Question

我已经实现了一个BigTextStyle / InboxStyle通知，但它显示为正常的通知，它显示在我的HTC One X AT＆amp; T（4.1.1）上的JellyBean（在Gingerbread，ICS等中）之前。甚至动作按钮也没有显示。

我已经使用模拟器检查了我的代码（使用JellyBean 4.2），这样做有效。

看起来我的HTC One X版本没有实现JellyBean的新通知系统。

HTC One X AT＆amp; T设备信息

Android Version - 4.1.1 
HTC Sense Version - 4+ 
Software number - 3.18.502.6 710RD 
HTC SDK API Level - 4.63 
HTC Extension version - HTCExtension_Sesnse45_2

源代码

@TargetApi(Build.VERSION_CODES.JELLY_BEAN)
private void showNotificationJB(Reminder reminder, Intent intent) {

    Log.v(TAG, "Showing BigText Notification");

    Notification.Builder builder = new Notification.Builder(this);
    builder.setContentTitle("Ezeetrak Scheduler");

    AdditionalDataStore store = reminder.getStore(); 

    String passedBy = store.optString("passedBy");

    builder.setContentText("Recieved an Event by " + passedBy);
    builder.setTicker("Recieved an Event by " + passedBy);
    builder.setSmallIcon(R.drawable.ic_launcher);

    Notification.InboxStyle inboxStyle = new Notification.InboxStyle();
    inboxStyle.addLine(Html.fromHtml("<b>Name: </b>" + reminder.getEventName()));
    inboxStyle.addLine(Html.fromHtml("<b>Date: </b>" + DateTimeHelper.DateFormat.format(reminder.getEventDate())));
    inboxStyle.addLine(Html.fromHtml("<b>Time: </b>" + reminder.getEventTimeFormatted()));
    inboxStyle.addLine(Html.fromHtml("<b>Sent By: </b>" + passedBy));
    inboxStyle.setBigContentTitle("Ezeetrak Scheduler");

    builder.setStyle(inboxStyle);

    PendingIntent acceptPendingIntent = buildPendingIntent(ReminderActivity.ACTION_ACCEPT, intent, 0);
    PendingIntent rejectPendingIntent = buildPendingIntent(ReminderActivity.ACTION_REJECT, intent, 1);

    builder.setContentIntent(buildPendingIntent(ReminderActivity.ACTION_VIEW, intent, 2));
    builder.addAction(R.drawable.ic_action_accept, "Accept", acceptPendingIntent);
    builder.addAction(R.drawable.ic_action_reject, "Reject", rejectPendingIntent);
    builder.setAutoCancel(false);

    NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    notificationManager.notify(REMINDER_SHARE_ACTION, builder.build());
}

有谁知道为什么它不能用于我的设备？

Answer 1

Android 4.1中的BigTextStyle通知需要两根手指才能展开它。

在Android 4.2中，只需要一根手指。请参阅视频以供参考。 http://www.youtube.com/watch?v=a6dzMzklEd4

Answer 2

尝试使用NotificationCompat.Builder代替Notification.Builder。相应地更改您的代码。这应该有效。此帖的其他答案是重要。
