title: A semi transparent overlay with a button and a label?
body: <p>I'm trying to achieve something similar to the attached image - simply a semi-transparent overlay and a label and a button. I have tried adding a view with a button and a label and decreasing the alpha but I can't get it to work. Does anyone know how I could achieve something similar while trying to be cheap on memory. </p>
