Question

我正在尝试刷新选定的微调器项目的第一个选项卡，但它显示错误没有查看发现异常显示我何时尝试调用相同的片段。

刷新相同的片段代码：

DashBoardFragment currentFragment = new DashBoardFragment();
    FragmentTransaction fragTransaction = getFragmentManager().beginTransaction();
    //fragTransaction.detach(currentFragment);
    //fragTransaction.attach(currentFragment);
    fragTransaction.replace(R.id.home_container, currentFragment);
    fragTransaction.commit();

public void Refresh() {
    FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
    List<Fragment> fragments = fragmentManager.getFragments();
    for (Fragment fragment : fragments) {
        if (fragment != null && fragment.isVisible()) {
            if (fragment instanceof SummaryReportsFragment) {
                Toast.makeText(getContext(), "Yes", Toast.LENGTH_LONG).show();
                FragmentTransaction fragTransaction = getActivity().getSupportFragmentManager().beginTransaction();
                fragTransaction.detach(fragment);
                fragTransaction.attach(fragment);
                fragTransaction.commit();
            }
