Question

public class SchedulerSetupReceiver extends WakefulBroadcastReceiver {
    private static final String APP_TAG = "com.hascode.android";

    private static final int EXEC_INTERVAL = 10 * 1000;
    DBhelper dbhelper;

    @Override
    public void onReceive(final Context ctx, Intent intent) {
        Log.d(APP_TAG, "SchedulerSetupReceiver.onReceive() called");
        dbhelper = new DBhelper(ctx);

        String[] ID = dbhelper.FetchAllID();
        String[] time = dbhelper.FetchAlltime();
        ArrayList<PendingIntent> intentArray = new ArrayList<PendingIntent>();

        AlarmManager alarmManager = (AlarmManager) ctx
                .getSystemService(Context.ALARM_SERVICE);

        Calendar calendar = Calendar.getInstance();
        calendar.set(calendar.HOUR_OF_DAY, 16);
        calendar.set(calendar.MINUTE, 22);
        calendar.set(calendar.SECOND, 0);
        calendar.set(calendar.MILLISECOND, 0);
        long sdl = calendar.getTimeInMillis();

        for (int k = 0; k < ID.length; k++) {

            intent = new Intent(ctx, SchedulerEventReceiver.class);
            // Loop counter `i` is used as a `requestCode`
            PendingIntent pendingIntent = PendingIntent.getBroadcast(ctx, k,
                    intent, 0);
            // Single alarms in 1, 2, ..., 10 minutes (in `i` minutes)

            alarmManager.set(AlarmManager.ELAPSED_REALTIME_WAKEUP, sdl,
                    pendingIntent);

            intentArray.add(pendingIntent);

        }

    }

Answer 1

试试这个

  "highlight" : [ 
    {
        "status" : "upcoming",
        "limit":"10"
    }, 
    {
        "status" : "overdue",
        "limit":"1"`
    }, 
    {
        "status" : "today",
        "limit":"3"
    }
]

确保您已在Manifest中注册了广播接收器。

<receiver android:name=".SchedulerEventReceiver"/>

并提供警报许可。

<uses-permission android:name="com.android.alarm.permission.SET_ALARM"/>

Answer 3

我想你忘记告诉日历今天是星期几。

calendar.setTimeInMillis(System.currentTimeMillis());

当我在android中设置时间时，警报未被触发
