基于eclipse开发的简单的音乐播放器

具有简单的音乐播放器基本功能新手练手蛮好。 开发技术主要技术java 同时用到了 sql 的一点点知识 ackage com.ku.shujuku; import android.content.Context; import android.database.sqlite.SQLiteDatabase; import android.database.sqlite.SQLiteDatabase.CursorFactory; import android.database.sqlite.SQLiteOpenHelper; public class DBhelper extends SQLiteOpenHelper { public DBhelper(Context context) { super(context, "stud", null, 1); } @Override public void onCreate(SQLiteDatabase db) { db.execSQL("create table Lg(LgId nvarchar(20) ,LgName nvarchar(20))"); db.execSQL("insert into Lg values('120','120')"); db.execSQL("insert into Lg values('1201','1201')"); } @Override public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { } }
