Create a Circular Button with an Icon in Android Jetpack Compose - Coding

In Android, Buttons are the most basic and frequently used UI element that lets users call a function or start a task from the application context. It is provided to the user to give input to the application with the help of a click. These Buttons are largely customizable and visual attributes can be altered according to the theme of the application.

Create a Circular Button with an Icon in Android Jetpack Compose

In this article, we will show you how you could create a Circular Button with an Icon in Android using Jetpack Compose. Follow the below steps once the IDE is ready.

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. While choosing the template, select Empty Compose Activity. If you do not find this template, try upgrading the Android Studio to the latest version. 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 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 com.horje.circularbutton 
  
import android.os.Bundle 
import android.widget.Toast 
import androidx.activity.ComponentActivity 
import androidx.activity.compose.setContent 
import androidx.compose.foundation.BorderStroke 
import androidx.compose.foundation.layout.* 
import androidx.compose.foundation.shape.CircleShape 
import androidx.compose.material.* 
import androidx.compose.material.icons.Icons 
import androidx.compose.material.icons.filled.Add 
import androidx.compose.runtime.Composable 
import androidx.compose.ui.Alignment 
import androidx.compose.ui.Modifier 
import androidx.compose.ui.graphics.Color 
import androidx.compose.ui.platform.LocalContext 
import androidx.compose.ui.tooling.preview.Preview 
import androidx.compose.ui.unit.dp 
  
class MainActivity : ComponentActivity() { 
    override fun onCreate(savedInstanceState: Bundle?) { 
        super.onCreate(savedInstanceState) 
        setContent { 
            // Calling the composable function  
            // to display element and its contents 
            MainContent() 
        } 
    } 
} 
  
// Creating a composable  
// function to display Top Bar 
@Composable
fun MainContent(){ 
    Scaffold( 
        topBar = {TopAppBar( 
            title = {Text( 
                "GFG | Circular Button", 
                color = Color.White)}, 
            backgroundColor = Color(0xff0f9d58) 
        ) }, 
        content = { MyContent()} 
    ) 
} 
  
// Creating a Composable function to create 
// a Circular Button with an Icon inside it 
// Calling this function as content in the above function 
@Composable
fun MyContent(){ 
    
    // Fetching the local context 
    val mContext = LocalContext.current 
    Column(Modifier.fillMaxSize(), verticalArrangement = Arrangement.Center, horizontalAlignment = Alignment.CenterHorizontally) { 
  
         // Creating an Outlined Button and setting 
        // the shape attribute to CircleShape 
        // When the Button is clicked, a Toast  
        // message would be displayed 
        OutlinedButton(onClick = { Toast.makeText(mContext, "This is a Circular Button with a + Icon", Toast.LENGTH_LONG).show()}, 
            modifier= Modifier.size(100.dp), 
            shape = CircleShape, 
            border= BorderStroke(5.dp, Color(0XFF0F9D58)), 
            contentPadding = PaddingValues(0.dp), 
            colors = ButtonDefaults.outlinedButtonColors(contentColor =  Color.Blue) 
        ) { 
            // Adding an Icon "Add" inside the Button 
            Icon(Icons.Default.Add ,contentDescription = "content description", tint=Color(0XFF0F9D58)) 
        } 
  
    } 
} 
  
// For displaying preview in the  
// Android Studio IDE emulator 
@Preview(showBackground = true) 
@Composable
fun DefaultPreview() { 
    MainContent() 
}

Output:

When you run the application, you can see that a Circular Button appears with an ‘+’ icon inside it.
