The method setOnClickListener(View.OnClickListener) in the type View is not applicable

import android.app.Activity;
import android.os.Bundle;
import android.widget.Button;
import android.content.DialogInterface;
import android.content.DialogInterface.OnClickListener;
import android.content.Intent;
import android.view.View;



public class Activity_01Activity extends Activity {

    /** Called when the activity is first created. */
    private Button myButton = null;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        myButton=(Button)findViewById(R.id.MyButton);
        myButton.setText("second activity");
        myButton.setOnClickListener(new MyButtonListener());

    }

/*

   class MyButtonListener implements OnClickListener{
        @Override
             public void onClick(DialogInterface dialog, int which) {         //把鼠标移动到MyButtonListener上时，提示，点击添加，默认创建一个函数就是这个
                // TODO Auto-generated method stub
                Intent intent=new Intent();
                intent.setClass(Activity_01Activity.this,otheractivity.class);
                Activity_01Activity.this.startActivity(intent);
                }
        }

*/

    class MyButtonListener implements android.view.View.OnClickListener{
        @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Intent intent=new Intent();
                intent.setClass(Activity_01Activity.this,otheractivity.class);
                Activity_01Activity.this.startActivity(intent);
                }
        }

}

/* */注释部分替换掉后边一个class MyButtonListener implements android.view.View.OnClickListener{} 时,

出现下面错误， myButton.setOnClickListener(new MyButtonListener());

句子中setOnClickListener被红线显示，鼠标移动到上边时，提示下面信息：

The method setOnClickListener(View.OnClickListener) in the type View is not applicable for the arguments (Activity_01Activity.MyButtonListener)

若如上所写，注释掉错误表述，运行无错误。

ps刚入门，看别人的没看到自己想要的回答，自己来一下，哈哈
