如何TextView的文本顏色設置爲特定的主題顏色

Question

我嘗試學習Android的主題，並陷入困境設置TextView TEXTCOLOR到另一種顏色，然後這個全球：

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

我創造了這個：

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

，我想我可以用它在TextView的XML像

android:textColor="?attr/chatBubbleTextColor" 

，但我不能讓我工作也許它不起作用？
我知道我可以這樣做：

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

但我真的需要做這樣嗎？我只是想創建一個顏色屬性不是創建新的風格

這裏是主題，it's兩個主題和chatBubbleTextColor是兩個

Answer 1

我找到了答案，以我自己的問題here

基本上它是這樣的：

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> 

Answer 2

進入你的TextView使用style="@style/chatBubbleTextColor"代替android:textColor="?attr/chatBubbleTextColor"。 像這樣

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

Answer 3

，如果你在，如果你把它設置爲任何TextView顏色android:textColor="?attr/chatBubbleTextColor"那麼如果在AppTheme設置chatBubbleTextColor它將工作應用該主題的活動與你在這個主題<style name="BaseTheme.Bohemia" parent="AppTheme">設置顏色爲chatBubbleTextColor風格也將提供給整個應用
