    by AppBaseTheme from res/values-vXX/styles.xml on newer devices.

<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
    <!--
        Theme customizations available in newer API levels can go in
        res/values-vXX/styles.xml, while customizations related to
        backward-compatibility can go here.

    <item name="actionMenuTextAppearance">@style/MyMenuTextAppearance</item>
    <item name="android:actionMenuTextAppearance">@style/MyMenuTextAppearance</item>
</style>

<style name="MyMenuTextAppearance" parent="TextAppearance.AppCompat.Widget.ActionBar.Menu">
    <item name="android:textAllCaps">false</item>
</style>


@样式/MyMenuTextAppearance
@样式/MyMenuTextAppearance
假的

检查此链接我已经阅读了上述答案,但在api级别21以下的AppBaseTheme主题中添加false,在api级别21及以上的主题中添加false不起作用。尝试了此allso,但不起作用错误报告的false投票。。。
