AlarmService

 public void setAlarm() {
    alarmManager = (AlarmManager) getActivity().getSystemService(ALARM_SERVICE);

    alarmIntent = new Intent(getActivity(), AlarmReceiver.class);
    pendingIntent = PendingIntent.getBroadcast(getActivity(), 0, alarmIntent, 0);

    Calendar calendar = Calendar.getInstance();

    calendar.setTimeInMillis(System.currentTimeMillis());
    calendar.set(Calendar.HOUR_OF_DAY, 17);
    calendar.set(Calendar.MINUTE, 15);
    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
    //alarmManager.setRepeating(AlarmManager.RTC, AlarmManager.INTERVAL_HALF_DAY, AlarmManager.INTERVAL_HALF_DAY, pendingIntent);

}

MyAlarmSevice

public class AlarmReceiver extends BroadcastReceiver {

NotificationManager notificationManager;

@Override
public void onReceive(Context context, Intent intent) {
    Intent service1 = new Intent(context, MyAlarmService.class);
    context.startService(service1);
}

对于每日行情，我做了一些事情......

public void setAlarm() {
    // Quote in Morning at 08:32:00 AM
        Calendar calendar = Calendar.getInstance();

        calendar.set(Calendar.HOUR_OF_DAY, 8);
        calendar.set(Calendar.MINUTE, 32);
        calendar.set(Calendar.SECOND, 0);
        calendar.set(Calendar.MILLISECOND, 0);

        Calendar cur = Calendar.getInstance();

        if (cur.after(calendar)) {
            calendar.add(Calendar.DATE, 1);
        }

        Intent myIntent = new Intent(context, DailyReceiver.class);
        int ALARM1_ID = 10000;
        PendingIntent pendingIntent = PendingIntent.getBroadcast(
                context, ALARM1_ID, myIntent, PendingIntent.FLAG_UPDATE_CURRENT);
        AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);

}

并获得此reciver

public class DailyReceiver extends BroadcastReceiver {
DatabaseHelper databaseHelper;

@Override
public void onReceive(Context context, Intent intent) {

    String quote ;

    long when = System.currentTimeMillis();
    NotificationManager notificationManager = (NotificationManager) context
            .getSystemService(Context.NOTIFICATION_SERVICE);

    Intent notificationIntent = new Intent(context, DailySpecialActivity.class);
    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,
            notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    Uri alarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

    // get your quote here
    quote = doSomeMethod();


    NotificationCompat.Builder mNotifyBuilder = new NotificationCompat.Builder(
            context).setSmallIcon(R.mipmap.ic_launcher)
            .setContentTitle("My Quotes")
            .setContentText(quote).setSound(alarmSound)
            .setAutoCancel(true).setWhen(when)
            .setLargeIcon(BitmapFactory.decodeResource(context.getResources(), R.mipmap.ic_launcher))
            .setStyle(new NotificationCompat.BigTextStyle().bigText(quote))
            .setContentIntent(pendingIntent)
            .setVibrate(new long[]{1000, 1000, 1000, 1000, 1000});  // Declair VIBRATOR Permission in AndroidManifest.xml
    notificationManager.notify(5, mNotifyBuilder.build());
  }

}

在您重新启动手机时，您还需要重新启动闹钟，所以我已经

了

public class WakeUpAlarmReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {

    if (intent.getAction().equals("android.intent.action.BOOT_COMPLETED")) {

        // Quote in Morning

        Calendar calendar = Calendar.getInstance();

        calendar.set(Calendar.HOUR_OF_DAY, 8);
        calendar.set(Calendar.MINUTE, 30);
        calendar.set(Calendar.SECOND, 0);
        calendar.set(Calendar.MILLISECOND, 0);

        Calendar cur = Calendar.getInstance();

        if (cur.after(calendar)) {
            calendar.add(Calendar.DATE, 1);
        }

        Intent myIntent = new Intent(context, DailyReceiver.class);
        int ALARM1_ID = 10000;
        PendingIntent pendingIntent = PendingIntent.getBroadcast(
                context, ALARM1_ID, myIntent, PendingIntent.FLAG_UPDATE_CURRENT);
        AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);

      }
   }
}

最后这是你的AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.nils.myquotesapp">
<!--you must need this three permissions-->
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
<uses-permission android:name="android.permission.VIBRATE" />


<application
    android:name="com.nils.myquotesapp.QuotesApplication"
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:largeHeap="true"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">

    <activity
        android:name="com.nils.myquotesapp.Activity.MainActivity"
        android:label="@string/app_name"
        android:screenOrientation="portrait"
        android:theme="@style/AppTheme.NoActionBar">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <receiver
        android:name="com.nils.myquotesapp.DailyReceiver"
        android:enabled="true" />

    <receiver
        android:name="com.nils.myquotesapp.WakeUpAlarmReceiver"
        android:enabled="true">
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
            <category android:name="android.intent.category.DEFAULT" />
            <action android:name="android.intent.action.QUICKBOOT_POWERON" />
        </intent-filter>
    </receiver>

</application>
<meta-data
    android:name="com.google.android.gms.version"
    android:value="@integer/google_play_services_version" />
</manifest>

至于最好的运气兄弟...... !!

您可以执行这些日常任务，例如警报管理器和其他具有以下服务的任务。

以下可能更有用，更节省电池并优化使用。

1：JobSchedular

2：ScheduledExecutorService

虽然它是由android支持库提供的，但您可以在互联网上找到非常有用的示例。
