Why function call becomes error: invalid method declaration; return type required?

1

Hi there,

Please look at the attached screen shoot. In 3rd version code CheatActivity.java, following code gets error: invalid method declaration; return type required. It’s a function call. Also for the function defintion, it gives even weird error. .

Android1|690x431
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_cheat);
mAnswerIsTrue = getIntent().getBooleanExtra(EXTRA_ANSWER_IS_TRUE, false);
mAnswerTextView = (TextView) findViewById(R.id.answer_text_view);

    mShowAnswerButton = (Button) findViewById(R.id.show_answer_button);
    mShowAnswerButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if (mAnswerIsTrue) {
                mAnswerTextView.setText(R.string.true_button);
            } else {
                mAnswerTextView.setText(R.string.false_button);
            }
        }

        *setAnswerShownResult(true);* Here is the error!
    });

    private void setAnswerShownResult(boolean isAnswerShown){
        Intent data = new Intent();
        data.putExtra(EXTRA_ANSWER_SHOWN, isAnswerShown);
        setResult(RESULT_OK, data);
    }
}

Thanks,

I am not a Java person, but I see a syntax error: setAnswerShownResult is invoked outside a method’s body.

    mShowAnswerButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if (mAnswerIsTrue) {
                mAnswerTextView.setText(R.string.true_button);
            } else {
                mAnswerTextView.setText(R.string.false_button);
            }
        }

        *setAnswerShownResult(true);* Here is the error!
    });

Compare

    mShowAnswerButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if (mAnswerIsTrue) {
                mAnswerTextView.setText(R.string.true_button);
            } else {
                mAnswerTextView.setText(R.string.false_button);
            }
            setAnswerShownResult(true);
        }
    });
