java – 找不到符号类onClickListener

任何人都可以帮我这个,我一直在寻找解决方案.

这是代码：

package com.example.veeresh.myapplication;
//import statements
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Button;
import android.view.View;
import android.widget.TextView;

public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Button button1 = (Button)findViewById(R.id.button1);

        button1.setOnClickListener(
                //error: cannot find symbol class onClickListener
                new Button.onClickListener()
                {
                    public void onClick(View v)
                    {
                        TextView text1 = (TextView)findViewById(R.id.text1);
                        text1.setText("Veeresh Here");
                    }
                }
                );
    }
}

错误：

Error:(24,27) error: cannot find symbol class onClickListener
