Class must either be declared abstract or implement abstract method error

Question

This is my code that is suppose to change some text on button press:-

public class MyActivity extends ActionBarActivity {
    TextView txtview;
    Button butto;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_my);
        ImageView imageView = (ImageView) findViewById(R.id.image);
        txtview = (TextView) findViewById(R.id.text);
        butto = (Button) findViewById(R.id.buttn);

        butto.setOnClickListener(new View.OnClickListener() {

                public void Onclick(View paramView) {
                txtview.setText("You Clicked it!");
            }
        });

    }}

The View.OnClickListener is underlined and it gives me the error "Class must either be declared abstract or implement abstract method". This code has been mostly copied from the internet and its suppose to be working fine. Probably its a Android Studio error only. How can I get it to work?

Answer 1

View.OnClickListener must implement the function onClick() otherwise your class should be abstract, so that you could implement your onClick() function in some child class. But in your case you have made a spelling mistake. It should be onClick() instead of Onclick();

Answer 2

You got the method name wrong :

public void Onclick(View paramView)

should be

public void onClick(View paramView)

Following Java naming conventions can help you.
