No need to cast the result of findViewById?

by

Starting with API 26, findViewById uses inference for its return type, so you no longer have to cast.

Old definition: 

View findViewById(int id)

New definition:

<T extends View> T findViewById(int id)

So if your compileSdk is at least 26, it means that you can make use of this 🙂
