主题中的 colorPrimary 和 colorPrimaryDark 有什么区别 [英] What is the difference between colorPrimary and colorPrimaryDark in themes

问题描述

我正在尝试了解该主题在 android 中的工作原理.我不知道为什么 colorPrimaryDark 对我不起作用，或者我做错了.

I'm trying to understand how the theme works in android. I don't know why colorPrimaryDark won't work with me or maybe i'm doing it wrong.

我尝试了这个设置，但由于 colorPrimary，我的操作栏变成了红色:

I tried this set and my action bar turns red because of colorPrimary:

<style name="MenuTheme" parent="Theme.AppCompat.Light.DarkActionBar">
  <item name="colorPrimary">#FF0000</item>
  <item name="colorPrimaryDark">#0000FF</item>
  <item name="colorAccent">#00FF00</item>    
  <item name="actionMenuTextColor">#0000FF</item>
</style>

我试图删除 colorPrimary 并且它变成黑色(我认为它会因为 colorPrimaryDark 而使用蓝色:

I tried to remove the colorPrimary and it turns black (which I thought it will use blue because of colorPrimaryDark:

<style name="MenuTheme" parent="Theme.AppCompat.Light.DarkActionBar">
  <item name="colorPrimaryDark">#0000FF</item>
  <item name="colorAccent">#00FF00</item>    
  <item name="actionMenuTextColor">#0000FF</item>
</style>

我尝试删除 colorPrimaryDark 并留下 colorPrimary 并且它再次变为红色:

I tried to remove the colorPrimaryDark and left the colorPrimary and it turns red again:

<style name="MenuTheme" parent="Theme.AppCompat.Light.DarkActionBar">
  <item name="colorPrimary">#FF0000</item>
  <item name="actionMenuTextColor">#0000FF</item>
</style>

我不知道我是否以错误的方式使用它，或者它根本没有真正改变.谁能告诉我它们之间的区别?

I don't know if i'm using it in wrong way or it's not really changing at all. Can anyone tell me the difference among them?

我还尝试了 actionMenuTextColor 来更改 actionBar 中的文本颜色，但没有任何反应.我找到了使用 parent="Theme.AppCompat.Light.DarkActionBar" 而不是 parent="Theme.AppCompat.Light" 单独的解决方案.但当然它只会变成白色.如果有任何办法，我仍在尝试将其改成不同的颜色.

I also tried actionMenuTextColor to change the text color in actionBar but nothing happened. I found out the solution using parent="Theme.AppCompat.Light.DarkActionBar" instead of parent="Theme.AppCompat.Light" alone. But of course it will only turn into white. I'm still trying to make it in different color if there is any way.
