How to change the toolbar text size?
You can add a TextView
to your toolbar and customize as you want:
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent">
<TextView
android:id="@+id/toolbar_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/app_name"
android:textSize="25sp"/>
</android.support.v7.widget.Toolbar>
Use app:titleTextAppearance
:
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="?actionBarSize"
android:id="@+id/toolbar"
app:titleTextAppearance="@style/Toolbar.TitleText" />
and override the default title size in a custom style:
<style name="Toolbar.TitleText" parent="TextAppearance.Widget.AppCompat.Toolbar.Title">
<item name="android:textSize">18sp</item>
</style>
Result:
for example this your toolbar
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:gravity="center"
android:minHeight="?attr/actionBarSize"
app:theme="@style/ThemeOverlay.AppCompat.ActionBar" />
you can simple add this view this
app:titleTextAppearance="@style/yourstyle"
style.xml
<style name="yourstyle" parent="@style/Base.TextAppearance.AppCompat.Title">
<item name="android:textSize">20sp</item>
</style>
like that...
