Android 订单列表多个同名fragment里的刷新组件无法使用

Question

以下编码，只有第一个fragment里的刷新组件能触发，其他四个都不行

RefreshLayout refreshLayout = getActivity().findViewById(R.id.refreshLayout);
DebugLogUtil.getInstance().Debug("测试 .." + refreshLayout.toString());
refreshLayout.setRefreshHeader(new ClassicsHeader(getContext()));
refreshLayout.setRefreshFooter(new ClassicsFooter(getContext()));
refreshLayout.setEnableLoadMoreWhenContentNotFull(false);
refreshLayout.setOnRefreshListener(refreshlayout -> {
    page = 1;
    list = new ArrayList<>();
    req();
    refreshlayout.finishRefresh(1000/*,false*/);//传入false表示刷新失败
});

ticketFrag = new OrderFrag(0);
        ticketFrag1 = new Order1Frag(1);
        ticketFrag2 = new Order2Frag(2);
        ticketFrag3 = new Order3Frag(3);
        ticketFrag4 = new Order4Frag(4);
        fragmentList.add(ticketFrag);
        fragmentList.add(ticketFrag1);
        fragmentList.add(ticketFrag2);
        fragmentList.add(ticketFrag3);
        fragmentList.add(ticketFrag4);
//        mPagerAdapter.addFragment(ticketFrag);
//        mPagerAdapter.addFragment(ticketFrag1);
//        mPagerAdapter.addFragment(ticketFrag2);
//        mPagerAdapter.addFragment(ticketFrag3);
//        mPagerAdapter.addFragment(ticketFrag4);
 String[] title = {"全部", "待付款", "待发货", "待收货", "待评价"};
        adapter = new MyPagerAdapter(getSupportFragmentManager(), fragmentList, title);
        viewPager.setAdapter(adapter);
        mTabLayout.setupWithViewPager(viewPager);

我自己的方案是Fragment不新建，仍然用同名的 ，用多个不同名但是内容相同的layout，去区分开不同的刷新组件的id，问题解决，但是我是想通过在fragment内部下功夫解决，有无大佬指示
