android – 通知栏显示大图标和小图标

我的应用程序中的通知栏仅显示@L_262_2@收报机中的小图标(应该如此).但是,当“阴影”被拉下时,它会显示@L_262_2@收报机中的小图标,以及我在Notification.builder中设置的大图标.这是我的代码：

if (Build.VERSION.SDK_INT > 10){
            notification = new Notification(R.drawable.ic_stat_mintchip,"This is a test",System.currentTimeMillis());
            notification.largeIcon = (((BitmapDrawablE)c.getresources().getDrawable(R.drawable.ic_launcher)).getBitmap());
            notification.defaults |= Notification.DEFAULT_ALL;
            notification.number += 1;
            notification.flags |= Notification.FLAG_AUTO_CANCEL;

        } else {
            notification = new Notification(R.drawable.ic_stat_mintchip,System.currentTimeMillis());

                notification.flags |= Notification.FLAG_AUTO_CANCEL;
                notification.defaults |= Notification.DEFAULT_ALL;
                notification.number += 1;
        }
}

我不太清楚为什么会这样.任何帮助？

Notification.builder nb = new Notification.builder(context)
    .setContenttitle("title")
    .setContentText("content")
    .setAutoCancel(true)
    .setLargeIcon(largeIcon)
    .setsmallIcon(R.drawable.small_icon)
    .setTicker(s.getText());
notificationmanager nm = (notificationmanager)context.getSystemservice(Context.NOTIFICATION_serviCE);
nm.notify(100,nb.build());
