How to make the corners of a button round?

If you want something like this

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" />

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"

Is there an easy way to achieve this in Android?

Yes, today there is, and it is very simple.
Just use the MaterialButton in the Material Components library with the app:cornerRadius attribute.

Something like:

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

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"    .../>

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>

With Jetpack Compose 1.0.x you can use the shape parameter:

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