14.findViewById的过去及未来

We have lots of alternatives for this, and you may wonder why do we need another solution. Let’s compare the different solutions based on these criteria: null-safety, compile-time safety, and speed.

Column 1	ButterKnife	Kotlin Synthetics	Data Binding	findViewById	View Binding
Fast	❌ *	✅	❌ *	✅	✅
Null-safe	❌	❌	✅	❌	✅
Compile-time safe	❌	❌	✅	✅ **	✅

* ButterKnife and Data Binding solutions are slower because they use an annotation-based approach ** findViewById() is compile-time safe since API 26 because we don’t need to cast the type of view anymore.
