I\'m working on a little program, and I need to add a custom dialog that passes some info to the calling acitivity when it closes. I extended the dialog class, and when I try to

You could have your calling activity implement a custom listener interface that is called when the dialog closes:

public interface MyDialogListener {
    void OnCloseDialog();
}

public class MyActivity implements MyDialogListener {
    public void SomeMethod() {
        MyDialog myDialog = new MyDialog(this, this);
        myDialog.show();
    }

    public void OnCloseDialog() {
        // Do whatever you want to do on close here
    }

}

public class MyDialog extends Dialog {
    MyDialogListener mListener;

    public MyDialog (Context context, MyDialogListener listener) {
        super(context, R.style.Dialog);
        mListener = listener;
    }

    public void onClick(View view) {
        switch (view.getId()) {
            case R.id.CloseButton:
                mListener.OnCloseDialog();
                dismiss()
                break;
            default:
                //...
        }
    }
}

This is especially useful if you want to send stuff back to the caller at any other time besides on dismissal.
