answer 1

ActionBarSherlock包含无法编译成JAR文件的UI元素，样式和其他内容。 ActionBarSherlock FAQ上有关于此的说明。

问：为什么ActionBarSherlock是一个库项目而原始兼容库只是一个.jar？

答：ActionBarSherlock中的自定义操作栏实现依赖于样式，主题，布局和drawable，以便正确显示。由于Android和.jar文件的限制，目前无法以任何其他方式完成。

修改：在此链接中，有一些关于尝试在Mono for Android中跨库项目共享资源的其他信息：http://mono-for-android.1047100.n5.nabble.com/Resources-from-a-Library-Project-td4657828.html。简短的回答是目前看起来不可能。

Answer 2

我相信我已成功将ActionBarSherlock绑定在Mono for Android中。

您需要将java文件打包为JAR文件，但不包含资源且没有R java类文件。在打包文件之前，请确保选中Android设置中显示“Is Library”的框，以便资源ID不会创建为常量并在已编译的java类中内联。

完成此操作后，您可以使用最新版本的Mono for Android来绑定JAR文件。

资源需要与JAR文件分开复制并直接放在主Android应用程序项目中。不幸的是，目前在使用Mono for Android时没有办法在单独的库项目中隔离资源，但我预计很快就会改变。

最后，您需要编辑C-Sharp项目文件，以便每次重建时自动创建新版本的com.actionbarsherlock.R java类文件。这是保持所有资源ID同步所必需的。

我可能错过了一两步，但那些是最重要的。

Answer 3

这可能看起来像一个大锤的方法，但可能会解决你的问题......

我建议使用Maven构建，它可以更好地处理这些依赖关系。您将能够在POM中引用ActionBarSherlock项目，MVN将为您管理依赖项。

我也可以确认原始答案是正确的 - 包含包含布局资源的JAR文件是有限制的。

Answer 4

看起来Xamarin解决了ActionBarSherlock绑定问题

https://bugzilla.xamarin.com/show_bug.cgi?id=6186

此修复程序已包含在4.2.5中，现在可在Alpha通道上使用。
