我研究了这个,发现它addAction (int icon, CharSequence title, PendingIntent intent)已被弃用,所以我用过addAction (Notification.Action action).在这两种情况下,都无法看到图标.

NotificationCompat.Action action = new NotificationCompat.Action.Builder(R.drawable.ic_share, "", pendingIntent).build();

notificationBuilder.addAction(action);

文本似乎工作,但我把它留空了,因此在主图像下面有一个空的空间,其中应该显示图标

随着Android 26(O)推出通知渠道,我一直在调查谷歌提供的 com.example.android.notificationchannels

此示例按预期工作,直到我尝试添加Action到示例应用程序中定义的辅助通知.

我的代码类似于: -

   /**
     * Build notification for secondary channel.
     *
     * @param title Title for notification.
     * @param body Message for notification.
     * @return A Notification.Builder configured with the selected channel and details
     */
    @RequiresApi(api = Build.VERSION_CODES.O)
    public Notification.Builder getNotification2(String title, String body) {
        return new Notification.Builder(getApplicationContext(), SECONDARY_CHANNEL)
                .setContentTitle(title)
                .setContentText(body)
                .setActions(buildAction())
                .setSmallIcon(getSmallIcon())
                .setAutoCancel(true);
    }

和buildAction(): -

   @TargetApi(Build.VERSION_CODES.KITKAT_WATCH)
    private Notification.Action buildAction() {

        final Intent intent = new Intent(this, SecondActivity.class);
        final PendingIntent pendingIntent =  PendingIntent.getActivity(this, 1729, …
