Моего StatisticsPage.java является:

import android.app.ActionBar; 
import android.content.SharedPreferences; 
import android.os.Bundle; 
import android.preference.PreferenceManager; 
import android.support.v4.app.Fragment; 
import android.support.v4.app.FragmentActivity; 
import android.support.v4.app.FragmentManager; 
import android.support.v4.app.FragmentTabHost; 
import android.support.v4.app.FragmentTransaction; 
import android.support.v7.app.ActionBarActivity; 
import android.util.Log; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.ArrayAdapter; 
import android.widget.Spinner; 
import android.widget.TextView; 

/** 
* Created by Mike on 2/13/14. 
*/ 
public class StatisticsPage extends Fragment { 

    public StatisticsPage(){} 
    private FragmentTabHost mTabHost; 



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

     Spinner spinner = (Spinner) getView().findViewById(R.id.statsSpin); 
     ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(getActivity(), 
       R.array.statspage, android.R.layout.simple_spinner_item); 


     View rootView = inflater.inflate(R.layout.statistics_pagelayout, container, false); 


     SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(getActivity()); 
     String userName = prefs.getString("userName", null); 
     String userID = prefs.getString("userID", null); 
     String url = "myURL"; 
     String userURLComp = "u=" + userID; 


     url = url + userURLComp ; 



     new getBasicStats(getActivity()).execute(url); 




     return rootView; 
    } 





} 

линия 35 is:

Spinner spinner = (Spinner) getView().findViewById(R.id.statsSpin); 

Я пробовал перемещать код счетчика после строки вида корневого просмотра, но без кубиков.

Answer 1

Попробуйте

Spinner spinner = (Spinner) rootView.findViewById(R.id.statsSpin); 

после rootView было назначено
