【发布时间】：2016-03-18 23:14:20
【问题描述】：

所以我刚刚构建了一个应用程序，但顶部是一个白条。我相信它是 ActionBar，但每次更改颜色的尝试都不起作用。关于如何删除它或改变它的颜色的任何想法？谢谢

【问题讨论】：

在活动或片段上？ @格雷格·威廉姆斯
没关系，我只是看到了它的一项活动。继续您的清单并在主要活动下定义应用程序主题。应该是这样的。 android:theme="@style/NoActionBar"
这不起作用，它仍然显示顶部的白条
我知道您尝试过我发布的答案但没有用吗？
@Salvatory Baya 添加了 LogCat 输出，我假设它是一个 ActionBar；如何确认它是 ActionBar 还是 StatusBar？

标签： android xml webview android-actionbar

【解决方案1】：

问题出在您的样式 v-21 文件中

<resources>
<style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
    <item name="android:windowDrawsSystemBarBackgrounds">true</item>
    <item name="android:statusBarColor">@android:color/transparent</item>
</style>
</resources>

改变这一行

<item name="android:statusBarColor">@android:color/transparent</item>

将 '@android:color/transparent' 更改为其他颜色

【讨论】：

没有用，它使应用程序崩溃。我尝试了'@android:color/primary_text_dark`和@android:color/background_dark
您可以通过单击答案旁边的“打勾”将我的答案标记为“已接受”:) 很高兴我能帮助您。另一件事-您用于状态栏的任何颜色都可能不会在旧版本的 android 中使用，因此请在 api 上测试您的应用
我将颜色配置为：@color/colorPrimaryDark，它的外观与具有 nav_draw 模型的主要活动相同。
