Android编程实现PendingIntent控制多个闹钟的方法

public void setClock(){  if(lva.ids.equals("")||lva.ids==null||lva.ids.length()<0){  Toast.makeText(AlarmTest.this, "请选择要设定的闹钟！", Toast.LENGTH_LONG).show();  }  else{  /*到这里了，重点是怎样获取时间和分钟并传入其中*/  r=dao.getAll(lva.ids.replaceAll("[//p{Punct}//p{Space}]+", ""));  Toast.makeText(AlarmTest.this, r.getId()+"时："+r.getHour()+"分："+r.getMinute(), Toast.LENGTH_LONG).show();  c.setTimeInMillis(System.currentTimeMillis());  c.set(Calendar.HOUR_OF_DAY, Integer.parseInt(r.getHour()));  c.set(Calendar.MINUTE, Integer.parseInt(r.getMinute()));  c.set(Calendar.SECOND, 0);  c.set(Calendar.MILLISECOND, 0);  Intent i=new Intent(AlarmTest.this,CallAlarm.class);  PendingIntent sender=PendingIntent.getBroadcast(AlarmTest.this, r.getId(), i, 0);  AlarmManager am=(AlarmManager)getSystemService(Context.ALARM_SERVICE);  am.set(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), sender);}
