How to center align of LinearLayout in Android?

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.

If the orientation of LinearLayout is horizontal, then the center aligned LinearLayout would look as shown in the following screenshot.
