如何将 TextView 文本颜色设置为特定的主题颜色

Question

我尝试学习 Android 主题，但在将 TextView TextColor 设置为另一种颜色时遇到了麻烦，然后是这个全局颜色：

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

我创建了这个：

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

并认为我可以在 TextView xml 中使用它，例如

android:textColor="?attr/chatBubbleTextColor"

但我无法让它工作，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？我只想创建一个颜色属性而不是创建一个新样式

这是主题，它是两个主题，chatBubbleTextColor 两者不同

Answer 1

在您的 TextView 中使用 style="@style/chatBubbleTextColor" 而不是 android:textColor="?attr/chatBubbleTextColor"。像这样

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

Answer 2

如果您将此主题应用于任何 activity，则您已在该主题中为 chatBubbleTextColor 设置颜色 <style name="BaseTheme.Bohemia" parent="AppTheme"> 如果您将其设置为任何 TextView 颜色android:textColor="?attr/chatBubbleTextColor" 如果在 AppTheme 样式中设置 chatBubbleTextColor 它将工作，它将对整个应用程序可用

Answer 3

我找到了我自己的问题的答案 here。

基本上是这样的：

在文件attr.xml中我这样定义：

<?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 BaseThemes:

<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>
