我試圖在每天早上 5 點設(shè)置一個觸發(fā)器，以使手機為 USER_PRESENT 廣播做好準備，但是一旦服務啟動，觸發(fā)器就會關(guān)閉。服務 (PAService) 通過使用stopService和startService打開主活動來關(guān)閉和打開。此代碼在模擬器中運行良好，但不適用于實際的 Android 手機。public class PAService extends Service {static boolean is_ready_to_speak = false;PendingIntent pendingIntent;public PAService() {}public class ScreenReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { if(is_ready_to_speak) { PASpeak paspeak = new PASpeak(); paspeak.sayit(getApplicationContext(),"You're using your phone for the first time this morning"); is_ready_to_speak = false; } }}public static class AlarmReceiver extends BroadcastReceiver { public AlarmReceiver() { Log.d("AlarmReceiver func called","alarm receiver func called"); } @Override public void onReceive(Context context, Intent intent) { Log.d("RECEIVED BROADCAST", "Sometype of ALARM Broadcast received"); PASpeak paspeak = new PASpeak(); paspeak.sayit(context.getApplicationContext(),"ALARM ALARM ALARM"); is_ready_to_speak = true; }}

manager.setRepeating(AlarmManager.RTC_WAKEUP,
calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, // for repeating
// in every 24
// hours
pendingIntent);
的2nd parameter，觸發(fā)時間觸發(fā)報警器立即如果calendar.getTimeInMillis()是在過去。所以發(fā)生的事情是你可能在晚上 7 點打開應用程序。您希望鬧鐘在第二天早上 5 點響起，但您calendar.getTimeInMillis()會在同一天早上 5 點響起 。所以你需要為此添加一個檢查：
Calendar calendar = Calendar.getInstance();
// calendar.setTimeInMillis(System.currentTimeMillis()); // YOU DON'T NEED THIS LINE
calendar.set(Calendar.HOUR_OF_DAY, 5);
calendar.set(Calendar.MINUTE, 0);
calendar.set(Calendar.SECOND, 0);
Calendar current = Calendar.getInstance();
int curTime = current.getTimeInMillis();
int alarmTime = calendar.getTimeInMillis();
if (alarmTime >= curTime){
manager.setRepeating(AlarmManager.RTC_WAKEUP,
alarmTime, AlarmManager.INTERVAL_DAY, // for repeating
// in every 24
// hours
pendingIntent);
}else{
calendar.add(Calendar.DAY_OF_MONTH, 1);
int alarmTime = calendar.getTimeInMillis();
manager.setRepeating(AlarmManager.RTC_WAKEUP,
alarmTime, AlarmManager.INTERVAL_DAY, // for repeating
// in every 24
// hours
pendingIntent);
}
