我有一个关于通知bigcontentview的展开和折叠的问题。
当通知在通知列表的顶部时，它会像Android文档中所述一样展开视图，但是当通知不在通知列表的顶部时，通知视图变得奇怪。我在下面的图片中展示给你看
(很抱歉图片中隐藏了内容)
(1. 折叠视图)
在这个通知中，内容变得不可见
(2. 展开视图)
展开后所有内容都可见，我知道这是正确的行为。
但是我想在通知被折叠时更改布局，这样我就可以更改布局并使其内容可见。
有没有解决方法？我如何知道通知是折叠还是展开？ 如何在展开和折叠时更改布局？以便所有内容都可见。
有没有办法为展开和折叠的通知添加不同的布局？
我的代码如下：：
@SuppressLint("NewApi")
public void updateNotification(String text) {
PendingIntent pendingIntent = null;
PendingIntent pendingIntent1 = null;
PendingIntent pendingIntent2 = null;
PendingIntent pendingIntent3 = null;
PendingIntent pendingIntent4 = null;
PendingIntent pendingIntent5 = null;
if (mRemoteViews == null) {
Log.d("LOG", "mRemoteViews is null");
if (Base.sharedPref.getBoolean("firsttimenotifiation", false)) {
mRemoteViews = new RemoteViews(getPackageName(),
R.layout.custom_notification);
} else {
if (isCurrentBuildabove16()) {
mRemoteViews = new RemoteViews(getPackageName(),
R.layout.customizenotification);
} else {
mRemoteViews = new RemoteViews(getPackageName(),
R.layout.customnotification);
}
}
} else {
if (MusicList.MusicFrom != MusicList.FromNotification) {
if (mState == State.Paused || mState == State.Stopped || mState == State.Stopappnotification) {
try {
Log.e("LOG", "State.Paused || State.Stopped");
mRemoteViews.setImageViewResource(R.id.playpush,
R.drawable.playdetailfornoti);

请帮助我，非常感谢。
