In Xml Layout

<com.qmdeve.blurview.widget.BlurView
    android:id="@+id/blurView"
    android:layout_width="match_parent"
    android:layout_height="100dp"
    app:blurRadius="25dp"
    app:overlayColor="#AAFFFFFF"
    app:cornerRadius="16dp"
    app:topLeftCornerRadius="24dp"
    app:topRightCornerRadius="24dp"
    app:bottomLeftCornerRadius="8dp"
    app:bottomRightCornerRadius="8dp"
    app:downsampleFactor="2.5" />

In Java

BlurView blurView = new BlurView(context, null);
blurView.setBlurRadius(25f);
blurView.setOverlayColor(0xAAFFFFFF);
blurView.setCornerRadius(16f);
blurView.setTopLeftCornerRadius(24f);
blurView.setDownsampleFactor(2.5f);

In Kotlin

val blurView = BlurView(context, null)
blurView.setBlurRadius(25f)
blurView.setOverlayColor(0xAAFFFFFF.toInt())
blurView.setCornerRadius(16f)
blurView.setTopLeftCornerRadius(24f)
blurView.setDownsampleFactor(2.5f)
