Answer 1

您可以获取该片段的Instanceof并设置可见性，即隐藏/显示您要隐藏的布局  if(yourCurrentfragment instanceof first fragment){ findViewById(R.id.support_layout).setVisibility(View.GONE); }

Answer 2

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);
