How to add a blurry effect on drawable image through XML in android

Question

How can I add a blur effect on a drawable image placed in the image view object of a layout, using xml not Java? I want to code this blur effect in XML.

Answer 1

It is not currently possible to produce a blur effect within the layout XML of an Android application.

However, it is possible through the use of Java. There are a number of techniques available to do this (see here for a recent guide on how to do this effectively). Usually either Renderscript or the re-scaling of the image is used to generate a blur of the image.

Edit:

It may now be possible to achieve a blur solely by adding an XML property through the use of a custom data binding adapter. Check out the data binding library for more on how to create an adapter
