推荐答案

要安排本地通知你需要知道一些这是用来调度像

To schedule local notification you need to know some of the things which are used to schedule the notification like

BroadcastReceivers IntentFilters AlarmManager NotificationService PendingIntent

BroadcastReceivers IntentFilters AlarmManager NotificationService PendingIntent

在MainActivity做以下

In MainActivity do the following

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);

        Intent notificationIntent = new Intent("android.media.action.DISPLAY_NOTIFICATION");
        notificationIntent.addCategory("android.intent.category.DEFAULT");

        PendingIntent broadcast = PendingIntent.getBroadcast(this, 100, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);

        Calendar cal = Calendar.getInstance();
        cal.add(Calendar.SECOND, 15);
        alarmManager.setExact(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), broadcast);
    }

以上code将在15秒后设定闹钟。 15秒后，它会播放notificationIntent。

The above code will schedule an alarm after 15 seconds. After 15 seconds it will broadcast the notificationIntent.

在Intent构造函数中指定的操作在AndroidManifest.xml中定义

The action specified in the Intent constructor is defined in the AndroidManifest.xml
