更换碎片时关闭当前碎片

Question

下面这段代码在单击html链接时打开一个新片段，我想关闭当前片段，以便它不会在后台保持打开状态。

  protected boolean isURLMatching(String url) {
        url = "http://bakara2.com";
        // some logic to match the URL would be safe to have here
        return true;
    }

    protected void openNextActivity() {
        Fragment fragment = null;
        fragment = new bakara2();
        replaceFragment(fragment);
    }
    public void replaceFragment(Fragment someFragment) {
        FragmentTransaction transaction = getFragmentManager().beginTransaction();
        transaction.replace(R.id.frame_container, someFragment);
        transaction.addToBackStack(null);
        transaction.commit();
    }

Answer 1

getActivity().getSupportFragmentManager().beginTransaction().remove(this).commit();

Answer 2

尝试这样做一次！

 getActivity().getFragmentManager().popBackStack();

Answer 3

@Garry popBackStack（）因为@Jusna Leema添加片段而无法正常工作：

transaction.replace(R.id.frame_container, someFragment);
transaction.addToBackStack(null);
transaction.commit();

<强> transaction.addToBackStack（空）;

简单的删除片段应该可以工作。
