android - 应用程序被杀死时Android通知操作按钮不起作用

问题描述

我正在创建我的第一个 android 应用程序，它是一个词汇测验。我正在尝试每小时发送一次通知（使用 PeriodicWorkRequest - WorkManager）。我注意到，当应用程序被终止时，通知会不断启动，但操作按钮不起作用。

这是我的 Worker 类中的发送通知方法：

public void sendNot(Word word, int wordNum) {
            Intent activityIntent = new Intent(getApplicationContext(), WordStatsActivity.class);
            activityIntent.putExtra("word_exists", word);
            PendingIntent contentIntent = PendingIntent.getActivity(getApplicationContext()
                    , 0, activityIntent, PendingIntent.FLAG_UPDATE_CURRENT);

            Intent knewBroad = new Intent(getApplicationContext(), MainActivity.NotificationBroadcast.class);
            knewBroad.setAction(KNEW_WORD);
            knewBroad.putExtra("word", word);
            PendingIntent knewIntent = PendingIntent.getBroadcast(getApplicationContext(),
                    0, knewBroad, PendingIntent.FLAG_UPDATE_CURRENT);

            Intent didntKnowBroad = new Intent(getApplicationContext(), MainActivity.NotificationBroadcast.class);
            didntKnowBroad.setAction(DIDNT_KNOW_WORD);
            didntKnowBroad.putExtra("word", word);
            PendingIntent didntKnow = PendingIntent.getBroadcast(getApplicationContext(),
                    0, didntKnowBroad, PendingIntent.FLAG_UPDATE_CURRENT);

            Intent stopShowBroad = new Intent(getApplicationContext(), MainActivity.NotificationBroadcast.class);
            stopShowBroad.setAction(NOTIFCATION_OFF);
            stopShowBroad.putExtra("word", word);
            PendingIntent stopShowIntent = PendingIntent.getBroadcast(getApplicationContext(),
                    0, stopShowBroad, PendingIntent.FLAG_UPDATE_CURRENT);


            Notification notification = new NotificationCompat.Builder(getApplicationContext(), CHANNEL_1_ID)
                    ...
                    .addAction(R.mipmap.ic_launcher, "know", knewIntent)
                    .addAction(R.mipmap.ic_launcher, "don't know", didntKnow)
                    .addAction(R.mipmap.ic_launcher, "don't show again", stopShowIntent)
                    ...
                    .build();
            notificationManager.notify(word.getId(), notification);
        }

解决方案

确保在您的推送通知负载中，通知键不能存在。只有数据键将出现在有效负载正文中。

不使用这个（示例）

{
    "to": "a6345d0278adc55d3474f5",
    "data": {
        "message": "Hello World!"
    },
    "notification": {
        "body": "Hello World \u270c",
        "badge": 1,
        "sound": "ping.aiff"
    }
}

而是使用这个（示例）：

{
    "to": "a6345d0278adc55d3474f5",
    "data": {
        "message": "Hello World!"
    }
}
