关于点击事件的问题求助。

package com.suice.button;



import android.app.Activity;

import android.os.Bundle;

import android.view.View;

import android.widget.Button;



public class ButtonActivity extends Activity {

    /** Called when the activity is first created. */

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        

        Button b=(Button) findViewById(R.id.button);

        b.setOnClickListener(new OnClickListener() {

			

			public void onClick(View v) {

				// TODO Auto-generated method stub

				

			}

		});

    }

}

这一行报错：b.setOnClickListener(new OnClickListener() {
内容：
Multiple markers at this line
- The method setOnClickListener(View.OnClickListener) in the type View is not applicable for the arguments (new
OnClickListener(){})
- OnClickListener cannot be resolved to a type

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    android:orientation="vertical" >



    <Button

        android:id="@+id/button"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:text="点我啊" />



</LinearLayout>

求助。
