Java EclipseAndroid SDK中的自动完成问题

java android eclipse

Java EclipseAndroid SDK中的自动完成问题,java,android,eclipse,Java,Android,Eclipse,我正在使用Ubuntu 12.04中的eclipse编写Android应用程序。几天以来，我在自动完成功能上遇到了一个非常奇怪的问题：当我点击ctr+space时，eclipse像往常一样显示了所有的可能性。但如果我选择其中一个并按enter键，它通常不会做任何事情（在某些情况下，它会正常工作）。例如，如果我键入'find'并点击ctr+空格，它将显示'findViewById（）'和'FindListener'的可能性。如果我选择Findlistener，自动完成就可以了，但是如果我选择fin

我正在使用Ubuntu 12.04中的eclipse编写Android应用程序。几天以来，我在自动完成功能上遇到了一个非常奇怪的问题：当我点击ctr+space时，eclipse像往常一样显示了所有的可能性。但如果我选择其中一个并按enter键，它通常不会做任何事情（在某些情况下，它会正常工作）。例如，如果我键入'find'并点击ctr+空格，它将显示'findViewById（）'和'FindListener'的可能性。如果我选择Findlistener，自动完成就可以了，但是如果我选择findViewById，eclipse什么都不做，除了（有时）在Linux终端中抛出以下异常：

我已经尝试过解决问题的方法： -创建一个新的工作区 -重新安装Android插件 -重新安装eclipse -更改内容辅助的设置，然后恢复默认设置 -从Android SDK管理器重新安装所有软件包
有人知道我如何解决这个问题吗？如有任何建议，我将不胜感激。谢谢你

我正打算建议放弃旧的工作区并创建一个新的工作区。有了ADT插件，我很少能在大量问题阻止我工作之前，保持同一个工作区超过2天。似乎它没有解决您的特定问题。
