1.在NotificationTransaction.java裏增加新的變量如下：
private static final int WAKE_LOCK_TIMEOUT = 5000;
private static PowerManager.WakeLock mWakeLock;
2.修改NotificationTransaction.updateNewMessageIndicator方法
public static void updateNewMessageIndicator(Context context, boolean isNew) {
Log.d(TAG, "updateNewMessageIndicator, isNew = " + isNew);
SortedSet accumulator =
new TreeSet(INFO_COMPARATOR);
Set threads = new HashSet(4);
PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
mWakeLock = pm.newWakeLock(PowerManager.SCREEN_BRIGHT_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP, "updateNewMessageIndicator");
mWakeLock.setReferenceCounted(true);
int count = 0;
count += accumulateNotificationInfo(
accumulator, getMmsNewMessageNotificationInfo(context, threads));
count += accumulateNotificationInfo(
accumulator, getSmsNewMessageNotificationInfo(context, threads));
cancelNotification(context, NOTIFICATION_ID);
if (!accumulator.isEmpty()) {
accumulator.first().deliver(context, isNew, count, threads.size());
}
mWakeLock.acquire(WAKE_LOCK_TIMEOUT);
}
3.根據自己的需要來定義WAKE_LOCK_TIMEOUT的時間長短。
如果需要按鍵燈和屏幕都亮，則修改PowerManager.SCREEN_BRIGHT_WAKE_LOCK屬性為PowerManager.FULL_WAKE_LOCK屬性。
