Ch 04: creating custom controls error!

Hello co-readers of the book!

Currently I am in Chapter 4 of the book.

I have created an xml file 'clearable_edit_text.xml' and 'ClearableEditText.java'
On the TodoList.java, I added this code in onCreate() method

Code:

package com.paad.todolist;
import android.app.Activity;
import android.os.Bundle;
public class TodoList extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.clearable_edit_text);
    }
}

this displays a EditText with Button on its side, The problem is, when I typed something and clicked the clear button, nothing happens...Have I done anything wrong? I copied the code from the book for clearable_edit_text.xml and ClearableEditText.java extends LinearLayout. However the book does not say how to use the custom widgets..Please give me some enlightenment...

Thank you!
