我只是在阅读我的表格，但我无法启动应用程序，因为它给了我这些错误：

这是连接到 dbclass 的代码。它调用 DBclass 中的 id 方法，然后关闭 db。

public int return_id_phone(Context contxt) {
    Database db = new Database(contxt);
    db.open();
    int id_phone = db.id(2);
    db.close();
    return id_phone;
}

这是要提取的代码。只返回一个数字，它很简单，我不知道它为什么会崩溃。它在下面的错误中说我没有关闭游标并且数据库也被锁定。

这是我的数据库类。昨天工作完美，今天不工作......

问题在于 onCreate() 您的日志最终只指向那里。请验证您在哪里扩展您的课程的代码：

extends SQLiteOpenHelper

如果您无法解决，请提供您创建表格的代码或您的日志指向的代码。因为它只是一个盲目的猜测，否则。
