New feature DataBinding is used in the project
I think it is time to get rid of findByViewId on Android, what 'bout you? We can hence use DataBinding which allows us to bind views in a simple way on Android. This is similar to Butter Knife but I guess, it is way comfortable to use and understand.
As for mentioning simply.
We add dataBinding block in build.gradle
We move our views into tags.
Build your project to let it Android generate required files
We declare ActivityDataBinding class and start binding views easily.
