我的闹钟有问题，我不想每天都显示通知，所以我尝试了这些代码：
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 19);
calendar.set(Calendar.MINUTE, 00);
Intent downloader = new Intent(getApplicationContext(), NotificationDemandeReceiver.class);
final PendingIntent recurringDownload = PendingIntent.getBroadcast(this, 0,
downloader, 0);
AlarmManager alarms = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);
alarms.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, recurringDownload);
和
Intent myIntent = new Intent(this , NotificationDemandeService.class);
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
PendingIntent pendingIntent = PendingIntent.getService(this, 0, myIntent, 0);
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 19);
calendar.set(Calendar.MINUTE, 00);
calendar.set(Calendar.SECOND, 00);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 24*60*60*1000 , pendingIntent);
这两个代码的问题是：如果我安排到19:00，如果此时应用程序没有运行，通知将会显示。
如果应用程序在预定时间运行，则会显示通知，但如果我关闭应用程序并再次运行，则会再次显示通知！
所以我这样做了：
// Construct an intent that will execute the AlarmReceiver
Intent nintent = new Intent(getApplicationContext(), NotificationDemandeReceiver.class);
// Create a PendingIntent to be triggered when the alarm goes off
final PendingIntent npIntent = PendingIntent.getBroadcast(this, NotificationDemandeReceiver.REQUEST_CODE,
nintent, PendingIntent.FLAG_UPDATE_CURRENT);
// Setup periodic alarm every 5 seconds
long nfirstMillis = System.currentTimeMillis(); // first run of alarm is immediate
int nintervalMillis = 1000 * 60 * 60 * 24; // 10 minutes
AlarmManager nalarm = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);
nalarm.setRepeating(AlarmManager.RTC_WAKEUP, nfirstMillis, nintervalMillis, npIntent);
Alarme属于一个函数public void scheduleAlarm（）{}我在Splashscreen上调用它：
Thread logoTimer = new Thread() {
public void run() {
try {
int logoTimer = 0;
while (logoTimer < 10000) {
sleep(100);
logoTimer = logoTimer + 1000;
};
List<Demande> demandesRenvoie = db.getAllDemandesRenvoie();
if (!(demandesRenvoie.isEmpty())) {
scheduleAlarm();
}
startActivity(new Intent("android.intent.action.ACCUEIL"));
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
finish();
}
}
};
那么如何每天安排一个警报，并且没有＆＃34;重启＆＃34;关闭运行应用程序后？
Splashscreen（我开始2个服务，一个用于ksoapservice（每10分钟一次），另一个用于通知（每天））：
public class Splashscreen extends Activity {
DatabaseHandler db = new DatabaseHandler(this);
//Initialisation de l activite avec les donnees necessaires
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splashscreen);
Thread logoTimer = new Thread() {
public void run() {
try {
int logoTimer = 0;
while (logoTimer < 10000) {
sleep(100);
logoTimer = logoTimer + 1000;
};
List<Demande> demandesRenvoie = db.getAllDemandesRenvoie();
if (!(demandesRenvoie.isEmpty())) {
scheduleAlarm();
}
startActivity(new Intent("android.intent.action.ACCUEIL"));
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
finish();
}
}
};
logoTimer.start();
}
public void scheduleAlarm() {
// Construct an intent that will execute the AlarmReceiver
Intent intent = new Intent(getApplicationContext(), EnvoieReceiver.class);
// Create a PendingIntent to be triggered when the alarm goes off
final PendingIntent pIntent = PendingIntent.getBroadcast(this, EnvoieReceiver.REQUEST_CODE,
intent, PendingIntent.FLAG_UPDATE_CURRENT);
// Setup periodic alarm every 5 seconds
long firstMillis = System.currentTimeMillis(); // first run of alarm is immediate
int intervalMillis = 1000 * 60 * 10; // 10 minutes
AlarmManager alarm = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);
alarm.setInexactRepeating(AlarmManager.RTC_WAKEUP, firstMillis, intervalMillis, pIntent);
// Construct an intent that will execute the AlarmReceiver
Intent nintent = new Intent(getApplicationContext(), NotificationDemandeReceiver.class);
// Create a PendingIntent to be triggered when the alarm goes off
final PendingIntent npIntent = PendingIntent.getBroadcast(this, NotificationDemandeReceiver.REQUEST_CODE,
nintent, PendingIntent.FLAG_UPDATE_CURRENT);
// Setup periodic alarm every 5 seconds
long nfirstMillis = System.currentTimeMillis(); // first run of alarm is immediate
int nintervalMillis = 1000 * 60 * 60 * 24; // 10 minutes
AlarmManager nalarm = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);
nalarm.setInexactRepeating(AlarmManager.RTC_WAKEUP, nfirstMillis, nintervalMillis, npIntent);
/*

// Triggered by the Alarm periodically (starts the service to run task)
@Override
public void onReceive(Context context, Intent intent) {
Intent i = new Intent(context, NotificationDemandeService.class);

答案 0 :(得分：-1)
您是否将此intent-filter添加到接收器？
<receiver android:name=".your.Receiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
还需要许可
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
