java - How to access "Activity.this" in Kotlin?

Question

I have this piece of Java code:

MaterialDialog builder = new MaterialDialog.Builder(MainActivity.this)

I want to get the MainActivity object in Kotlin. The automatic conversion breaks at MainActivity.this.

Answer 1

You can get a reference to your MainActivity object in Kotlin by using a qualified this. e.g.:

class MyActivity : MainActivity() {
    val builder = MaterialDialog.Builder(this@MyActivity)
}
