我目前正在研究
Android Support Package v4 Rev 10的NotificationCompat功能.
documentation表示’setContentText()’显示通知中的第二行.这适用于API 8直到API 15.但是,如果我尝试在API 16中使用此方法,我的通知将错过第二行.我只看到标题而不是第二行.添加多行是没有问题的(使用’addline()’).
这是我使用的NotificationCompat.Builder的代码：
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;
}
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());
这是Jelly Bean的想要功能,setContentText被忽略还是我错过了什么？代码在没有错误的所有版本上运行,但我想添加第二行,使用与ICS或更早版本相同的代码.
我还添加了两个截图.第一个来自我的ICS 4.0.3华为MediaPad,第二个来自Galaxy Nexus和4.1.1.从1开始的第二行是简单的与通知标题相同的字符串.它在2不可见.
感谢您的帮助！
