您可以从实际的ListView中删除AllView（），而不仅仅是清除适配器。。。试一试

((ListBitmapsFragment)fragment).getListView().removeAllViews()

多亏了Atomix，我找到了这个问题的解决方案——在方法callTheFragment（）中，我做了一些更改：我在容器中使用了关于片段的信息，并在该信息之后删除了它，如果该片段已经退出的话，同时我在片段中找到了视图组（容器），并清除了它的所有视图。它是有效的。 谢谢 埃里克D

您好，Atomix，我将尝试发布反馈。此方法不受支持，调用时抛出UnsupportedOperationException。
