我正在使用 Action Bar 模板开发一个 android 应用程序。一切正常，但是当我双击任何 EditText 字段时，应用程序会出现运行时错误，然后崩溃。当我单击一次时，什么也没有发生，一切都很好。这是布局（片段）

</RelativeLayout>

我可以触摸该字段，更改其值，没有问题，只是当我双击它时，应用程序崩溃，并在日志中留下以下错误消息：

有什么解释吗？

您的问题不在您的 xml 布局中，而是由于 android ActionMenuItemViewxml 布局，它无法处理您通过 Java 代码应用到它的自定义，因此您在扩展操作栏菜单项时犯了一些错误，请看这里了解您忘记了什么或错过了什么。
