AlarmManager setInexactRepeating，setWindow，setRepe

要求： -
我需要火在每周的指定日期并从报警将开始日期（比如我想在6:45 PM火上周五，每周周六警报从2017年5月26日开始）报警

问题：-
广播接收器的onReceive()方法不执行时AlarmManager setInexactRepeating ， setWindow或setRepeating方法是从一个循环中调用。

用于此任务的代码是下面提到： -
AndroidManifest.xml中

Answer 1:

试试这个代码的工作周五报警，同样可以为周六首先设置你必须注册您的报警接收器和报警时间

public static void SetAlarmForFriday(Context mContext) {
        try {

            Calendar calendar = Calendar.getInstance();
            calendar.set(Calendar.DAY_OF_WEEK, Calendar.FRIDAY);
            System.out.println("Date " + calendar.getTime());

            int year = calendar.get(Calendar.YEAR);
            int month = calendar.get(Calendar.MONTH) + 1;
            int day = calendar.get(Calendar.DAY_OF_MONTH);

            String DateToConvert = day + "," + month + "," + year + " 10:10 AM";
            Date date = new SimpleDateFormat("dd,MM,yyyy hh:mm a", Locale.ENGLISH).parse(DateToConvert);

            Intent intent = new Intent(mContext, AlarmReceiver.class);
            intent.setAction("setYourActionHere");
            PendingIntent pendingIntent = PendingIntent.getBroadcast(mContext.getApplicationContext(), 234324243, intent, 0);
            AlarmManager alarmManager = (AlarmManager) mContext.getSystemService(mContext.ALARM_SERVICE);

            alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, date.getTime(), AlarmManager.INTERVAL_DAY, pendingIntent);

        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }

使接收机类

public class AlarmReceiver extends BroadcastReceiver {
    public AlarmReceiver() {
    }

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO: This method is called when the BroadcastReceiver is receiving
        // an Intent broadcast.


    }

}

注册您的广播接收器下应用标签清单文件

<receiver
            android:name=".AlarmReceiver"
            android:enabled="true"
            android:exported="true"></receiver>
