Question

Let’s say we have some Foo class that contains

public void setOnSomethingListener(OnSomethingListener listener);

We register it with:

Foo foo = new Foo();
foo.setOnSomethingListener(new OnSomethingListener(){
  public void onSomething(String data) {
    // ...
  }
});

Is it possible to access from onSomething method parental object that has registered mentioned listener without accessing defined foo value ?

I ask about it because I would like to assign this listener to some parameter and register it in the few objects.

Answer 1

Yes.

What you are doing here is defining an anonymous inner class. You can access attributes and methods of the containing class by doing.

MyContainingClass.this.attributeName
