如何将TextView文本颜色设置为特定的主题颜色 [英] How to set TextView text color to specific Theme color

问题描述

我尝试学习Android主题，并遇到了将TextView TextColor设置为另一种颜色然后出现这种全局性的麻烦:

I try to learn Android Themes and got into trouble setting a TextView TextColor to another color then this global:

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

我创建了这个:

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

，以为我可以在TextView xml中使用它

and thought I could use it in the TextView xml like

android:textColor="?attr/chatBubbleTextColor"

但是我无法使其正常工作，也许它不能那样工作?
我知道我可以这样:

but i cannot get it to work maybe it does not work like that?
I know I can do like this:

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

但是我真的必须这样做吗?我只想创建一个color属性，而不创建一种新样式

But do I really have to do like this? I only want to create a color attribute not creating a new style

这里是主题，它是两个主题，而chatBubbleTextColor两者都不同

Here is the Theme, it´s two Themes and the chatBubbleTextColor is different for both

Bohemia应用程序主题和红色应用程序主题

推荐答案

我找到了自己问题的答案

I found the answer to my own question here.

基本上是这样的:

在文件attr.xml中，我对此进行了定义:

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>

接下来，我将添加到我的两个BaseTheme中:

Next I add to my two 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>

最后是我的布局:

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