有几种方法。如果您能添加一些代码作为参考就更好了。
第一种方法是在片段中添加一个方法，将可见性设置为“gone”。在您的活动中，您可以通过getSupportFragmentManager().findFragmentById(<container - id>)获取片段的实例，然后调用片段的方法。
第二种方法可以使用接口来实现。
英文:
There can be a couple of ways. It would nice if you add some code for the reference.
1st way would be to have a method in the fragment which would have the set the visibility to gone in fragment. In you activity you can get the instance of the fragment by this getSupportFragmentManager().findFragmentById(<container - id>) and then just call the fragment method.
2nd way could be using interface to this.
