How to make the corners of a button round?

Create a xml file in drawable folder like below

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" android:padding="10dp">
    <!-- you can use any color you want I used here gray color-->
    <solid android:color="#ABABAB"/> 
    <corners android:radius="10dp"/>
</shape>

Apply this as background to button you want make corners round.

Or you can use separate radius for every corner like below

android:bottomRightRadius="10dp"
android:bottomLeftRadius="10dp"
android:topLeftRadius="10dp"
android:topRightRadius="10dp"

If you want something like this

Button preview

here is the code.

1.Create a xml file in your drawable folder like mybutton.xml and paste the following markup:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:state_pressed="true" >
        <shape android:shape="rectangle"  >
            <corners android:radius="3dip" />
            <stroke android:width="1dip" android:color="#5e7974" />
            <gradient android:angle="-90" android:startColor="#345953" android:endColor="#689a92"  />            
        </shape>
    </item>
    <item android:state_focused="true">
        <shape android:shape="rectangle"  >
            <corners android:radius="3dip" />
            <stroke android:width="1dip" android:color="#5e7974" />
            <solid android:color="#58857e"/>       
        </shape>
    </item>  
    <item >
       <shape android:shape="rectangle"  >
            <corners android:radius="3dip" />
            <stroke android:width="1dip" android:color="#5e7974" />
            <gradient android:angle="-90" android:startColor="#8dbab3" android:endColor="#58857e" />            
       </shape>
    </item>
</selector>

2.Now use this drawable for the background of your view. If the view is button then something like this:

<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:padding="10dp"
    android:textColor="#ffffff"
    android:background="@drawable/mybutton"
    android:text="Buttons" />

Is there an easy way to achieve this in Android?

With Jetpack Compose you can use the shape parameter:

    Button( 
        onClick = { /* Do something! */ },
        shape = RoundedCornerShape(8.dp)
    ){
        Text("Button")
    }

With the Material Components library you can use the MaterialButton with the app:cornerRadius attribute.

Something like:

    <com.google.android.material.button.MaterialButton
        android:text="BUTTON"
        app:cornerRadius="8dp"
        ../>

enter image description here

It is enough to obtain a Button with rounded corners.

You can use one of Material button styles. For example:

<com.google.android.material.button.MaterialButton
    style="@style/Widget.MaterialComponents.Button.OutlinedButton"
    .../>

enter image description here

Also starting from the version 1.1.0 you can also change the shape of your button. Just use the shapeAppearanceOverlay attribute in the button style:

  <style name="MyButtonStyle" parent="Widget.MaterialComponents.Button">
    <item name="shapeAppearanceOverlay">@style/ShapeAppearanceOverlay.MyApp.Button.Rounded</item>
  </style>

  <style name="ShapeAppearanceOverlay.MyApp.Button.Rounded" parent="">
    <item name="cornerFamily">rounded</item>
    <item name="cornerSize">16dp</item>
  </style>

Then just use:

<com.google.android.material.button.MaterialButton
   style="@style/MyButtonStyle"
   .../>

You can also apply the shapeAppearanceOverlay in the xml layout:

<com.google.android.material.button.MaterialButton
   app:shapeAppearanceOverlay="@style/ShapeAppearanceOverlay.MyApp.Button.Rounded"
   .../>

The shapeAppearance allows also to have different shape and dimension for each corner:

<style name="ShapeAppearanceOverlay.MyApp.Button.Rounded" parent="">
    <item name="cornerFamily">rounded</item>
    <item name="cornerFamilyTopRight">cut</item>
    <item name="cornerFamilyBottomRight">cut</item>
    <item name="cornerSizeTopLeft">32dp</item>
    <item name="cornerSizeBottomLeft">32dp</item>
</style>
