How to set bold title in Action Bar?

Question

I am editing the style xml trying to get the Activity title bold.

<style name="MyTheme" parent="@android:style/Theme.Holo.Light">
    <item name="android:actionBarStyle">@style/MyActionBar</item>
</style>

<style name="MyActionBar" parent="@android:style/Widget.Holo.Light.ActionBar">
    <item name="android:background">#81CFEB</item>
    <item name="android:textStyle">bold</item>
</style>

But only what I can set is the background color desired. I do not why the textStyle is not set to bold.

Anyone know how to solve it?

Solution 1

Can you please try with this:

<?xml version="1.0" encoding="utf-8"?>
<resources>
  <style name="MyTheme" parent="@android:style/Theme.Holo.Light">
    <item name="android:actionBarStyle">@style/MyTheme.MyActionBar</item>
  </style>

  <style name="MyTheme.MyActionBar"parent="@android:style/Widget.Holo.Light.ActionBar">
    <item name="android:titleTextStyle">@style/MyTheme.MyActionBar.TitleTextStyle</item>
  </style>

  <style name="MyTheme.MyActionBar.TitleTextStyle" parent="@android:style/TextAppearance.Holo.Widget.ActionBar.Title">
    <item name="android:background">#81CFEB</item>
    <item name="android:textStyle">bold</item>
  </style>
</resources>

Solution 2

For those using AppCompat, you'll need something like this:

<style name="MyTheme" parent="Theme.AppCompat">
    <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">#81CFEB</item>
    <item name="android:textStyle">bold</item>
</style>

Seems the first item in MyTheme.ActionBar is not needed.

I think it might be for back compat @kbitzerCZ?

I have tried to leave it out for both 6.0.1 (API 23) and 4.0.3 (API 15) and it works (hope I'm not missing something).

hmm ok, with things like primaryColor you sometimes need to double up like that. i've removed it based on your tests though
