獲取拋出：IllegalArgumentException：列「數據1」不存在的Android

我試圖把姓名和電話號碼從通訊錄到我使用自定義的CursorAdapter的幫助下定製的ListView存在，但我收到以下錯誤獲取拋出：IllegalArgumentException：列「數據1」不存在的Android

這裏是我使用

主要活動代碼

守則3210

public class ManipulationActivity extends Activity { 


@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    setContentView(R.layout.contacts_list_layout); 

    Cursor cursor = getCursor(); 


    ListView contactList = (ListView)findViewById(R.id.contactList); 
    contactList.setAdapter(new ContactListCustomCursorAdapter(this, cursor)); //ContactListCustomCursorAdapter is a customized CursorAdapter. I have put the code below this class 

} 

    //Get Cursor pointing Contacts 
private Cursor getCursor() { 

    Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null); 
    while (cursor.moveToNext()) { 
     String contactId = cursor.getString(cursor.getColumnIndex( 
     ContactsContract.Contacts._ID)); 
     String hasPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)); 
     if (Boolean.parseBoolean(hasPhone)) { 
      // You know it has a number so now query it like this 
      Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId, null, null); 
      while (phones.moveToNext()) { 
      String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));     
      } 
     phones.close(); 
     } 
    } 
    cursor.close(); 
    return cursor; 
}  

}

ContactListCustomCursorAdapter代碼

public class ContactListCustomCursorAdapter extends CursorAdapter { 

private Context context; 
private Cursor cursor; 
private LayoutInflater inflater; 
private int username; 
private int phoneNumber; 

public ContactListCustomCursorAdapter(Context context, Cursor c) { 
    super(context, c); 
    this.context = context; 
    this.cursor = c; 
    inflater = LayoutInflater.from(context); 

    username = cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME); 
} 

@Override 
public void bindView(View view, Context context, Cursor cursor) { 
    TextView userName = (TextView)view.findViewById(R.id.userName); 
    userName.setText(cursor.getString(username)); 

    TextView phoneNumber = (TextView)view.findViewById(R.id.userNumber); 
    phoneNumber.setText(cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.NUMBER))); 
} 

@Override 
public View newView(Context context, Cursor cursor, ViewGroup parent) { 
    final View view = inflater.inflate(R.layout.custom_contact_list_item, parent, false); 

    return view; 
} 

}

我不想使用聯繫人選擇器。

首先，您傳遞給CursorAdapter的遊標已關閉。如果您將光標分配給適配器，則不應將其關閉，只需在onDestroy中爲您的活動調用changeCursor（null）即可。

其次，從我假設你要顯示所有聯繫人和聯繫電話號碼的清單的代碼，所以你getCursor方法應該是這樣的

private Cursor getCursor() { 

    Cursor cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null); 

    return cursor; 
}

和你bindView應該像

@Override 
public void bindView(View view, Context context, Cursor cursor) { 
    TextView userName = (TextView)view.findViewById(R.id.userName); 
    userName.setText(cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME))); 

    TextView phoneNumber = (TextView)view.findViewById(R.id.userNumber); 
    phoneNumber.setText(cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.NUMBER))); 
}

我沒有使用任何光標適配器，也沒有訪問任何接觸或電話號碼...所以你答案不起作用... – Nik

如果你不使用CursorAdapter，那麼你能解釋爲什麼你從CursorAdapter擴展嗎？ – iago

我已經解決了這個問題，確保數據庫在需要時打開，並在沒有時關閉。

我也有這個錯誤，花了幾個小時後，我得到了答案。還有CONSTANT COLUMN MISMATCH問題，'data1'或NUMBER是一個常數，屬於電話類。

ContactsContract。 聯繫人 .CONTENT_URI不提供數字，因爲您不得不提及使用查詢的投影，它會給出結果，在此幫助下您可以獲得._id，display_name。但是，如果你想從身份證號碼，那麼你必須要這樣的事情，

Cursor cursorPhone = getContentResolver().query(
       ContactsContract.CommonDataKinds.Phone.CONTENT_URI, 
       new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER}, 
       ContactsContract.Contacts._ID +" = " + item_ID, 
       null, 
       null);

謝謝
