如何将TextView文本颜色设置为特定的主题颜色

标签: android android-theme textcolor

我尝试学习Android主题并且在将TextView TextColor设置为另一种颜色时遇到了麻烦,然后是全局:

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

我创造了这个:

 <item name="chatBubbleTextColor">@color/material_bohemia_500</item>

并认为我可以在TextView xml中使用它,如

android:textColor="?attr/chatBubbleTextColor"

但我不能让它工作也许它不能那样工作?
我知道我可以这样做:

<style name="BohemiachatBubbleTextColor" parent="android:Theme">
    <item name="android:textColor">@color/material_bohemia_500</item>
</style>

但我真的必须这样做吗?我只想创建一个不创建新样式的颜色属性

这是主题,它是两个主题,chatBubbleTextColor对于两个

都不同

我找到了自己问题的答案here

基本上它是这样的:

In the file attr.xml I define this:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <attr name="ChatBubbleBackGroundColor" format="reference|color" />
    <attr name="ChatBubbleTextColor" format="reference|color" />
</resources>

Next I add to my two BaseTheme:

<style name="BaseTheme.Red" parent="AppTheme">
   <item name="ChatBubbleBackGroundColor">@color/material_red_a200</item>
   <item name="ChatBubbleTextColor">@color/material_red_a700</item>
</style>

<style name="BaseTheme.Orange" parent="AppTheme">
   <item name="ChatBubbleBackGroundColor">@color/material_orange_a200</item>
   <item name="ChatBubbleTextColor">@color/material_orange_a700</item>
</style>

and finally in my layout

<TextView
    android:id="@+id/quoteTitle"
    android:textColor="?ChatBubbleTextColor"
    android:BackGround="?ChatBubbleBackGroundColor"
    ...
</TextView>

使用style="@style/chatBubbleTextColor"而不是android:textColor="?attr/chatBubbleTextColor"进入TextView。 像这样的东西

<TextView
                style="@style/chatBubbleTextColor"
                android:id="@+id/my_id"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                 />

如果您将此主题应用于其中的任何活动,如果您将其设置为任何chatBubbleTextColor颜色<style name="BaseTheme.Bohemia" parent="AppTheme">,则您已在此主题TextView中为android:textColor="?attr/chatBubbleTextColor"设置了颜色如果在chatBubbleTextColor样式中设置AppTheme,它将适用于整个应用
