每当我尝试在findViewById（）上使用内容辅助时，代码都无法完成。它只是保持不变。当我查看错误日志时，它会显示：

我在Eclipse-Juno上。我有时使用View.onClickListener内容辅助来获取此错误。但错误发生的次数较少。错误日志还显示负责的插件是org.eclipse.ui。但是，我没有在我的eclipse / plugin文件夹中看到该插件。我只看到org.eclipse.ui.intro.universal_3.2.600.v20120912-155524
此外，在为View.onClickListener内部类型使用内容辅助时，我也会收到“未处理的事件循环异常”。
我发现了一个类似的问题。它被报道为日食中的一个错误。这是链接：
答案 0 :(得分：0)
我明白了！我将eclipse文件夹移动到另一个位置（我的桌面）和BOOM！没有更多错误！我设法使用内容辅助而不返回“未处理的事件循环异常”。也许位置上挤满了太多文件。
