I need to change the font size, the font itself, and center the text in the ToolBar. I took a template from Bottom Navigation Activity studio.
I was trying setting the text size in themes.xml (I was able to change the background color and text color there)
<style name="CustomToolBarStyle" parent="TextAppearance.Widget.AppCompat.Toolbar.Title">
<item name="titleTextColor">@color/black</item>
<item name="android:background">@color/white</item>
I was trying to use this option in themes.xml:
<item name="android:gravity">center</item>
It didnt help. I tried to follow this instruction: https: //stackoverflow.com/questions/26533510/android-toolbar-center-title-and-custom-font Throws android.support.v7.widget.Toolbar into an error and get a crash.
For API level 21+ you can use app:titleTextAppearance
property of toolbar
<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/yourstyle" />
and override the default title size in a custom style:
<style name="yourstyle" parent="TextAppearance.Widget.AppCompat.Toolbar.Title">
<item name="android:textSize">18sp</item>
<item name="android:fontFamily">yourFont</item>
</style>
For centering, you should follow this answer and if this and none of the other answer works for you from the same post https://stackoverflow.com/a/38175403/9917400 , than just use a linear layout inside Toolbar.
You can set constraint-layout inside the toolbar
<androidx.appcompat.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?actionBarSize"
app:layout_collapseMode="pin">
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
android:textColor="@color/blue"
android:textSize="16sp"
app:fontPath="fonts/xxx" />
</androidx.constraintlayout.widget.ConstraintLayout>
</androidx.appcompat.widget.Toolbar>
If you're using androidx
don't use android.support.v7.widget.Toolbar
.
You have to use androidx.appcompat.widget.Toolbar
.
Create toolbar.xml
in res/layout. Put this code:
<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context=".MainActivity">
<com.google.android.material.appbar.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<androidx.appcompat.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="yourToolBarBackgroundColor"
>
<TextView
android:id="@+id/toolbar_title"
style="@style/TextAppearance.AppCompat.Widget.ActionBar.Title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="TestToolBar"
android:fontFamily="yourFont"
android:textSize="yourSizeOfText"
android:textColor="yourTextColor" />
</androidx.appcompat.widget.Toolbar>
</com.google.android.material.appbar.AppBarLayout>
<include layout="@layout/activity_main" />
</androidx.coordinatorlayout.widget.CoordinatorLayout>
Disable ActionBar in themes.xml:
<style name="Theme.YourProject" parent="Theme.MaterialComponents.DayNight.NoActionBar">
For night theme you have to do same thing in themes.xml(night)
Then in MainActivity.java in onCreate:
setContentView(R.layout.toolbar);
