package com.example;

import android.app.Activity;
import android.os.Bundle;
import android.widget.ImageButton;
import android.widget.Toast;
import android.view.View;
import android.view.MotionEvent;
import android.media.MediaPlayer;

单从代码的角度来看，你可以尝试改进一下，代码很冗余

了解一下，lz说得很对，在Android中用户界面始终是第一位的，其次才是数据库设计，实现，程序页面的跳转,细节完善等，不知你这个程序是怎么个用法，[e-mail]
