AppCompat 弹出菜单 RuntimeException
AppCompat PopUp menu RuntimeException
我正在使用以下 class 创建图标化弹出菜单：

但是，如果我尝试在 lolipop 上 运行 它会导致错误。它在 API 级别 < 21 的设备上工作正常。这是 logcat:

activity 使用此扩展 Activity，而不是 ActionBarActivity。知道为什么会产生错误吗？
感谢转发
编辑： 我试过使用默认的 appCompat PopUp 菜单（所以它没有图标）并且它抛出了同样的错误。有什么想法吗？
这似乎是样式属性丢失或更改的问题，如
所示
Caused by: java.lang.RuntimeException: Failed to resolve attribute at index 6
02-15 06:08:09.165: E/AndroidRuntime(3824): at android.content.res.TypedArray.getLayoutDimension(TypedArray.java:603)
内部 android 在本地主题上下文中使用 ?attr/ 查找样式属性。
尝试调试恰好发生这种情况的代码行，以找出缺少哪种样式。
我找到了解决方案。唯一的问题是我在 values-v21/styles.xml
中有以下声明
<style name="AppTheme" parent="android:Theme.Material.Light">
</style>
所以我改成了
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
</style>
现在效果很好。
在这种情况下 MenuPopupHelper.MenuAdapter#getView() try to inflate ITEM_LAYOUT = R.layout.abc_popup_menu_item_layout and during this process android.support.v7.internal.view.menu.ListMenuItemView 创建并要求
R.styleable.MenuView (look inside to find - declare-styleable name="MenuView") where attribute at index 6 is attr name="android:itemIconDisabledAlpha" this mean that no this attribute defined in application theme. Required attribute defined in <style name="Theme"> for any platform as <item name="disabledAlpha">0.5</item> this is link。
要使用默认值，只需通过扩展 <style name="Theme">.
的主题之一扩展应用程序主题
我推荐以下解决方案：
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
</style>
或任何其他带有 NoActionBar 的 Theme.AppCompat
如果您想将 Toolbar 用于早于 v21 的平台，所有新功能都可以作为 ActionBar 组件的替代品。
但如果确实需要，实际上可以随意使用其他主题，例如 Holo 或 Material。
祝你好运！
