Android - How to align icon to the right and text to the left in the App Bar?

To align an icon to the right and text to the left in the App Bar (Toolbar) in Android, you can use a combination of a Toolbar and a RelativeLayout or LinearLayout. Here's a step-by-step guide:

Step 1: Define Your Layout

Create a layout XML file for your Toolbar. Here's an example using a RelativeLayout:

<androidx.appcompat.widget.Toolbar android:id="@+id/toolbar" android:layout_width="match_parent" android:layout_height="?attr/actionBarSize" android:background="?attr/colorPrimary" app:title="Your Title" app:titleTextColor="@android:color/white"> <RelativeLayout android:layout_width="match_parent" android:layout_height="match_parent"> <TextView android:id="@+id/toolbar_title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentStart="true" android:text="Your Title" android:textColor="@android:color/white" android:textSize="20sp" /> <ImageView android:id="@+id/toolbar_icon" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentEnd="true" android:layout_centerVertical="true" android:src="@drawable/your_icon" /> <!-- Replace with your icon --> </RelativeLayout> </androidx.appcompat.widget.Toolbar> 

Step 2: Set Up Your Activity

In your activity, set the Toolbar as the support action bar:

import android.os.Bundle import androidx.appcompat.app.AppCompatActivity import androidx.appcompat.widget.Toolbar class MainActivity : AppCompatActivity() { override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) val toolbar: Toolbar = findViewById(R.id.toolbar) setSupportActionBar(toolbar) // Optional: If you want to remove the default title supportActionBar?.setDisplayShowTitleEnabled(false) } } 

Explanation

1. Toolbar: The Toolbar serves as the action bar. Set its background color and title using attributes.

2. RelativeLayout: Used to position the TextView and ImageView relative to each other.

   • The TextView is aligned to the start (left) of the Toolbar.
   • The ImageView is aligned to the end (right) of the Toolbar.

3. Icon: Replace @drawable/your_icon with your actual icon resource.

Alternative: Using LinearLayout

If you prefer a LinearLayout, here's how you can do it:

<androidx.appcompat.widget.Toolbar android:id="@+id/toolbar" android:layout_width="match_parent" android:layout_height="?attr/actionBarSize" android:background="?attr/colorPrimary"> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="horizontal" android:gravity="center_vertical"> <TextView android:id="@+id/toolbar_title" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" android:text="Your Title" android:textColor="@android:color/white" android:textSize="20sp" /> <ImageView android:id="@+id/toolbar_icon" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/your_icon" /> </LinearLayout> </androidx.appcompat.widget.Toolbar> 

Summary

• Use RelativeLayout or LinearLayout inside a Toolbar to align text and icon.
• Set the Toolbar in your activity to manage the app bar.
• Customize the title and icon as needed.

This setup will help you achieve the desired layout in your app's toolbar.
