AlarmManager通知每天上午9點的服務和廣播

Question

這是方法來設置每日鬧鐘5時15分

我打電話setAlarm()方法，當我的應用程序啓動第一time.App在那個時候自動打開Notification產生(First Launch time)不斷射擊同樣的通知再次n和interval time約2 min。

注意：生成通知不是問題。

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); 

} 

AlarmService

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); 
} 
} 

MyAlarmSevice

public class MyAlarmService extends Service { 
private static final int NOTIFICATION_ID = 1; 
private NotificationManager notificationManager; 
private PendingIntent pendingIntent; 
private ArrayList<RandomQuotes> randomQuotesArrayList; 
private PrefManager prefManager; 

@Override 
public IBinder onBind(Intent arg0) { 
    return null; 
} 

@SuppressWarnings("static-access") 
@Override 
public void onStart(Intent intent, int startId) { 
    super.onStart(intent, startId); 
    Context context = this.getApplicationContext(); 
    prefManager = new PrefManager(this); 
    randomQuotesArrayList = prefManager.getSharedPreferenceStringList(this, "quote"); 
    notificationManager = (NotificationManager) context.getSystemService(NOTIFICATION_SERVICE); 
    Intent mIntent = new Intent(this, MainActivity.class); 
    pendingIntent = PendingIntent.getActivity(context, 0, mIntent, PendingIntent.FLAG_CANCEL_CURRENT); 
    NotificationCompat.Builder builder = new NotificationCompat.Builder(this); 
    builder.setVibrate(new long[]{5, 5, 5, 5, 5}); 

    builder.setLights(Color.RED, 3, 3); 
    builder.setContentTitle("Quote Of the Day"); 
    builder.setContentText(randomQuotesArrayList.get(0).getRandomQuote() + "\n\n" + "-" + randomQuotesArrayList.get(0).getRandomQuoteAuthor()); 
    String longText; 
    if (!randomQuotesArrayList.get(0).getRandomQuoteAuthor().isEmpty()) { 
     longText = randomQuotesArrayList.get(0).getRandomQuote() + "\n\n" + " -" + randomQuotesArrayList.get(0).getRandomQuoteAuthor(); 
    } else { 
     longText = randomQuotesArrayList.get(0).getRandomQuote() + "\n" +randomQuotesArrayList.get(0).getRandomQuoteAuthor(); 
    } 
    builder.setStyle(new NotificationCompat.BigTextStyle().bigText(longText)); 
    builder.setSmallIcon(R.drawable.qt); 
    builder.setContentIntent(pendingIntent); 
    builder.setDefaults(Notification.DEFAULT_SOUND) 
      .setDefaults(Notification.DEFAULT_ALL).setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)); 
    ; 
    notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE); 
    notificationManager.notify(NOTIFICATION_ID, builder.build()); 
} 
}

日常行情，我有做一些事情....

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); 

} 

，並獲得該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()); 
    } 

} 

在這裏，當你重新啓動手機，您還需要重新啓動報警，所以我必須做

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); 

     } 
    } 
} 

最後這裏是你的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>
