Answer 1

This might be a very late reply but I hope it helps someone.

1. You can use third party libs such as RenderScript/Blurry/etc.
2. If you do not want to use any third party libs, you can do the below using alpha(setting alpha to 0 means complete blur and 1 means same as existing).

Note(If you are using point 2) : While setting alpha to the background, it will blur the whole layout. To avoid this, create a new xml containing drawable and set alpha here to 0.5 (or value of your wish) and use this drawable name (name of file) as the background.

For example, use it as below (say file name is bgndblur.xml):

Use the below in your layout :

<....
 android:background="@drawable/bgndblur">

Hope this helped.
