双击编辑文本字段时，Android 应用程序崩溃

Question

我正在使用操作栏模板开发一个安卓应用程序。一切正常，但是当我双击任何 EditText 字段时，应用程序出现运行时错误，并且它崩溃了。当我只点击一次时，什么也没发生，一切都很好。这是布局（片段）

    </GridLayout>
</RelativeLayout>

我可以触摸该字段，更改其值，没问题，只需双击它时，应用程序崩溃，在日志上留下以下错误消息：

有什么解释吗？

Answer 1

您的问题不在于您的 xml 布局，而是因为 android ActionMenuItemView xml 布局，它无法处理您通过 Java 代码应用于它的自定义，因此您在膨胀操作栏菜单项时犯了一些错误，请查看此处以了解您忘记了什么或错过了什么。
