Android的使用AlarmManager简单实现定时任务

使用AlarmManager简单实现定时每天或重复执行任务，有3种方式

1）AlarmManager+Service 实现方式

2）AlarmManager+InterService 实现方式

3）AlarmManger + BoardcastReceiver 实现方式

需要在AndroidMainifast.xml 增加权限

1）增加ALARM（闹钟）权限

    <uses-permission android:name="android.permission.SET_ALARM"/><uses-permission android:name="android.permission.WAKE_LOCK"/><uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

2）增加Service和BoardcastReceiver注册

  <service android:name=".service.AlarmService" /><service android:name=".service.AlarmIntentService"/><receiver android:name=".broadcast.AlarmBroadcastReceiver" />

3）Service和BoardcastReceiver定义

 3.1）AlarmService

public class AlarmService extends Service {private final String TAG = "AlarmService";@Overridepublic int onStartCommand(Intent intent, int flags, int startId) {// 在这里执行你的任务Log.e(TAG,"调用闹钟，调用时间："+ DateHelper.timestampToDate(System.currentTimeMillis()) );// 任务执行完毕后，停止Service
        stopSelf();return START_NOT_STICKY;}@Overridepublic IBinder onBind(Intent intent) {return null;}
}

3.2）AlarmIntentService

public class AlarmIntentService extends IntentService
{private final String TAG = "AlarmIntentService";public AlarmIntentService(){super("AlarmIntentService");}@Overrideprotected void onHandleIntent(Intent intent){Log.e(TAG,"调用闹钟，调用时间："+ DateHelper.timestampToDate(System.currentTimeMillis()) );}
}

3.3）AlarmBoardcastReceiver

public class AlarmBroadcastReceiver extends BroadcastReceiver
{private final String TAG = "AlarmBroadcastReceiver";public static String alarmboradcastAction = "alarm.broadcast.upload";@Overridepublic void onReceive(Context context, Intent intent){if(intent.getAction().equals(alarmboradcastAction)){Log.e(TAG,"调用闹钟，调用时间："+ DateHelper.timestampToDate(System.currentTimeMillis()));}}
}

4）AlarmManager结合Service、IntentService、boardcastReceiver使用

4.1）AlarmManager+Service 使用

  /*** AlarmManager + Service 实现定时任务* */public void AlarmServiceTest(){// 设置定时任务的代码片段Intent alarmIntent = new Intent(this, AlarmService.class);PendingIntent pendingIntent = PendingIntent.getService(this, 0, alarmIntent, 0);AlarmManager alarmManager = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);// 设置单次闹钟或重复闹钟// 设置为单次闹钟long triggerAtMillis = System.currentTimeMillis() + 1000; // 10秒后触发alarmManager.set(AlarmManager.RTC_WAKEUP, triggerAtMillis, pendingIntent);// 或者设置重复闹钟（最小时间间隔：1 min）//long intervalMillis = 1000 * 60*1; // 每隔60秒触发一次//alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), intervalMillis, pendingIntent);}

4.2）AlarmManager+IntentService 使用

 /*** AlarmManager + IntentService 实现定时任务* */public void AlarmInterServiceTest(){// 设置定时任务的代码片段Intent alarmIntent = new Intent(this, AlarmIntentService.class);PendingIntent pendingIntent = PendingIntent.getService(this, 0, alarmIntent, 0);AlarmManager alarmManager = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);// 设置单次闹钟或重复闹钟// 设置为单次闹钟//long triggerAtMillis = System.currentTimeMillis() + 1000; // 10秒后触发//alarmManager.set(AlarmManager.RTC_WAKEUP, triggerAtMillis, pendingIntent);// 或者设置重复闹钟（最小时间间隔：1 min）long intervalMillis = 1000 * 60*1; // 每隔60秒触发一次
        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), intervalMillis, pendingIntent);}

4.3）AlarmManager+BroadcastReceiver 使用

  /*** AlarmManager+BroadcastReceiver 方式实现定时任务* */public void AlarmBroadcastTest(){// 设置定时任务的代码片段Intent alarmIntent = new Intent(this, AlarmBroadcastReceiver.class);alarmIntent.setAction(AlarmBroadcastReceiver.alarmboradcastAction);PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, alarmIntent, 0);AlarmManager alarmManager = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);// 设置单次闹钟或重复闹钟// 设置为单次闹钟//long triggerAtMillis = System.currentTimeMillis() + 1000; // 10秒后触发//alarmManager.set(AlarmManager.RTC_WAKEUP, triggerAtMillis, pendingIntent);// 或者设置重复闹钟long intervalMillis = 1000 * 60*1; // 每隔60秒触发一次1000 * 60
        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), intervalMillis, pendingIntent);}

5）AlarmManager定时的调用

@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);AlarmBroadcastTest();AlarmServiceTest();AlarmInterServiceTest();}

6）执行调用效果

E/AlarmBroadcastReceiver: 调用闹钟，调用时间：2025-01-15 15:48:37
E/AlarmService: 调用闹钟，调用时间：2025-01-15 15:48:37
E/AlarmIntentService: 调用闹钟，调用时间：2025-01-15 15:48:37
E/AlarmBroadcastReceiver: 调用闹钟，调用时间：2025-01-15 15:49:32
E/AlarmIntentService: 调用闹钟，调用时间：2025-01-15 15:49:32
E/AlarmBroadcastReceiver: 调用闹钟，调用时间：2025-01-15 15:50:32
