读取系统通讯录信息的时候出错：.IllegalStateException: Couldn't read row 0, col -1 from CursorWindow

.IllegalStateException: Couldn't read row 0, col -1 from CursorWindow.  Make sure the Cursor is initialized correctly before accessing data from it.

出错代码：

if (resultCode == Activity.RESULT_OK) {

      if (requestCode == REQUET_CODE) {
            ContentResolver resolver = getContentResolver();

            while (cursor.moveToNext()) {

                  String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
                  sb.append(name + ",");

                  int ifPhone = cursor.getInt(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
                  if (ifPhone > 0) {
                        int id = cursor.getInt(cursor.getColumnIndex(ContactsContract.Contacts._ID));
                        Cursor phone = resolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" + id, null, null);

                        while (phone.moveToNext()) {

                              String number = phone.getString(phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                              sb.append(number + ",");
                        }

                  }
                  text.setText(sb.toString());
            }


      }

=====================================================================

以上代码cursor，红色部分返回的是new String[]{ContactsContract.Contacts.DISPLAY_NAME}，这里应该返回全部，即null
