Java: calling outer class method in anonymous inner class

Question

Recently, I ran into a mysterious problem in an android project, which I described here. I somehow solved the problem, but still don\'t know the exact reason behind it.

Answer 1

The latter is more explicit and will allow you to call the outer class method if one exists in the inner class with the same name.

class OuterClass {
    void foo() { System.out.println("Outer foo"); }

    View.OnClickListener mListener1 = new View.OnClickListener() {
        void foo() { System.out.println("Inner foo"); }

        @Override public void onClick(View view) {
            foo(); //Calls inner foo
            OuterClass.this.foo(); //Calls outer foo
        }
    }

    View.OnClickListener mListener2 = new View.OnClickListener() {
        @Override public void onClick(View view) {
            foo(); //Calls outer foo
            OuterClass.this.foo(); //Calls outer foo
        }
    }
}
