title: android - overdraw layout allows touch through LinearLayout
body: <p>in the following UI I have this below drabable overlaying the entire screen. The LinearLayout is transparent and allows controls below it to be clickable or touchable. Basically I can scroll a list below this LinearLayout as well as click controls. How do I disable that?</p>
  
  <p>See attached example.<img src="https://i.stack.imgur.com/xLeWC.png" alt="enter image description here"></p>
  
  <p>Thank you</p>
