Question

我正在使用Bundle对象将jsonobject一个片段解析为另一个fragment。但是当运行App时它会崩溃..任何人都可以帮助我....

片段1

在使用Async任务使用按钮获取我的jsonobject后，打开我的第二个片段

public void onClick(View v) {
        Log.d(TAG,"More button clicked");
        Fragment_account_details fragment = new Fragment_account_details();

        Bundle bundle = new Bundle();
        String accountDetails = name_value_list.toString();
        bundle.putString("accountDetails", accountDetails);
        fragment.setArguments(bundle);

        getFragmentManager()
        .beginTransaction()
        .replace(R.id.content_frame, fragment.newInstance(),
                fragment.TAG).commit();
    };

片段2

public class Fragment_account_details extends Fragment {

    TextView name, officePhone,fax,email;

    public static Fragment_account_details newInstance() {
        return new Fragment_account_details();
    }

    public final static String TAG = Fragment_account_details.class
            .getSimpleName();

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_account_details, container,false);

        name = (TextView) rootView.findViewById(R.id.text_name);
        fax = (TextView) rootView.findViewById(R.id.text_fax);
        email = (TextView) rootView.findViewById(R.id.text_email);

        String accountDetails = getArguments().getString("accountDetails");


        return rootView;


    }

}

logcat的
