I noticed a lot of people ask this question, and I change my code follow this answer: How to set bold title in Action Bar?
However, I can't change title color to red and style to bold. This is my code link in github:
https://github.com/fhlkm/TitleStyle.git
And this is my Style.xml code:
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light">
<item name="android:actionBarStyle">@style/MyTheme.ActionBar</item>
<item name="actionBarStyle">@style/MyTheme.ActionBar</item>
</style>
<style name="MyTheme.ActionBar" parent="Widget.AppCompat.ActionBar.Solid">
<item name="titleTextStyle">@style/MyTheme.ActionBar.TitleTextStyle</item>
</style>
<style name="MyTheme.ActionBar.TitleTextStyle" parent="TextAppearance.AppCompat">
<item name="android:background">#ff0000</item>
<item name="android:textStyle">bold</item>
</style>
I don't know why but after I change from parent="TextAppearance.AppCompat" to parent="Widget.AppCompat.ActionBar.TabText", the color and textStyle is changed, this is the new xml:
<style name="AppTheme" parent="Theme.AppCompat.Light">
<item name="actionBarStyle">@style/ActionBarCompat</item>
</style>
<style name="ActionBarCompat" parent="Widget.AppCompat.ActionBar.Solid">
<item name="titleTextStyle">@style/titleStyle</item>
</style>
<style name="titleStyle" parent="Widget.AppCompat.ActionBar.TabText">
<item name="android:textColor">@android:color/holo_blue_dark</item>
<item name="android:textStyle">bold</item>
</style>
