我正在尝试在片段中添加一个TabHost ...代码是在下面给出的.在Fragment里面我试图添加TabHost来显示两个Tab

public class TablesFragment extends Fragment {

TabHost tabHost;
TabHost.TabSpec spec;

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

    View rootView = inflater.inflate(R.layout.tables_fragment, container,
            false);
    tabHost = (TabHost) rootView.findViewById(android.R.id.tabhost);
    tabHost.setup();

    Intent intentAndroid = new Intent().setClass(getActivity(),
            NewsFragment.class);
    spec = tabHost.newTabSpec("Android").setContent(intentAndroid)
            .setIndicator("Android");
    tabHost.addTab(spec);

    Intent intentBus = new Intent().setClass(getActivity(), NewsFragment.class);
    spec = tabHost.newTabSpec("Welcome").setIndicator("Welcome")
            .setContent(intentBus).setIndicator("Welcome");
    tabHost.addTab(spec);
    return rootView;
}

}

这给了我错误...需要这个代码的助手......

从互联网文本数据加载并链接到图像.我无法理解如何在listview中加载图像.阅读,它需要使用毕加索或通用图像加载器,但不明白如何.请更正我的代码

    public class JsonReadTask extends AsyncTask<String, Void, String> {

      @Override
      protected String doInBackground(String... params) {
       HttpClient httpclient = new DefaultHttpClient();
       HttpPost httppost = new HttpPost(params[0]);
       try {
        HttpResponse response = httpclient.execute(httppost);
        jsonResult = inputStreamToString(
          response.getEntity().getContent()).toString();
       }

       catch (ClientProtocolException e) {
        e.printStackTrace();
       } catch (IOException e) {
        e.printStackTrace();
       }
       return null;
      }

      private StringBuilder inputStreamToString(InputStream is) {
       String rLine = "";
       StringBuilder answer = new StringBuilder();
       BufferedReader rd = new BufferedReader(new InputStreamReader(is));
