Code in Beginning Android Games book giving error

I'm a newbie to android development and i was reading the code for creating a custom button which tells u the no of times u clicked tht button. The code is as follows:

package com.helloworld;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class HelloWorldActivity extends Activity implements View.OnClickListener {

    Button button;

开发者_如何学编程    int touchCount;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        button=new Button(this);
        button.setText("Click Me");
        button.setOnClickListener(this);
        setContentView(button);
    }
    public void onCLick(View v)
    {
        touchCount++;
    button.setText("touched me"+touchCount+"time(s)");
    }
}

THE ERROR :

The type HelloWorldActivity must implement the inherited abstract method      View.OnClickListener.onClick(View) - Breakpoint:HelloWorldActivity

I looked in a couple of sites and tried something but nothing worked. Please help me out. Thank you.

It should be onClick, not onCLick (lower case l).

Your HelloWorldActivity is acting as (or implementing) a View.OnClickListener. As an OnClickListener Java is expecting you implement the method "onClick". Java is case sensitive and interprets onClick is different from onCLick (where you have a capital L rather then the expected lower case). Try updating your onClick to a lower l.
