我目前正在寻找到Android的支持包V4版本10. documentation说，'setContentText（）'示出了在通知中的第二行。这是API 8真正达到API 15。但是，如果我尝试用这种方法在API 16我的通知将错过第二行。我只看到标题，但不是第二行。添加多个行是没有问题的（利用'addline（）'）

下面是我的code为我所用的NotificationCompat.Builder：

 私人NotificationCompat.Builder buildNormal（CharSequence的pTitle）{    NotificationCompat.Builder建设者=新NotificationCompat.Builder（            getSherlockActivity（））;    builder.setAutoCancel（真）.setDefaults（Notification.DEFAULT_ALL）;    //设置显示日期    builder.setWhen（System.currentTimeMillis的（））;    //通知的标题    builder.setContentTitle（pTitle）;    //设置pre API 16台设备的文本    builder.setContentText（pTitle）;    //设置行动点击通知    builder.setContentIntent（buildPendingIntent（Settings.ACTION_SECURITY_SETTINGS））;    //设置图标的通知    builder.setSmallIcon（android.R.drawable.stat_sys_download_done）;    //设置它运行在托盘几秒钟，小股票的文字    builder.setTicker（这是你的股票的文字。）;    //设置优先级为API 16台设备    builder.setPriority（Notification.PRIORITY_DEFAULT）;    返回建设者;} 

如果我想添加多行，并显示该通知，我用这个code：

  NotificationCompat.Builder正常= buildNormal（这是一个扩展的布局通知）;    NotificationCompat.InboxStyle大=新NotificationCompat.InboxStyle（            正常）;    //摘要的作用下    big.setSummaryText（这是摘要文本）;    //线是上方的动作和标题下方    big.addLine（这是第一行）。addLine（第二行）            .addLine（第三线）addLine（第四线）。    NotificationManager经理= getNotificationManager（正常）;    manager.notify（Constants.NOTIFY_ID，big.build（））; 

这是果冻豆的通缉的特点，那setContentText被忽略还是我失去了一些东西？在code上的所有版本没有错误运行，但我想用相同的code我在ICS使用添加第二个行或更早版本。

我还添加了两个截图。从我的ICS 4.0.3华为MediaPad的第一和从Galaxy Nexus的第二4.1.1。从 1 第二行是为了简单起见，相同的字符串作为通知的标题。这不是在 2 可见。

感谢您的帮助提前！

的 setContextText（）应该是在折叠状态下可见的（例如，双指轻扫了，如果扩大，或有它不是最顶层的通知）。它将由 NotificationCompat.InboxStyle 在扩展状态下进行更换，给您code以上。

I'm currently looking into the NotificationCompat features of the Android Support Package v4 Rev 10. The documentation says that 'setContentText()' shows the second row in a notification. This is true for API 8 up to API 15. However, if I try to use this method in API 16 my Notifications will miss the second line. I see only the Title but not the second line. Adding multiple lines is no problem (using 'addline()').

Here's my code for the NotificationCompat.Builder I used:

private NotificationCompat.Builder buildNormal(CharSequence pTitle) {
    NotificationCompat.Builder builder = new NotificationCompat.Builder(
            getSherlockActivity());

    builder.setAutoCancel(true).setDefaults(Notification.DEFAULT_ALL);
    // set the shown date
    builder.setWhen(System.currentTimeMillis());
    // the title of the notification
    builder.setContentTitle(pTitle);
    // set the text for pre API 16 devices
    builder.setContentText(pTitle);
    // set the action for clicking the notification
    builder.setContentIntent(buildPendingIntent(Settings.ACTION_SECURITY_SETTINGS));
    // set the notifications icon
    builder.setSmallIcon(android.R.drawable.stat_sys_download_done);
    // set the small ticker text which runs in the tray for a few seconds
    builder.setTicker("This is your ticker text.");
    // set the priority for API 16 devices
    builder.setPriority(Notification.PRIORITY_DEFAULT);
    return builder;
}

And if I want to add multiple lines and show the notification, I uses this code:

NotificationCompat.Builder normal = buildNormal("This is an Expanded Layout Notification.");
    NotificationCompat.InboxStyle big = new NotificationCompat.InboxStyle(
            normal);

    // summary is below the action
    big.setSummaryText("this is the summary text");
    // Lines are above the action and below the title
    big.addLine("This is the first line").addLine("The second line")
            .addLine("The third line").addLine("The fourth line");

    NotificationManager manager = getNotificationManager(normal);
    manager.notify(Constants.NOTIFY_ID, big.build());

Is this a wanted feature of Jelly Bean, that setContentText is ignored or am I missing something? The code runs on all versions without errors, but I would like to add the second line with the same code I use on ICS or earlier.

I've also added two screenshots. the first from my ICS 4.0.3 Huawei MediaPad and the second from a Galaxy Nexus with 4.1.1. The second line from 1 is for simplicity the same String as the notification title. It is not visible on 2.

Thanks for your help in advance!

The value of setContextText() should be visible in the collapsed state (e.g., two-finger swipe up if expanded, or have it not be the top-most Notification). It will be replaced by NotificationCompat.InboxStyle in the expanded state, given your code above.
