我试图从 Fragment 中的网站获取数据但不起作用，错误是 android.os.NetworkOnMainException
fetchData() 期间的进程错误；
Tab2Fragment.java
public class Tab2Fragment extends Fragment {
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
if (container == null) {
return null;
}
Log.i("Tab2","Creating Tab 2" );
LinearLayout li = (LinearLayout) inflater.inflate(R.layout.tab_frag2_layout, container, false);
try {
fetchData();
} catch (IOException e) {
}
return li;
}
public void fetchData() throws IOException{
Log.i("Fetching!","JSOUP");
try{
HttpClient client = new DefaultHttpClient();
String URL = "http://";
HttpGet request = new HttpGet(URL);
HttpResponse response = client.execute(request);
String html = "";
InputStream in = response.getEntity().getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(in));
StringBuilder str = new StringBuilder();
String line = null;
while((line = reader.readLine()) != null)
{
str.append(line);
}
in.close();
html = str.toString();
setTexts(html);
}
catch(Exception e){
Log.i("Error!","JSOUP");
}
}
我应该怎么做才能将网站数据提取到碎片化的选项卡中。
