Android:类型视图的OnClickListener（）方法未定义

我得到一个错误：类型视图的OnClickListener（）方法未定义

我是android开发新手。以下是我的代码：

package com.example.playword;

import java.io.IOException;

import android.app.Activity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.os.Handler;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;

public class PlayWord extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        //final Handler mHandler = new Handler();

        final TextView nicholas = (TextView) findViewById(R.id.nicholas);
        final TextView was = (TextView) findViewById(R.id.was);

        nicholas.setText("Nicholas ");
        was.setText("was ");

        View.OnClickListener handler = View.OnClickListener(){
            public void onClick(View v) {
                switch (v.getId()) {
                    case R.id.nicholas: // doStuff
                        nicholas.setText("Nicholas (Clicked!) ");
                        break;
                    case R.id.was: // doStuff
                        was.setText("was (Clicked!) ");
                        break;
                }
            }
        }

        findViewById(R.id.nicholasBtn).setOnClickListener(handler);
        findViewById(R.id.wasBtn).setOnClickListener(handler);

    }
}

错误将在以下几行中突出显示：

        View.OnClickListener handler = View.OnClickListener(){
            public void onClick(View v) {

非常感谢！：）

您忘记了

new

关键字和分号：

View.OnClickListener handler = new View.OnClickListener(){
    ...
};
