Android - center the text in Toolbar title

To center the text in the Toolbar title in Android, you can use a custom layout for the Toolbar. Here's how you can achieve this:

1. Create a Custom Layout for Toolbar Title

Create a new XML layout file (toolbar_title_centered.xml) in your res/layout directory:

<!-- toolbar_title_centered.xml --> <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/toolbar_title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:text="@string/app_name" android:textSize="20sp" android:textColor="@android:color/white" android:textStyle="bold"/>

In this layout:

  • layout_gravity="center" ensures that the TextView is centered horizontally within the Toolbar.
  • You can customize other attributes such as text size, color, and style based on your app's design requirements.

2. Use the Custom Layout in your Activity or Fragment

In your Activity or Fragment, inflate the custom layout and set it as the Toolbar's title:

import androidx.appcompat.app.AppCompatActivity; import androidx.appcompat.widget.Toolbar; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import android.widget.TextView; public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Toolbar toolbar = findViewById(R.id.toolbar); setSupportActionBar(toolbar); // Inflate custom layout LayoutInflater inflater = LayoutInflater.from(this); View customView = inflater.inflate(R.layout.toolbar_title_centered, null); // Set custom view in toolbar toolbar.addView(customView); getSupportActionBar().setDisplayShowTitleEnabled(false); // Hide default title } }

3. Customize Toolbar in XML Layout

In your activity layout (activity_main.xml or similar), define the Toolbar:

<!-- activity_main.xml --> <androidx.coordinatorlayout.widget.CoordinatorLayout 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="match_parent"> <com.google.android.material.appbar.AppBarLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:theme="@style/AppTheme.AppBarOverlay"> <androidx.appcompat.widget.Toolbar android:id="@+id/toolbar" android:layout_width="match_parent" android:layout_height="?attr/actionBarSize" app:popupTheme="@style/AppTheme.PopupOverlay" /> </com.google.android.material.appbar.AppBarLayout> <!-- Your main content layout --> </androidx.coordinatorlayout.widget.CoordinatorLayout>

Notes:

  • Customization: You can further customize the TextView (toolbar_title_centered.xml) to fit your app's design, such as changing text size, color, or adding additional views.

  • Compatibility: This approach is compatible with both AppCompatActivity and the AndroidX libraries.

  • Title Updates: If you need to update the title programmatically, find the TextView by its ID (R.id.toolbar_title) and set the text accordingly.

This method allows you to center the text in the Toolbar title while retaining the flexibility to customize the appearance and behavior as needed for your Android application.
