Android LinearLayout – Arrange Children Vertically
To arrange items of LinearLayout vertically, assign android:orientation attribute of this LinearLayout with the value “vertical”.
android:orientation="vertical"
Let us create an Android application with LinearLayout containing two Button widgets as children. We shall arrange these children vertically.
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: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.

Conclusion
In this Kotlin Android Tutorial, we learned how to arrange children of LinearLayout vertically.
