I&#39;m trying to make this:

and this is what I&#39;m getting:

[![enter image description here][2]][2]

I can&#39;t make the background blur and transparent at the same time, how could I do that?

when I try to do it with &quot;alpha&quot; it removes opacity in the text as well, which does not happen in the original photo.

        android:layout_width=&quot;match_parent&quot;
        android:layout_height=&quot;match_parent&quot;
        
        app:blk_blurRadius=&quot;1&quot;

        app:blk_fps=&quot;1&quot; /&gt;
    &lt;androidx.constraintlayout.widget.ConstraintLayout
        android:layout_width=&quot;match_parent&quot;
        android:layout_height=&quot;match_parent&quot; &gt;



        &lt;TextView
