Android通知大内容视图：扩展和折叠时的不同布局

Question

我对通知bigcontentview的扩展和崩溃有一些问题。

当通知在通知列表的顶部时，有如android文档中所述的扩展视图，但是当通知不在通知列表的顶部时，通知视图变得奇怪。我在图中向您展示

（对不起隐藏图片中的内容）

（1.折叠视图）

在此通知中，内容变得不可见

（2.扩展视图）

展开后所有内容都可见，我知道这是正确的行为。

但我希望在通知崩溃时更改布局。所以我可以改变布局和内容可见

有什么解决方案吗？如何让通知折叠或展开？如何在展开和折叠期间更改其布局？所有内容都可见。

有没有办法为展开和折叠通知添加不同的布局？

我的代码低于：

请提前帮助我

我同时设置了大视图和普通视图，并允许通过展开和折叠来切换两者。

然而另一个问题是大视图：如果我设置大视图，每次更新通知时都会闪烁..
