Last Updated : 30 Jan, 2022

A Button in Android is a UI element provided to a user to click to perform a certain action. A text can be set inside the button to name it. However, this text can be seen in a particular font only which is set by default.

So in this article, we will show you how you could change the Button text font in Android. Follow the below steps once the IDE is ready.

Step by Step Implementation

Step 1: Create a New Project in Android Studio

To create a new project in Android Studio please refer to How to Create/Start a New Project in Android Studio. We demonstrated the application in Kotlin, so make sure you select Kotlin as the primary language while creating a New Project.

Step 2: Working with the activity_main.xml file

Navigate to the app > res > layout > activity_main.xml and add the below code to that file. Below is the code for the activity_main.xml file. Add a Button in this file.

XML

<?xml version="1.0" encoding="utf-8"?> <RelativeLayout      xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:app="http://schemas.android.com/apk/res-auto"     xmlns:tools="http://schemas.android.com/tools"     android:layout_width="match_parent"     android:layout_height="match_parent"     tools:context=".MainActivity">      <Button         android:id="@+id/button_1"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_centerInParent="true"         android:text="CLick to change font"/>  </RelativeLayout>

Step 3: Working with the MainActivity.kt file

Go to the MainActivity.kt file and refer to the following code. Below is the code for the MainActivity.kt file. Comments are added inside the code to understand the code in more detail.

Kotlin

package org.geeksforgeeks.changebuttonfont  import android.graphics.Typeface import androidx.appcompat.app.AppCompatActivity import android.os.Bundle import android.widget.Button  class MainActivity : AppCompatActivity() {     override fun onCreate(savedInstanceState: Bundle?) {         super.onCreate(savedInstanceState)         setContentView(R.layout.activity_main)          // Declaring and initializing         // Button from the layout file         val mButton = findViewById<Button>(R.id.button_1)          // Declaring integer variable         // to use in when loop         var clicks = 0          // When button is clicked         mButton.setOnClickListener {             // Variable is incremented             clicks += 1             // Enters when loop and changes typeface             when(clicks){                 1-> {mButton.setTypeface(Typeface.MONOSPACE)                     mButton.text = "Monospace"}                  2-> {mButton.setTypeface(Typeface.SANS_SERIF)                     mButton.text = "Sans Serif"}                  3-> {mButton.setTypeface(Typeface.DEFAULT_BOLD)                     mButton.text = "Default Bold"}                  4-> {mButton.setTypeface(Typeface.SERIF)                     mButton.text = "Serif"}                  5-> {mButton.setTypeface(Typeface.DEFAULT)                     mButton.text = "Default"                     // Returns back to the top (Monospace)                     clicks = 0}             }         }     } }
