更改背景颜色会影响儿童 [英] Changing the background color affects children

问题描述

我试图通过在主应用程序主题中添加一行来更改应用程序中的基本背景颜色:

I was trying to change the basic background color in my app by adding a single line to the main application theme:

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

我在做什么错了?

推荐答案

使用 android:windowBackground 代替 background 属性:

<item name="android:windowBackground">@android:color/white</item>
