鉴于很多网友发私信或者留言想我所要课程表项目源码，我这里将其开源到我的Github上：

https://github.com/mmc-maodun/Multi-function-curriculum-Based-on-Android

工欲善其事，必先利其器，刚接触Android一个月的时候，便准备做一款Android平台下的多功能课程表，做了一周多，便出去实习了，近几个月一直在忙公司（实习）的事情，利用断断续续的闲暇时间，将该APP做出来了，虽说这东东不算难做，但真要做起来，遇到的问题还是蛮多的，在不断的发现问题与解决问题中成长，也是对自己的一种锻炼。

该APP已经上传到小米应用商店，欢迎下载：http://app.xiaomi.com/detail/42115

【基本功能】
编辑、添加、删除和查看课程表；
【核心功能】
1、打开课表时来，默认显示当天的课程信息；
2、根据用户的设置，在上课前通知提醒；
3、根据用户的设置，上课时自动将手机调节振动，下课后将手机恢复正常铃声；

先附上几张在模拟器上截取的效果图片：

完成这个APP之后，大致总结了几点局部功能的实现方法（不是很全），如下：
1、上课自动静音功能的实现：
通过开关控制是否启动后台的SetQuierService，从而在程序退出后一直在后台运行，
在SetQuierService中，用TimeTask，每隔一分钟从数据库中取出一次数据，
并从系统取得一次当天是星期几，以及当前的时间，
通过二者对比较，确定是否开启振动模式以及恢复原始铃声模式设置。
另外：这里写了一个LauncherReceiver用来监听系统开机事件，当用户开启了SetQuierService，但是因为某种原因关机了，
再次开机后，它会在这种情况下开机自启动SetQuierService。

2、课前提醒功能的实现：
通过开关控制是否每隔一分钟发送一次广播，而该广播会被RemindReceiver接收到，从而每隔一分钟从数据库中取得一次数据，
并从系统中取得一次当天是星期几，以及当前的时间，
通过对二者的比较，确定是否启动提醒用户的RemindActivity
另外，该广播的发送通过AlarmManager来实现，参数里设置的休眠不发送广播，但开机后会继续发送，因此不受关机影响。

3、完全退出应用程序采用的方法：
建立一个继承自Application的类MyApplication，在其中定义一个放置Activity的容器，用单例设计模式取得唯一的MyApplication实例，每建立一个Activity，就将其添加到该MyApplication实例的容器中。

4、第一次打开APP时直接创建数据库表，之后直接调用数据库：
采用单例设计模式创建数据库表，通过SharedPreferences保存一标志位，判断是否是第一次创建数据库表。

    文件，设置课前提醒的BroadcastReceiver类    
      package zyb.org.service;import java.util.Calendar;import java.util.Date;import temp.DataBase;import temp.ShareMethod;import zyb.org.editschedule.RemindActivity;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.content.SharedPreferences;import android.database.Cursor;public class RemindReceiver extends BroadcastReceiver {//定义保存每张表数据的cursor集合Cursor[] cursor = new Cursor[7];//保存时间，temp[day][row][hm]表示第day+1个tab选项卡中的第row+1个行中用户输入的第一个（即课程开始）时间拆分为时和分//hm为0时表示时，1表示分，2时代表时和分的组合，即未拆分前的字符串String[][][] temp = new String[7][12][3];//将temp数组中的字符串转化为相应的正数，这里去掉了时和分的组合int[][][] start_time = new int[7][12][2];private int advance_time;@Overridepublic void onReceive(Context arg0, Intent arg1) {//取得数据库DataBase db = new DataBase(arg0);//取出数据库中每日的数据，保存在cursor数组中for(int i=0;i<7;i++){cursor[i]=db.select(i);}//从数据库取出用户输入的上课的时和分，用来设置课前提醒for(int day=0;day<7;day++){ for(int row=0;row<12;row++){cursor[day].moveToPosition(row);temp[day][row][2] = cursor[day].getString(5); if(!temp[day][row][2].equals("")){ temp[day][row][2] = temp[day][row][2].substring(temp[day][row][2].indexOf(":")+2); temp[day][row][0] = temp[day][row][2].substring(0, temp[day][row][2].indexOf(":")); temp[day][row][1] = temp[day][row][2].substring(temp[day][row][2].indexOf(":")+1); } else{ temp[day][row][0] = temp[day][row][1] = "0"; } for(int hm=0;hm<2;hm++){ start_time[day][row][hm] = Integer.parseInt(temp[day][row][hm]); }}}//从该context中启动提醒的activity，根据SDK文档的说明，需要加上addFlags()一句Intent remind_intent = new Intent(arg0, RemindActivity.class);remind_intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);//获取提前提醒的时间值,如果没有获取到则取默认值30分钟//int advance_time = arg1.getIntExtra("anvance_remindtime", 20);//这里模式一定要设置为MODE_MULTI_PROCESS，否则即使相应的xml文件中数据有更新，RemindReceiver中也不能获取更新后的数据，而是一直获取上次的数据， 除非清空缓存SharedPreferences pre = arg0.getSharedPreferences("time", Context.MODE_MULTI_PROCESS);advance_time = pre.getInt("time_choice", 30);int currentday = ShareMethod.getWeekDay();//System.out.println(advance_time);Calendar c = Calendar.getInstance();//获取当前的时和分int current_hourOfDay = c.get(Calendar.HOUR_OF_DAY);int current_minute = c.get(Calendar.MINUTE);//定义一个标志位，用来排除掉重复的提醒boolean flag = true;//循环判断当天的课前提醒for(int i=0;i<12;i++){if(!(start_time[currentday][i][0]==0 && start_time[currentday][i][1]==0)){//将calendar的时和分设置为提醒时候的时和分c.set(Calendar.HOUR_OF_DAY, start_time[currentday][i][0]);c.set(Calendar.MINUTE, start_time[currentday][i][1]);long remind_time = c.getTimeInMillis()-advance_time*60*1000;Date date=new Date(remind_time);c.setTime(date);//获取设置的提醒的时和分int hourOfDay = c.get(Calendar.HOUR_OF_DAY);int minute = c.get(Calendar.MINUTE);//如果到了设定的提醒时间，就启动提醒的activityif(hourOfDay==current_hourOfDay && minute==current_minute){if(flag){arg0.startActivity(remind_intent);//System.out.println("time remind" + i);flag = false;}}else{flag = true;}}}}}
       
