The official documentation can be found here.

Android Studio – Android studio Kotlin OnClickListerner function

When I implemented the member in the class for the on click listener as shown below:

class QuizQuestionsActivity : AppCompatActivity(), View.OnClickListener {

I was given the option of implementing it as:

 override fun onClick(p0: View?) {

I need it to be

override fun onClick(v: View?) {

can someone explain the difference and why I am not getting the option of v: View

    Both of those functions are the same, it’s just a different name for the View variable. Kotlin parameters are listed with the parameter name first, then the class name.

    If you want p0 to be v instead, just change the parameter name to be v.

    Kotlin provide default parameter with alphabets and digits you can simply change it with your variable name like —

    override fun onClick(v: View?) { }

override fun onClick(view: View?) { } 

override fun onClick(myView: View?) { }

    It’s quit good and it’s meaningful variable name that remember as long time. where P0 and P1 named variable is not like good to remember.

    Hope You can understand what I mean to say.
