Android编程，括号错误

Question

  

可能重复：
  Android programming, a little issue.

这次我在括号下得到红色波浪线，告诉我“插入”EnumBody“完成EnumDeclaration”

自上次以来，我重新格式化了我的编码，以便让你们更轻松，抱歉。

这是发生在这段代码的最后一行，在最后一个括号上;

if (position == 3){ 
        Intent intent = new Intent(Main.this, Progress.class); 
        Main.this.startActivity(intent);

这是我的整个活动代码;

package com.example.gymbuddy;

import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.ArrayAdapter;
import android.widget.Spinner;

public class Main extends Activity {

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

    findViewById(R.id.button2).setOnClickListener(new handleButton2());
    findViewById(R.id.button3).setOnClickListener(new handleButton3());
    findViewById(R.id.button4).setOnClickListener(new handleButton4());

    Spinner spinner = (Spinner) findViewById(R.id.spinner);
    ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
            this, R.array.work_array, android.R.layout.simple_spinner_item);
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinner.setAdapter(adapter);
    }

class handleButton2 implements OnClickListener {
    public void onClick(View v) {
        Intent intent = new Intent(Main.this, Benchmark.class);
        startActivity(intent);
        }
    }

class handleButton3 implements OnClickListener {
    public void onClick(View v) {
        Intent intent = new Intent(Main.this, Progress.class);
        startActivity(intent);
        }
    }

class handleButton4 implements OnClickListener {
    public void onClick(View v) {
        Intent intent = new Intent(Main.this, Settings.class);
        startActivity(intent);
        }
    }@

spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
    public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
        if (position == 1){
            Intent intent = new Intent(Main.this, Upperbody.class);
            Main.this.startActivity(intent);
            }
        if (position == 2){
            Intent intent = new Intent(Main.this, Settings.class);
            Main.this.startActivity(intent);
            }
        if (position == 3){
            Intent intent = new Intent(Main.this, Progress.class);
            Main.this.startActivity(intent);
            }
        }
    }
);
}
