的電話，但不是在模擬器

聯繫人選擇器的應用程序崩潰，所以我必須從Android的約紗廠此示例代碼，我修改了一些顯示通訊錄中的紡織家之一，並在其上正常工作的模擬器，它顯示5項我的聯繫人添加，但在手機上崩潰權在啓動時，我無法理解從logcat的話，這可能是錯了嗎？這裏，S代碼的電話，但不是在模擬器

// add items into spinner dynamically 
    public void addItemsOnSpinner2() { 
     spinner2 = (Spinner) findViewById(R.id.spinner2); 
     list = new ArrayList<String>(); 
     getContacts(null); 
     ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, list); 
     dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 
     spinner2.setAdapter(dataAdapter); 
    } 

    private String getContacts(String contact) { 

     people = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null); 
     while (people.moveToNext()) { 
      int nameFieldColumnIndex = people.getColumnIndex(PhoneLookup.DISPLAY_NAME); 
      contact = people.getString(nameFieldColumnIndex); 
      list.add(contact); 
     } 
     people.close(); 
     return contact; 
    }

，這是logcat的

爲什麼你在'getContacts（null）'方法中傳遞'null'？如果它的字符串，你應該通過'「」'（雙引號）代替。 –

還是你的活動一樣.. –

什麼名字？ –

原來在我的手機是空（NULL），誰知道爲什麼......我固定它像第一個條目這個

public void getContacts() { 

     people = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null); 
     while (people.moveToNext()) { 
      int nameFieldColumnIndex = people.getColumnIndex(PhoneLookup.DISPLAY_NAME); 
      String s = people.getString(nameFieldColumnIndex); 
      if (s != null) 
       list.add(s); 
     } 
     people.close(); 
    }
