您可以获取该片段的实例并设置可见性，即隐藏/显示要隐藏的布局

if（第一个片段的当前片段实例）{
findviewbyd（R.id.support\u布局）.setVisibility（View.go）；
}

尝试以下代码：

View supportLayout = findViewById(R.id.support_layout);// write this in your activity and dont forget to make supportLayout public

((YourActivity)getActivity()).supportLayout.setVisibility(View.GONE);

findViewById（R.id.support\u布局）。设置可见性（View.go）我尝试过，但给出了空指针异常，只想隐藏第一个片段
