Android 无法在注册表中注册（未插入表）

错误清楚地表明：

表igate1没有名为password的列。

您的创建查询是：

private static final String DATABASE_TABLE_CREATE = "CREATE TABLE "
                + DATABASE_TABLE_NAME
                + "("
                + "_id INTEGER PRIMARY KEY AUTOINCREMENT,"
                + "firstname TEXT NOT NULL, lastname TEXT NOT NULL, gender TEXT NOT NULL,email TEXT NOT NULL, phoneno TEXT NOT NULL, address TEXT NOT NULL,bloodgroup TEXT NOT NULL, dob TEXT NOT NULL,father TEXT NOT NULL, mother TEXT NOT NULL, username TEXT NOT NULL, pass TEXT NOT NULL, cpass TEXT NOT NULL );";

还有

pass

和

cpass

字段，而不是

password

改变这个，你就完了

---

希望这能有所帮助。

logcat中的错误非常明显：

SQLiteException:表igate1没有名为password的列

您将该字段声明为：

公共静态最终字符串键\u PASS=“PASS”

但您正试图在“密码”列中插入：

值。put（“密码”，password）

为什么不使用DBHelper中声明的列名常量？

创建表字符串：

private static final String DATABASE_TABLE_CREATE = "CREATE TABLE "
                + DATABASE_TABLE_NAME
                + "("
                + "_id INTEGER PRIMARY KEY AUTOINCREMENT,"
                + "firstname TEXT NOT NULL, lastname TEXT NOT NULL, gender TEXT NOT NULL,email TEXT NOT NULL, phoneno TEXT NOT NULL, address TEXT NOT NULL,bloodgroup TEXT NOT NULL, dob TEXT NOT NULL,father TEXT NOT NULL, mother TEXT NOT NULL, username TEXT NOT NULL, pass TEXT NOT NULL, cpass TEXT NOT NULL );";

如果签出创建表字符串，则该字段称为

pass

。但是，当您插入值时，您使用的是“密码”作为密钥。您需要确保在使用ContentValues向数据库中插入值时，键与表的列名相同

values.put("lastname", lname);
values.put("gender", Gen);
...
values.put("password", address);

此外，如果多次使用同一键输入值，则只保存最后一个值。因此，请确保不要使用同一个密钥两次

---

在您的情况下，您使用了两次

“password”

和

“phoneno”

键。尽管这不会以崩溃的形式出现，但它可能会在以后引起关注

很可能您只是混淆了此行中的表列名

values.put("password", address);

可能是这样的

values.put("address", address);

检查其他列名。您还有其他打字错误（“密码”而不是“通行证”等）。 此外，列名还有字符串常量。使用它来防止此类错误

   private static final String DATABASE_TABLE_CREATE = "CREATE TABLE "
                    + DATABASE_TABLE_NAME
                    + "("
                    + KEY_ROWID + "INTEGER PRIMARY KEY AUTOINCREMENT,"
                    + KEY_FNAME  +"TEXT NOT NULL, ....

及

---

嘿，你的代码有两个变化

第一个是您正在使用

String selection = "username=? AND password=?"; // change to pass

第二：字段名称错误：

ContentValues values = new ContentValues();
values.put("firstname", fname);
values.put("lastname", lname);
values.put("gender", Gen);
values.put("email", email);
values.put("username", phoneno);
values.put("password", address);
values.put("phoneno", bloodgroup);
values.put("lastname", dob);
values.put("gender", father);
values.put("email", mother);
values.put("username", username);
values.put("password", password);
values.put("phoneno", cpassword); 

那里的用户有效字段。

这可能有助于您解决错误。

您的问题是Registration.java-->addEntry（）方法之间存在差异 和DB助手。如果答案回答了您的问题，请投票或标记答案
