How to make the corners of a button round?

Question

I want to make the corners of a button round. Is there an easy way to achieve this in Android?

Answer 1

drawable folder

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="#FFFFFF"/>
    <corners android:radius="30dp"/>
    <stroke android:width="2dp" android:color="#999999"/>
</shape>

layout folder

<Button
    android:id="@+id/button2"
    <!-- add style to avoid square background -->
    style="@style/Widget.AppCompat.Button.Borderless"
    android:background="@drawable/corner_button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    />

make sure add style to avoid square background
