我在应用中有几个主题,它可以正常工作。现在,当用户选择BaseTheme.Red
时,我想将聊天气泡文字颜色设置为红色,当用户选择BaseTheme.Orange
时,我想将文字颜色设置为橙色(参见下面的代码)
这只是聊天气泡文字右边我想要红色为'红色'和橙色为橙色主题和应用程序中的所有其他TextView文字颜色将具有默认主题颜色
我尝试学习Android主题并且在将此聊天TextView文本颜色设置为另一种颜色然后这个全局时遇到了麻烦:
<item name="android:textColor">@color/white</item>
我创建了这个:在BaseTheme.Red
<item name="chatBubbleTextColor">@color/material_red_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?
我如何使用下面的主题让这个工作?
以下是两个主题Red
和Orange

答案 0 :(得分:1)
我找到了自己问题的答案here
基本上,它是这样的:
在文件attr.xml中,我定义了这个:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<attr name="ChatBubbleBackGroundColor" format="reference|color" />
<attr name="ChatBubbleTextColor" format="reference|color" />
</resources>
接下来我添加到我的两个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>
最后在我的布局中
<TextView
android:id="@+id/quoteTitle"
android:textColor="?ChatBubbleTextColor"
android:BackGround="?ChatBubbleBackGroundColor"
...
</TextView>
