到自己电脑上运行，发现错误，src文件夹下score_activity.java文件错误

package com.donglihan.CollegeLifeManager;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.RatingBar;
import android.widget.Toast;

public class score_activity extends Activity {
    /* (non-Javadoc)
     * @see android.app.Activity#onCreate(android.os.Bundle)
     */
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.score);
        setTitle("评个分吧O(∩_∩)O~");

    RatingBar ratingBar = (RatingBar) findViewById(R.id.rating_bar);
    ratingBar.setOnRatingBarChangeListener(
            new RatingBar.OnRatingBarChangeListener() {  
            @Override  
            public void onRatingChanged(RatingBar ratingBar,  
                    float rating, boolean fromUser) {  
                // TODO Auto-generated method stub  
                ratingBar.setRating(rating);  
                Toast.makeText(score_activity.this,  
                        "谢谢评分！", Toast.LENGTH_SHORT).show();
                finish();
                }         
            }
            );  
    }
}
