java - 如何为所有 Android 应用程序设置 Holo 灯光主题

Question

我不小心在布局中做了一些事情，现在我的所有 Activity 都是深色的，带有白色文本“在 TextViews 内”，之前所有 Activity 都是灰色带有黑色文本，当我在互联网上搜索时，我相信我以某种方式改变了从“Holo light”到“Holo dark”的所有 Activity ，如何恢复默认主题？

PS。我不认为问题出在布局上，因为我没有碰过它们。 附言。这是我的 list :

这是值文件夹内的 Styles.xml

<!--
    Base application theme, dependent on API level. This theme is replaced
    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.
    -->
</style>

<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
    <!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>

Answer 1

您已在 Activity 中设置了 android:theme="@android:style/Theme.NoTitleBar"，该样式将为您提供 Holo Dark 主题。

您必须将其替换为

android:theme="@android:style/Theme.Light.NoTitleBar"
