Rounded Button In Android Studio With Examples

Creating a rounded button in android studio is not so hard. In this android studio tutorial we will learn how to create rounded buttons with different styles. We also create the icon button which can be on the left or right side of the button.

Button In Android Studio

Buttons in android studio are used to perform some task when we tap or press on it. These are the parts of GUI which have the feature of tapping or clicking. They call any function or move to another screen or can do anything which we want to perform. Rounded Buttons are also the same button in android studio, we provide the radius of the corners of the button so it becomes a rounded button.

By default android studio provides a Button widget which we can use but we can not provide rounded corners of it. We have to create a drawable design to make it rounded corners.

Default Button Of Android Studio

In the above screen there is a simple button we can not round its corners. We can change its background color and other properties. This is the default button in android studio.

Create a drawable layout inside the Drawable directory. Copy and paste following code you can change the background color and radius.

rect_rounded_button.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="@color/black"/>
    <stroke android:color="@color/black" android:width="1.5dp"/>
    <corners android:radius="15dp"/>
</shape>

Now use as below in Button attribute.

   android:background="@drawable/rect_rounded_button"

 <Button
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_margin="15dp"
    android:padding="15dp"
    android:background="@drawable/rect_rounded_button"
    android:textSize="16dp"

 button.setOnClickListener(new View.OnClickListener() {
    @Override