    文件，监听系统开机事件，设置是否开机自启动SetQuietService服务    
      package zyb.org.service;import android.app.AlarmManager;import android.app.PendingIntent;import android.app.Service;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.content.SharedPreferences;public class LauncherReceiver extends BroadcastReceiver {@Overridepublic void onReceive(Context arg0, Intent arg1) {//LauncherReceiver用来监听系统开机事件，如果之前已经设置了启动SetQuietService，即quiet_status为true，//而后来因为某种原因关机了，则开机启动SetQuietServiceSharedPreferences preferences = arg0.getSharedPreferences("switch", Context.MODE_MULTI_PROCESS);Boolean quiet_status = preferences.getBoolean("switch_quiet", false);Boolean remind_status = preferences.getBoolean("switch_remind", false);Intent quiet_intent = new Intent(arg0,SetQuietService.class);Intent remind_intent = new Intent(arg0,RemindReceiver.class);PendingIntent pi_remind = PendingIntent.getBroadcast(arg0, 0, remind_intent, 0);AlarmManager am = (AlarmManager)arg0.getSystemService(Service.ALARM_SERVICE);if(quiet_status){arg0.startService(quiet_intent);}if(remind_status){am.setRepeating(AlarmManager.RTC, System.currentTimeMillis(), 60000, pi_remind);}else{am.cancel(pi_remind);}}}
       
    文件，该Activity对应的是一个悬浮的界面，当到了预设的课前提醒时间时，便启动该Activity    
      package zyb.org.editschedule;import zyb.org.androidschedule.R;import android.app.Activity;import android.app.AlertDialog;import android.app.Service;import android.content.Context;import android.content.DialogInterface;import android.content.SharedPreferences;import android.content.DialogInterface.OnClickListener;import android.os.Bundle;import android.os.Vibrator;public class RemindActivity extends Activity{private Vibrator vibrator;@Overridepublic void onCreate(Bundle savedInstanceState){super.onCreate(savedInstanceState);SharedPreferences pre = getSharedPreferences("time", Context.MODE_MULTI_PROCESS);int advance_time = pre.getInt("time_choice", 30);//获取系统的vibrator服务，并设置手机振动2秒vibrator = (Vibrator)getSystemService(Service.VIBRATOR_SERVICE);vibrator.vibrate(2000);// 创建一个对话框final AlertDialog.Builder builder= new AlertDialog.Builder(RemindActivity.this);builder.setIcon(R.drawable.ic_launcher);builder.setTitle("温馨提示");builder.setMessage("童鞋，还有" + advance_time + "分钟就要上课了哦！");builder.setPositiveButton("确定" ,new OnClickListener(){@Overridepublic void onClick(DialogInterface dialog , int which){// 结束该ActivityRemindActivity.this.finish();}}).show();}@Overridepublic void onBackPressed() {super.onBackPressed();// 结束该ActivityRemindActivity.this.finish();}}
       
    点击“关于作者”和“软件相关”，会分别跳转到文件和文件，这两个文件及其相应的布局文件比较简单，不再附上。    
    
              网友提醒忘了附上list_v2.xml,list_v.xml和edit_shedule.xml三个布局文件，补充一点：list_v.xml是我第一次设定的listview内的每个item内的布局文件，后来改为了list_v2.xml，在项目中并没有引用list_v.xml文件，因此这里只贴出list_v2.xml和edit_shedule.xml两个布局文件，分别如下：                  list_v2.xml文件
      <?xml version="1.0" encoding="UTF-8"?>                                                                       
    
    edit_shedule.xml文件
   <?xml version="1.0" encoding="utf-8"?>
