我有一个问题，但没人能帮助我。问题是： 我有详细的活动以显示我的产品的详细信息。 此活动具有一个白色背景的工具栏（相对布局）。 一切都很好，没有问题，但是当我从片段到细节活动时，我的工具栏颜色变成了蓝色！ 我尝试检查是什么原因，最后我发现我的应用程序不知道白色！！如果我使用#ffffff（硬编码或从资源获取），我的工具栏会变成蓝色，但是如果使用其他任何颜色，即使#fffffe
也可以这是我的风格

答案 0 :(得分：2)
什么是样式中的活动主题，如果您未设置noActionBar主题，则android会将默认工具栏放在相对布局上，而您看不到它
因此定义您的样式
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">@color/activityBackground</item>
<item name="colorPrimaryDark">@color/greyTextColor</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
并将AppTheme.NoActionBar栏主题设置为您在AndroidManifest文件中的活动 或使用
<style name="AppBaseTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
</style>
答案 1 :(得分：1)
尝试使用-
android：background =“ @ android：color / white”
答案 2 :(得分：1)
您可能想尝试一下；为“ colors.xml”定义一种新颜色，并将其用作背景。
更新
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
您应使用所需的颜色更改@color/colorPrimary和@color/colorPrimaryDark。用颜色定义它们并分配它们，而不是上面的两个。它必须是固定的。祝你好运！
答案 3 :(得分：1)
您有两种选择
1）您可以在onCreate的明细活动中设置工具栏颜色
toolbar.setBackgroundColor（Color.WHITE）;
检查这是否可行或
2）在color.xml中设置白色并从那里获取参考
“
检查任何一项，如果不行，请通知我。
