The method makeText(Context, CharSequence, int) in the type Toast is not applicable for the arguments (new View.OnClickListener(){}, String, int)

package comxunfang.button;

import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;

public class MainActivity extends ActionBarActivity {
    private Button bt;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        bt = (Button) findViewById(R.id.btn);

        //第一种
        bt.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                Toast.makeText(this, "这是第1种写法",0).show();
            }
        });
    }

如果这样写的话，就会报Multiple markers at this line
    - Line breakpoint:MainActivity [line: 22] - onClick(View)
    - The method makeText(Context, CharSequence, int) in the type Toast is not applicable for the arguments (new View.OnClickListener(){},
     String, int)

这样的错，如果把Toast.makeText(this, "这是第1种写法",0).show();改成Toast.makeText(MainActivity.this, "我弹出来了", 0).show() ;则是正常的

这说明上下文的对象导致这样的结果
