Android LinearLayout – Center Align

To center align LinearLayout, assign android:gravity attribute of this LinearLayout with the value “center”.

android:gravity="center"

Let us create an Android application with LinearLayout containing two Button widgets as children. We shall center align these children using gravity attribute.

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:orientation="vertical">

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="10sp"
        android:text="Reset" />

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="10sp"
        android:text="Submit" />
</LinearLayout>

MainActivity.kt

package com.example.myapplication

import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
    }
}

Run this application and you would get the output as shown in the following screenshot.
