我想要做的是,当您访问“short”选项卡时,它将加载“short.php”,当您访问“images”时,它将加载“images.php”等。我该如何让它工作?

我可能遗漏了一些东西,但它不仅仅是向 DummySectionFragment 添加一个静态方法:

 public static DummySectionFragment newInstance(String loadurl) {
    DummySectionFragment frag = new DummySectionFragment();
    Bundle bundle=new Bundle();
    bundle.putString("url", loadurl);

    frag.setArguments(bundle);

    return frag;
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
    Bundle savedInstanceState) {

    final String url=getArguments().getString("url");

    View rootView = inflater.inflate(R.layout.fragment_main_dummy,container, false);
    WebView wv = (WebView)rootView.findViewById(R.id.webView);
    wv.loadUrl("http://dns.themeister.se/"+url+".php");
    return rootView;
    }
}

接着:

@Override
public Fragment getItem(int position) {
    // getItem is called to instantiate the fragment for the given page.
    // Return a DummySectionFragment (defined as a static inner class
    // below) with the page number as its lone argument.

    return DummySectionFragment.newInstance(getPageTitle(position).toString());
}
