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);
}
