当包含 textColor 的样式应用于 textView 的 textAppearance 时，文本的颜色没有改变

Question

I want to reduce my xml code repetition. So I made some standard styles for text in textView. We can apply styles under 'style' attribute as well as 'android:textAppearance' attribute in textView.

Below are some styles I made for text appearance-

<style name="Grey">
    <item name="android:textColor"> #333333 </item>
</style>

<style name="CodeFont" parent="@android:style/TextAppearance.Medium">
    <item name="android:textColor"> #00FF00 </item>
    <item name="android:typeface">monospace</item>
    <item name="android:textSize">20sp</item>
</style>

When I apply these styles under 'textAppearance' attribute the color of the text is not changing in none of the above styles. It's working under 'style' attribute of textView.

//textColor not working
<TextView
    android:id="@+id/profile_name"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="Full Name"
    android:textAppearance="@style/CodeFont"/>

//textColor working
<TextView
    android:id="@+id/profile_name"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="Full Name"
    style="@style/CodeFont"/>

I want them to work under 'textAppearance' attribute so that I can apply some other style under 'style' attribute. And according to android documentation we can apply textColor styles under 'textAppearance' attribute.

Please suggest some solution to this. Thanks

Try setting the text color in your widget as null like this:

<TextView
android:id="@+id/profile_name"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Full Name"
android:textColor="@null"  //add this line
android:textAppearance="@style/CodeFont"/>

Also, I think you should try to Invalidate cache and Restart Android Studio. Import and linking issues can be solved like this sometimes.

This snippet works for me

 <style name="fonts" parent="TextAppearance.AppCompat">
    <item name="android:textColor">#245546</item>
    <item name="android:textSize">30dp</item>
</style>

and textview is

  <TextView
    android:id="@+id/sample"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="Welcome to stackoverflow"
    android:textAppearance="@style/fonts"/>

Sometimes if you don't give android:textColor in styles you can have this issue that text color won't appear in your TextView , So the solution is to just give completely <item name="android:textColor">@color/yourColor</item> in styles rather than this <item name="textColor">@color/yourColor</item> .. your problem would be resolved:)
