Android - Layout Rounded Corners

 Lets see how to apply rounded corners to layouts in Android.

1. Create an Android project with an empty activity.

2. Create a drawable named rounded_corner_drawable.xml inside drawable resources folder.

3. Add following code into created file.

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#FF4F79"/>
    <corners android:radius="35dp"/>
</shape>

4. Open activity layout XML file.

5. Add following layouts into layout file.

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".RoomsActivity">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_margin="20dp"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        android:background="@drawable/rounded_corner_drawable"/>

</androidx.constraintlayout.widget.ConstraintLayout>

6. Result :

We used background property of our layout to apply rounded corner background.

Use radius value in created drawable to change corner radius size.
