我发现了一个解决方案，它似乎工作。首先，你需要在attr.xml定义自定义颜色域

 ＆LT; XML版本=1.0编码=UTF-8＆GT？;
＆LT;资源＆GT;

＆LT; attr指示NAME =titleColor格式=引用|色/＆GT;
＆LT; attr指示NAME =introColor格式=引用|色/＆GT;

＆LT; /资源＆GT;
 

下面定义你的主题

 ＆LT;样式名称=AppTheme.MyDark父=安卓主题＆GT;
   ＆LT;项目名称=titleColor＆GT;＃FFFFFF＆LT; /项目＆GT;
   ＆LT;项目名称=introColor＆GT;＃FFFFFF＆LT; /项目＆GT;
＆LT; /风格＆GT;


＆LT;样式名称=AppTheme.MyLight父=安卓主题＆GT;
   ＆LT;项目名称=titleColor＆GT;＃000000＆LT; /项目＆GT;
   ＆LT;项目名称=introColor＆GT;＃004444＆LT; /项目＆GT;
＆LT; /风格＆GT;
 

终于在布局

 ＆LT;的TextView
    机器人：ID =@ + ID / quoteTitle
    机器人：titleColor文字颜色=
    ...
＆LT; / TextView的＆GT;

＆LT;的TextView
    机器人：ID =@ + ID / quoteIntro
    机器人：introColor文字颜色=
    ...
＆LT; / TextView的＆GT;
 

我找到了解决办法主要是here

似乎有关于使用属性Android官方文档中没有解释。我发现***的资源是这里

I am sure there is a simple answer to that yet I just cant find it so I throw it into *** ... ;-)

I will just put it into an example. I have an android app where the user can choose the theme in the preferences - dark or light theme. Depending on the chosen theme I have to adjust 20 colors in my app. So I have the hope that I can define colours in the theme and then use the names of this so defined colours in the my TextViews etc. Yet so far I cant figure out how to do that and can't find any solution here and there. I really dont want to define an extra dark and light style for each of these 20 colours yet so far that seems the only solution I can find.

Big thanks for any hint

UPDATE:

In pseudo syntax is that is what I am looking for. Is it possible?

<style name="AppTheme.MyDark" parent="android:Theme">
  -?-> titleColor = "#ffffff"
  -?-> introColor = "#ffaaaa"  
</style>

<style name="AppTheme.MyLight" parent="android:Theme.Light">
  -?-> titleColor = "#000000"
  -?-> introColor = "#004444"  
</style>


<TextView
        android:id="@+id/quoteTitle"
        android:textColor=@titleColor
        ...
</TextView>

<TextView
        android:id="@+id/quoteIntro"
        android:textColor=@introColor
        ...
</TextView>

I found a solution which seems to work. First you need to define the custom color fields in attr.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>

<attr name="titleColor" format="reference|color" />
<attr name="introColor" format="reference|color" />

</resources>

Next you define your themes

<style name="AppTheme.MyDark" parent="android:Theme">
   <item name="titleColor">#FFFFFF</item>
   <item name="introColor">#FFFFFF</item>
</style>


<style name="AppTheme.MyLight" parent="android:Theme">
   <item name="titleColor">#000000</item>
   <item name="introColor">#004444</item>
</style>

and finally in your layout

<TextView
    android:id="@+id/quoteTitle"
    android:textColor="?titleColor"
    ...
</TextView>

<TextView
    android:id="@+id/quoteIntro"
    android:textColor="?introColor"
    ...
</TextView>

i found the solution mainly here

There seems to be no explanation in the official android documentation about using attributes. Best resource I found is here
