How to set TextView text color to specific Theme c

Question

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>

I created this:

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

and thought I could use it in the TextView xml like

android:textColor="?attr/chatBubbleTextColor"

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>

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

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

Bohemia App Theme and Red App Theme

Answer 1

You have set color for chatBubbleTextColor in this theme <style name="BaseTheme.Bohemia" parent="AppTheme"> if you apply this theme to any activity with in that if you set it to any TextView color android:textColor="?attr/chatBubbleTextColor" then it will work if set chatBubbleTextColor in AppTheme Style it will be available to entire app

Answer 2

Into your TextView use style="@style/chatBubbleTextColor" instead of android:textColor="?attr/chatBubbleTextColor". Something like this

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

Answer 3

I found the answer to my own question here

Basically it goes like this:

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>
