我有一個(gè)名為 ParserService 的意圖服務(wù)，它執(zhí)行一些任務(wù)并創(chuàng)建一個(gè)可打包的對(duì)象（ArtistInfo）。然后它檢查應(yīng)用程序是否在前臺(tái)。如果是，則它會(huì)在意圖附加項(xiàng)中發(fā)送帶有可分割對(duì)象的廣播。此廣播由活動(dòng) MainActivity.java 接收，然后該活動(dòng)創(chuàng)建具有相同對(duì)象的意圖，并啟動(dòng)名為 ListSongsActivity 的活動(dòng)，在該活動(dòng)中成功接收了 Parcelable 對(duì)象。但是，如果應(yīng)用程序不在前臺(tái)，則 ParserService 會(huì)發(fā)送一個(gè)通知，其意圖與廣播的意圖相同。但是當(dāng) ListSongsActivity 通過通知啟動(dòng)時(shí)，parcelable 對(duì)象（ArtistInfo）這次為空。我也在意圖中傳遞一個(gè)字符串。該字符串通過通知意圖正確接收，但parcelable 對(duì)象為空。請(qǐng)?jiān)谙旅嬲业较嚓P(guān)的代碼片段。來自 ParserService 的廣播和通知代碼：if (CommonUtils.appInForeground(getApplicationContext())) { Log.d(TAG, "onHandleIntent(): Sending success broadcast."); sendBroadcast(createSuccessIntent(artistInfo)); } else { // TODO: 10-10-2018 tapping on notification does nothing!! Log.d(TAG, "onHandleIntent(): Sending success notification."); String body = "Parsing complete for the url: " + url; Intent notifyIntent = new Intent(getApplicationContext(), ListSongsActivity.class); notifyIntent.putExtra(Constants.MUSIC_SITE, siteName); notifyIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK); Bundle bundle = new Bundle(); bundle.putParcelable(Constants.PARSED_ARTIST_INFO, artistInfo); intent.putExtras(bundle); CommonUtils.sendNotification(getApplicationContext(), Constants.LIST_SONGS_NOTIFICATION_TITLE , body, Constants.LIST_SONGS_NOTIFICATION_CHANNEL_ID, notifyIntent, Constants.LIST_SONGS_NOTIFICATION_ID, R.drawable.ic_launcher_background); }private Intent createSuccessIntent(ArtistInfo artistInfo) { Intent intent = new Intent(); intent.setAction(Constants.PARSE_SUCCESS_ACTION_KEY); Bundle bundle = new Bundle(); bundle.putParcelable(Constants.PARSE_SUCCESS_MESSAGE_KEY, artistInfo); intent.putExtras(bundle); return intent;}

在調(diào)用sendNotification()else 條件之前，您將 bundle 置于不同的intent，而不是notifyIntent。在 else 中更改您的代碼，如下所示
else {
// TODO: 10-10-2018 tapping on notification does nothing!!
Log.d(TAG, "onHandleIntent(): Sending success notification.");
String body = "Parsing complete for the url: " + url;
Intent notifyIntent = new Intent(getApplicationContext(), ListSongsActivity.class);
notifyIntent.putExtra(Constants.MUSIC_SITE, siteName);
notifyIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
Bundle bundle = new Bundle();
bundle.putParcelable(Constants.PARSED_ARTIST_INFO, artistInfo);
notifyIntent.putExtras(bundle);
CommonUtils.sendNotification(getApplicationContext(), Constants.LIST_SONGS_NOTIFICATION_TITLE
, body, Constants.LIST_SONGS_NOTIFICATION_CHANNEL_ID, notifyIntent,
Constants.LIST_SONGS_NOTIFICATION_ID, R.drawable.ic_launcher_background);
}

也許您正在創(chuàng)建的待處理意圖比應(yīng)用程序中的要多。在這種情況下，您應(yīng)該使用，
PendingIntent.FLAG_CANCEL_CURRENT
從頭開始創(chuàng)建 Intent 并擴(kuò)充您的包
