Eclipse内容辅助错误

Question

最近我在Eclipse中的内容辅助方面遇到了越来越多的问题。在我的一些项目中，我没有从内容协助中获得任何提议，而在其他项目中，我得到了部分或全部预期提案。通常，Eclipse中没有“错误”，但是当我收到错误时，这是​​一个例子：

  

“内容辅助”未正常完成。有关更多信息，请参阅日志。   Pb（324）无法解析android.support.v4.app.LoaderManager $ LoaderCallbacks类型。它是从所需的.class文件间接引用的

我已尝试过类似问题的各种建议（包括但不限于以下两项），但没有运气。我甚至没有删除和重新安装eclipse并重新创建项目而没有任何Eclipse元数据或设置。

• Eclipse Content Assist not working with Android
• Eclipse/Java code completion not working

非常感谢任何帮助。

Answer 1

试试这个

窗口＆gt;＆gt;偏好设置＆gt;＆gt; Java＆gt;＆gt;编辑器＆gt;＆gt;内容辅助＆gt;＆gt;恢复默认值

窗口＆gt;＆gt;偏好设置＆gt;＆gt; Java＆gt;＆gt;编辑器＆gt;＆gt;内容辅助＆gt;＆gt;高级＆gt;＆gt;恢复默认值

Answer 2

我最终将ActionBarSherlock库升级到最新的4.1（http://actionbarsherlock.com/）并修复了我的日食问题。

Answer 3

我在更新时使用V4兼容库的项目遇到了类似的问题。尝试删除对库的项目依赖，重新启动Eclipse，然后重新添加依赖项。（我认为这是我为解决问题所做的，但如果这不起作用，我'我会试着想一想我可能做了什么。）

Answer 4

我也有这个问题，有Pb（324）消息。事实证明，阅读信息的理解足以解决它。然而，我首先做的是stackoverflow。没有好处:)）

在我的groovy项目中，自动完成不会自动显示依赖库。不知道为什么，我对这个东西不熟悉。所以我手动添加它们。但我没有手动添加间接依赖项。错误消息指定导致问题的类。 我添加了对包含有问题的类和bingo的jar的引用 - 不再有代码辅助错误。

具体：项目，属性，Java构建路径，库，添加外部JAR 。然后我指向了gradle下载lib的目录。

Answer 5

对我来说，更新Eclipse有用。
