Use Component

In Xml Layout

<com.qmdeve.blurview.widget.ProgressiveBlurViewGroup
    android:id="@+id/progressiveContainer"
    android:layout_width="match_parent"
    android:layout_height="240dp"
    app:progressiveDirection="topToBottom"
    app:progressiveOverlayColor="#AAFFFFFF"
    app:progressiveBlurRadius="25dp">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:text="Progressive Blur Group" />

</com.qmdeve.blurview.widget.ProgressiveBlurViewGroup>

In Java

ProgressiveBlurViewGroup group = new ProgressiveBlurViewGroup(context);
group.setGradientDirection(ProgressiveBlurViewGroup.DIRECTION_TOP_TO_BOTTOM);
group.setBlurRadius(25f);
group.setOverlayColor(0xAAFFFFFF);

In Kotlin

val group = ProgressiveBlurViewGroup(context)
group.setGradientDirection(ProgressiveBlurViewGroup.DIRECTION_TOP_TO_BOTTOM)
group.setBlurRadius(25f)
group.setOverlayColor(0xAAFFFFFF.toInt())
