Android 获取图像视图的开关（v.getId（））中的错误

我正在做一个练习，这意味着每次单击图像时，我都需要将图像从imageView更改为按钮imageView。但是我在设置switch case语句时出错

import android.app.Activity;
import android.os.Bundle;
import android.content.pm.ActivityInfo;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ImageView;
import android.widget.Switch;


public class MainActivity extends Activity implements OnClickListener {
     ImageView display;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
    display = (ImageView) findViewById(R.id.imageView);
    ImageView image1 = (ImageView) findViewById(R.id.iVmg1);
    ImageView image2 = (ImageView) findViewById(R.id.iVmg2);
    ImageView image3 = (ImageView) findViewById(R.id.iVmg3);
    ImageView image4 = (ImageView) findViewById(R.id.iVmg4);
    ImageView image5 = (ImageView) findViewById(R.id.iVmg5);
    ImageView image6 = (ImageView) findViewById(R.id.iVmg6);
    ImageView image7 = (ImageView) findViewById(R.id.iVmg7);
    ImageView image8 = (ImageView) findViewById(R.id.iVmg8);
    ImageView image9 = (ImageView) findViewById(R.id.iVmg9);
    ImageView image10 = (ImageView) findViewById(R.id.iVmg10);



    image1.setOnClickListener(this);
    image2.setOnClickListener(this);
    image3.setOnClickListener(this);
    image4.setOnClickListener(this);
    image5.setOnClickListener(this);
    image6.setOnClickListener(this);
    image7.setOnClickListener(this);
    image8.setOnClickListener(this);
    image9.setOnClickListener(this);
    image10.setOnClickListener(this);

}


@Override
public void onClick(View v) {
     Switch(v.getId()) {
            case R.id.iVmg1:
                display.setImageResource(R.drawable.img1);
                break;
            case R.id.iVmg2:
                display.setImageResource(R.drawable.img2);
                break;
            case R.id.iVmg3:
                display.setImageResource(R.drawable.img3);
                break;
            case R.id.iVmg4:
                display.setImageResource(R.drawable.img4);
                break;
            case R.id.iVmg5:
                display.setImageResource(R.drawable.img5);
                break;
            case R.id.iVmg6:
                display.setImageResource(R.drawable.img6);
                break;
            case R.id.iVmg7:
                display.setImageResource(R.drawable.img7);
                break;
            case R.id.iVmg8:
                display.setImageResource(R.drawable.img8);
                break;
            case R.id.iVmg9:
                display.setImageResource(R.drawable.img9);
                break;
            case R.id.iVmg10:
                display.setImageResource(R.drawable.img10);
                break;


    }
}
}

你得到了什么错误？如果只是一个编译错误-你有开关而不是开关。不确定这是打字错误还是notthx开关是合作的ans thx
