Make ActionBar Title Uppercase

How do I make the ActionBar title uppercase? Some answers suggest putting true but this has no effect when I put it in the actio

Solution 1:

You need to set android:textAllCaps="true" on the text appearance for the action bar's title, rather than the action bar style itself or on your base activity theme.

<style name="AppTheme" parent="AppBaseTheme">
    ...
    <item name="actionBarStyle">@style/Widget.MyApp.ActionBar.Solid</item>
</style>

<style name="Widget.MyApp.ActionBar.Solid"
       parent="Widget.AppCompat.ActionBar.Solid">
    <item name="titleTextStyle">@style/TextAppearance.MyApp.Widget.ActionBar.Title</item>
</style>

<style name="TextAppearance.MyApp.Widget.ActionBar.Title"
       parent="TextAppearance.AppCompat.Widget.ActionBar.Title">
    <item name="android:textAllCaps">true</item>
</style>
