Android联系人数据库给我一个例外

每当我尝试访问一个联系人的号码，我得到一个索引越界异常，任何人都可以告诉我，我在这里做错了什么。类的Android联系人数据库给我一个例外

成员

private String[] names; 
private String[] number;

在我的onCreate

ContentResolver cr = getContentResolver(); 
    Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null); 
    if (cur.getCount() > 0) 
    { 
     names = new String[cur.getCount()]; 
     number = new String[cur.getCount()]; 
     while (cur.moveToNext()) 
     { 
      String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID)); 
      String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); 
      names[cur.getPosition()] = name; 
      // number[cur.getPosition()] = name; 
      if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) { 
       Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ id,null, null); 
       try{ 
        number[cur.getPosition()] = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); 
       } 
       catch(Exception e) 
       { 
        Log.d("Exception", e.toString()); 
       } 
       phones.close(); 
      } 
     } 
    }

发布您的堆栈跟踪更清晰。 – 2011-10-17 13:01:13

发布你的logcat。让我们更清楚你的问题是什么。 – 2011-10-17 13:06:06

尝试增加

cur.moveToFirst();

while循环，并改变while(){}到do{} while()

编辑前：做同样的phones光标：您尝试{}语句前加上

phone.moveToFirst();

。
