Не удалось прочитать строку 0, col 9 из CursorWindow

Question

Я получаю ошибку Не удалось прочитать строку 0, col 9 из CursorWindow. Перед доступом к данным убедитесь, что курсор инициализирован правильно. Два других человека могут запускать код без ошибок, но на моей машине он его выдает. Я очень смущен. Вот код, который имеет дело с SQLite: Заранее спасибо, извините, есть много кода

Answer 1

это потому, что вы пытаетесь получить данные, прежде чем проверять их это доступных данных или нет.

if (cursor.moveToFirst()) { 
    do { 
     // your content 
    } while (cursor.moveToNext()); 
} 

Изменить этот блок для

while (cursor.moveToNext()) { 
     // your content 
} 

Как это.

Несомненно, это поможет вам.
