Android TableLayout in Kotlin

Android TableLayout is a ViewGroup subclass which is used to display the child View elements in rows and columns. It will arrange all the children elements into rows and columns and does not display any border lines in between rows, columns or cells.

The working of TableLayout is almost similar to HTML table and it contains as many columns as row with the most cells.

How to declare TableLayout and TableRow?

The TableLayout can be defined using <TableLayout> like below:

XML

<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginTop="10dp"
    android:paddingLeft="5dp"
    android:paddingRight="5dp">

    // Add Table rows here
</TableLayout>

and TableRow can be defined using

XML

<TableRow android:background="#51B435" android:padding="10dp">
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="Rank" />
</TableRow>

activity_main.xml file

In this file, we declare the TableLayout and start adding table rows with the help of TableRow. We are creating ranking table of players where we define four columns Rank, Name, Country and Points.

The code for the Table is:

XML

<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginTop="10dp"
    android:paddingLeft="5dp"
    android:paddingRight="5dp">

    <TextView
        android:id="@+id/txt"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="ICC Ranking of Players:"
        android:textSize = "20dp"
        android:textStyle="bold">

    </TextView>


    <TableRow android:background="#51B435" android:padding="10dp">
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="Rank" />
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="Player" />
        <TextView

MainActivity.kt

When we have created layout, we need to load the XML layout resource from our activity onCreate() callback method and access the UI element form the XML using findViewById.

Kotlin

package com.geeksforgeeks.myfirstKotlinapp

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)
        // finding the UI elements


    }
}

TableLayout Output:

We need to run using Android Virtual Device(AVD) to see the output.
