A button class that prevents code repetition

Issue

I was trying create a Button that makes the user to a new Activity, i create something like that:

//Main Activity
btnChangeScene.setOnClickListener { goToActivity(this, SecondActivity::class.java) }



fun Context.goToActivity(activity: Activity, classs: Class<*>?) {
        val intent = Intent(activity, classs)
        startActivity(intent)
        activity.finish()
    }

But when I try to go back to MainActivity, I need to create a new "goToActivity" inside SecondActivity and that's so bad for any programmer, because for every new activity, I need to create a new "goToActivity" inside it.

How can I get this same function implemented inside this class, so I can just call this function, instead of having to create it every time I create a new activity?

class ButtonActivity(private val button: Button): Activity(){

// code here
}

Solution

create a new kotlin companion object like below.

companion object AnyName {

fun Context.goToActivity(activity: Activity, classs: Class<*>?) {
        val intent = Intent(activity, classs)
        startActivity(intent)
        activity.finish()
    }
    }

now you call this function from any class.
