Знакомство с Android-контактами Исключение курсора

Question

Я пытаюсь получить номер контакта, который пользователь выбирает. Проблема заключается в том, когда контакт выбран из списка, он бросает это исключение:

android.database.CursorIndexOutOfBoundsException: Индекс 0 просил, с размером 0

Это происходит с любым контактом, даже те, с несколько телефонных номеров.

Единственные примеры, которые открыли список контактов для меня:

Pick a Number and Name From Contacts List in android app

How to read contacts on Android 2.0

Android contacts database giving me an exception

Они производят ту же ошибку, для меня.

Мой код:

Вызов намерения

public void pickPerson(View V) 
{ 
    Intent intent = new Intent(Intent.ACTION_PICK, 
           ContactsContract.Contacts.CONTENT_URI); 
    intent.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_TYPE); 
    startActivityForResult(intent, PICK_CONTACT); 
} 

Получение номера телефона

//Declcared earlier 
static final int PICK_CONTACT=1; 

@Override 
public void onActivityResult(int reqCode, int resultCode, Intent data) 
{ 
    super.onActivityResult(reqCode, resultCode, data); 

    switch (reqCode) 
    { 
     case (PICK_CONTACT) : 
     { 
      if (resultCode == Activity.RESULT_OK) 
      { 

       Uri contactData = data.getData(); 
       Cursor c = getContentResolver().query(contactData, null, null, null, null); 
       if (c.moveToFirst()) 
       { 
        String id =c.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts._ID)); 

        String hasPhone =c.getString(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)); 

        if (hasPhone.equalsIgnoreCase("1")) 
        { 
         Cursor phones = getContentResolver().query( 
           ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null, 
           ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ id, 
           null, null); 
         phones.moveToFirst(); 
         String cNumber = phones.getString(phones.getColumnIndex(PhoneLookup.NUMBER)); 
         phone.setText(cNumber); //EditText view 
        } 
       } 
      } 
      break; 
     } 
    } 
}

Answer 1

вы можете попробовать это String cNumber = phones.getString(phones.getColumnIndex("data1"));

Answer 2

попробовать это ...

public class ReadContacts extends AsyncTask<Void, Void, Void>{ 

    private ListView contactsList; 

    private Context cntx; 
    private Constant constants; 

    static final String[] CONTACTS_SUMMARY_PROJECTION = new String[] { 
     Contacts._ID, // 0 
     Contacts.DISPLAY_NAME, // 1 
     Contacts.STARRED, // 2 
     Contacts.TIMES_CONTACTED, // 3 
     Contacts.CONTACT_PRESENCE, // 4 
     Contacts.PHOTO_ID, // 5 
     Contacts.LOOKUP_KEY, // 6 
     Contacts.HAS_PHONE_NUMBER, // 7 
    }; 

    private long contactId; 
    private String display_name; 
    private String phoneNumber; 

    private ArrayList<ContactsWrapper>contactWrap = new ArrayList<ContactsWrapper>(); 
    private HashMap<Long, ArrayList<ContactsWrapper>>map = new HashMap<Long, ArrayList<ContactsWrapper>>(); 

    private ContactsAdapter adapter; 

    private DataController controller; 

    public ReadContacts(Context cntx, ListView contactList) { 
     // TODO Auto-generated constructor stub 
     this.cntx = cntx; 
     constants = new Constant(); 
     this.contactsList = contactList; 

     controller = DataController.getInstance(); 
    } 

    @Override 
    protected void onPreExecute() { 
     // TODO Auto-generated method stub 
     super.onPreExecute(); 
     if(!(controller.contactWrapper.size()>0)) 
      constants.displayProgressDialog(cntx, "Loading Contacts...", "Please Wait"); 
    } 

    @Override 
    protected Void doInBackground(Void... params) { 
     // TODO Auto-generated method stub 

     if(!(controller.contactWrapper.size()>0)) 
     { 
     try { 
      String select = "((" + Contacts.DISPLAY_NAME + " NOTNULL) AND (" 
        + Contacts.HAS_PHONE_NUMBER + "=1) AND (" 
        + Contacts.DISPLAY_NAME + " != ''))"; 

      Cursor c = cntx.getContentResolver().query(Contacts.CONTENT_URI, CONTACTS_SUMMARY_PROJECTION, select, 
        null, Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC"); 

      int colorcounter = 0; 
      String[] colorcounter_array = { "#91A46B", "#8BB6B5", "#CAA973", "#8DA6C8","#D19B8D"}; 

      int color_string; 
      for(int i=0;i<c.getCount();i++) 
      { 
//    contactWrap.clear(); 
       try { 
        contactId = 0; 
        String hasPhone = ""; 
        display_name = ""; 
        phoneNumber = ""; 

        c.moveToPosition(i); 

        contactId = c.getLong(0); 
        display_name = c.getString(1); 
        hasPhone = c.getString(7); 

        if (hasPhone.equalsIgnoreCase("1")) 
         hasPhone = "true"; 
        else 
         hasPhone = "false" ; 

        if (Boolean.parseBoolean(hasPhone)) 
        { 
         Cursor phones = cntx.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId,null, null); 
         while (phones.moveToNext()) 
         { 
          int indexPhoneType = phones.getColumnIndexOrThrow(Phone.TYPE); 
          String phoneType = phones.getString(indexPhoneType); 

          phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); 

          String lookupKey = phones.getString(phones.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY)); 

          if (colorcounter < 5) 
          { 
           color_string =Color.parseColor(colorcounter_array[colorcounter]); 
           colorcounter++; 
          } else { 
           colorcounter = 0; 
           color_string =Color.parseColor(colorcounter_array[colorcounter]); 
           colorcounter++; 
          } 
          contactWrap.add(new ContactsWrapper(contactId, display_name, phoneNumber,lookupKey,false,color_string)); 
         } 
//      map.put(contactId, new ArrayList<ContactsWrapper>(contactWrap)); 
         phones.close(); 
        } 
       } catch (Exception e) { 

        e.printStackTrace(); 
       } 
      } 
      controller.contactWrapper = contactWrap; 
     } 
     catch (Exception e) { 
      // TODO: handle exception 
      e.printStackTrace(); 
     } 
     } 

     return null; 
    } 

    @Override 
    protected void onPostExecute(Void result) { 
     // TODO Auto-generated method stub 
     super.onPostExecute(result); 
     constants.dismissDialog(); 

     adapter = new ContactsAdapter(cntx); 
     contactsList.setAdapter(adapter); 
    } 

} 

и это мой контакт класс обертка

public class ContactsWrapper { 

private long contactId; 
private String displayName,displayNumber,lookUp; 
public boolean checked = true; 
int color_string; 

public ContactsWrapper(long contactId, String displayName, String displayNumber, String lookUp, boolean checked,int color_string) { 
    // TODO Auto-generated constructor stub 
    this.contactId = contactId; 
    this.displayName = displayName; 
    this.displayNumber = displayNumber; 
    this.lookUp = lookUp; 
    this.checked = checked; 
    this.color_string =color_string; 
} 

public String getLookUp() { 
    return lookUp; 
} 

public int getColor_string() { 
    return color_string; 
} 

public boolean isChecked() { 
    return checked; 
} 

public long getContactId() { 
    return contactId; 
} 

public String getDisplayName() { 
    return displayName; 
} 

public String getDisplayNumber() { 
    return displayNumber; 
} 

public void setChecked(boolean checked) { 
    this.checked = checked; 
} 
}
