Why Is Setting OnClickListener Working Once?

I want to migrate a very solid project structure that I use to Kotlin. I first tried the basics: Activities and Fragment transactions. It appears so easy and simple: class MainActi

Solution 1:

You have to set your variables that are bound by ButterKnife as lateinit var instead of val. Try

@BindView(R.id.btn_sale)
lateinit var title: Button

@BindView(R.id.btn_visit)
lateinit var title: Button

Solution 2:

Answer : solved it by getting rid of KotterKnife and ButterKnife and use android's findViewById. I guess one of the advantages of the language and the framework's progress make some libraries obsolete or unnecessary.
