Pass this object into event handler

Question

I got the code below how do I pass the current object "this" into the event handler so that I can pass it to the object Foo:

btn.setOnClickListener(new View.OnClickListener(this) {
public void onClick(View view) {
   new Foo(this).AlertBox("Hello Lennie!");
}
});

Where "this" is: android.app.Activity

i get an error that it can't find the constructor:

Answer 1

new Foo(android.app.Activity.this).AlertBox(...)
