替换碎片时关闭当前碎片

Question

下面的代码在点击html链接时打开一个新的片段，我想关闭当前的片段，这样它就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

试着这样做一次！

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

Answer 3

@Garry popBackStack()将不起作用，因为@Jusna Leema将片段添加为：

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

transaction.addToBackStack(null);

简单删除片段应该是有效的。
