Answer 1

Put this property on the LinearLayout tag or element:

android:background="@color/fui_transparent"

Answer 2

I used

android:elevation="0sp"

to remove the shadow. Works fine and you can still have a background set on the LinearLayout.

Answer 3

If you use Dialog class, try this answer: https://stackoverflow.com/a/3114466/837714 Quote from there:

Create a custom style and place it in your values folder

<?xml version="1.0" encoding="utf-8"?>
<resources>
  <style name="YourCustomStyle" parent="android:Theme">
    <item name="android:backgroundDimEnabled">false</item>
  </style>
</resources> 

To set a style to an individual dialog you can use

Dialog dialog = new Dialog(context, R.style.YourCustomStyle);

UPDATE

Move up from comments:

I misunderstood the question. Actual solution is:

dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);
