Kotlin Android start new Activity

Question

I want to start another activity on Android but I get this error:

Please specify constructor invocation; classifier \'Page2\' does not have a companio

Answer 1

You can generally simplify the specification of the parameter BlahActivity::class.java by defining an inline reified generic function.

inline fun  Context.createIntent() =
    Intent(this, T::class.java)

Because that lets you do

startActivity(createIntent()) 

Or even simpler

inline fun  Activity.startActivity() {
    startActivity(createIntent()) 
} 

So it's now

startActivity()
