1.发广播（我这种）
//时间一到，发送广播（闹钟响了）
//广播接受者中（跳转Activity）
// 跳转Activity，在这个Activity中播放音乐（前面博文有介绍播放音乐，在这就没写）
2. 直接跳Activities
3. 跳Service服务
//（二）设置闹钟(周期)
public void setAlarmCycle(View view){

//获取当前系统的时间
Calendar calendar=Calendar.getInstance();
int hour=calendar.get(Calendar.HOUR_OF_DAY);
int minute=calendar.get(Calendar.MINUTE);

//弹出时间对话框

c.set(Calendar.MINUTE,i1);

Intent intent=new Intent();
intent.setAction("com.lsj.administrator.myapplicatio.swj");

//将来时态的跳转  ang eng ing ong
pendingIntent = PendingIntent.getBroadcast(SwjActivity.this,0x101,intent,0);
//设置周期闹钟
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,c.getTimeInMillis(),5000, pendingIntent);

//时间一到，发送广播（闹钟响了）
//广播接受者中（跳转Activity）
// 跳转Activity，在这个Activity中播放音乐

}
},hour,minute,true);

timePickerDialog.show();
}
//（三）取消周期
public void cancelCycle(View view){

}
//（四）发送通知（系统）
public void sendNotification(View view){
//实例化通知管理器

//（五）发送自定义通知（仿今日头条）

//设置对应IMAGEVIEW的ID的资源图片

.setWhen(System.currentTimeMillis())// 通知产生的时间，会在通知信息里显示
.setTicker("有新资讯")
.setAutoCancel(true)
.setPriority(Notification.PRIORITY_DEFAULT)// 设置该通知优先级
.setOngoing(false)//不是正在进行的   true为正在进行  效果和.flag一样
.setSmallIcon(R.drawable.icon);

Notification notify = mBuilder.build();
notify.contentView = view_custom;
mNotificationManager.notify(notifyId, notify);
}

public PendingIntent getDefalutIntent(int flags){
