我需要将String数据从activity传递给fragment。 我不知道为什么,但是当我尝试在片段中传递数据时,对象束为空。
提前感谢您的帮助!
我告诉你我的代码:
活动:
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject c = jsonArray.getJSONObject(i);
// title_array.add(c.getString("title").toString());
url_pdf=c.getString("url_pdf");
SixFragment feedBackFragment =new SixFragment();
Bundle bundle = new Bundle();
bundle.putString("key", url_pdf);
// set Fragmentclass Arguments
feedBackFragment.setArguments(bundle);
}
FRAGMENT:
public class SixFragment extends android.support.v4.app.Fragment {
String url_pdf="";
SimpleAdapter adapter;
ListView list;
ArrayList<HashMap<String, String>> pdfList;
HashMap<String, String> pdf;
String data="";
String arg="";
TextView azz;
String azzzz;
public SixFragment() {
// Required empty public constructor
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_six, container, false);
Bundle bundle = getArguments();
System.out.println("ARGUMENTS:" + bundle);
if (bundle != null) {
arg = bundle.getString("key");
System.out.println("PDF FETCHHHHHHHHH:"+arg);
}
return view;
}
}
