I have created an ActionBar (android.support.v7.widget.Toolbar
) as below.
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/myToolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize">
</android.support.v7.widget.Toolbar>
In my ActionBar, other than the title, I also have Subtitle. However I would like to customize the Subtitle. In customize, I mean the font size, color and typeface.
I've tried through various Theme and Style, and still unsuccessful.
If there's a simple complete example of how that could be done, that would really help. Thanks!
In method 1 Just go to the activity_main. xml file and add a TextView in the toolbar widget with the font-family attribute. The complete code for the activity_main. xml file is given below.
suggest use android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" instead. To keep using default styles for the customised TextView, try something like style="@style/TextAppearance. AppCompat.
If you don't already have this namespace attribute in your layout file add it:
xmlns:app="http://schemas.android.com/apk/res-auto"
Update your Toolbar attributes in your layout file like this:
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/myToolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:titleTextAppearance="@style/ToolbarTitleAppearance"
app:subtitleTextAppearance="@style/ToolbarSubtitleAppearance"
android:minHeight="?attr/actionBarSize">
</android.support.v7.widget.Toolbar>
Add styles like these:
<style name="ToolbarTitleAppearance" parent="@style/TextAppearance.Widget.AppCompat.Toolbar.Title">
<item name="android:textSize">20dp</item>
<!-- include other attributes you want to change: textColor, textStyle, etc -->
</style>
<style name="ToolbarSubtitleAppearance" parent="@style/TextAppearance.Widget.AppCompat.Toolbar.Subtitle">
<item name="android:textSize">14dp</item>
</style>
Comments on this answer discuss whether the units for textSize
should be dp
or sp
. When I originally wrote this answer, I looked at the Android source files and saw that dp
was used. I recommend staying with that. As FrancescoDonzello explains in his comment, the size of the Toolbar is fixed and, unlike other widgets, will not expand to contain text enlarged by changes to the phone settings.
