Answer 1

如果您想更改通知中显示的图标，请尝试更改

// notification icon
    final int icon = R.mipmap.ic_logo;

例如，如果您在**new_logo**文件夹中有Drawable图片，请将其更改为下方 -

final int icon = R.drawable.new_logo;

更改您的代码：

notification = mBuilder
            .setSmallIcon(icon)
            .setTicker(title).setWhen(0)
            .setAutoCancel(true)
            .setContentTitle(title)
            .setContentIntent(resultPendingIntent)
            .setSound(alarmSound)
            .setStyle(inboxStyle)
            .setWhen(getTimeMilliSec(timeStamp))
            .setSmallIcon(R.mipmap.ic_logo)
            .setLargeIcon(BitmapFactory.decodeResource(mContext.getResources(), icon))
            .setContentText(message)
            .build();

要：

notification = mBuilder
            .setSmallIcon(icon)
            .setTicker(title).setWhen(0)
            .setAutoCancel(true)
            .setContentTitle(title)
            .setContentIntent(resultPendingIntent)
            .setSound(alarmSound)
            .setStyle(inboxStyle)
            .setWhen(getTimeMilliSec(timeStamp))
            .setLargeIcon(BitmapFactory.decodeResource(mContext.getResources(), icon))
            .setContentText(message)
            .build();

我看到您多次设置mBuilder.setSmallIcon。

尝试一次。

NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.mipmap.your_icon)
                .setContentTitle("Firebase Push Notification")
                .setContentText(messageBody)
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);

        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(0, notificationBuilder.build());

无法使用Firebase ICON android更改我的通知
