android access final variable in a public sub

I have a checkbox in android UI interface that need to set confirm. I need to declare it as final as it need to access it inside the inner class. However, I also want a public sub to check the value of the checkbox and also reset it.

The problem is I cannot access the final variable chkConfirm inside public sub.

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    final CheckBox chkConfirm;
    chkConfirm = (CheckBox) findViewById(R.id.chkConfirm);
    chkConfirm.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            if (chkConfirm.isChecked()) {

            } else {

            }
        }
    });
    chkConfirm.setChecked(false);

    }

public Boolean isConfirmed() {
    if (chkConfirm.isChecked() ) {
        chkConfirm.setChecked(false);
        return true;
    } else {
        return false;
    }

}

How to solve?

Move the final CheckBox chkConfirm to the class, as private variable:

private CheckBox chkConfirm;
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);


    chkConfirm = (CheckBox) findViewById(R.id.chkConfirm);
    chkConfirm.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            if (chkConfirm.isChecked()) {

            } else {

            }
        }
    });
    chkConfirm.setChecked(false);

    }

public Boolean isConfirmed() {
    if (chkConfirm.isChecked() ) {
        chkConfirm.setChecked(false);
        return true;
    } else {
        return false;
    }

}
