Question

我收到了"IllegalArgumentException: Version must be >= 1, was 0"错误：

super(context, name, factory, version, errorHandler);

在下面的课程中，我不确定为什么会发生这种情况（我只是想在我的sqlite数据库中添加用户名和密码 - 仅此而已）

IllegalArgumentException: Version must be >= 1, was 0

版本为1或大于1.在您的情况下为0.

此外，你需要为构造函数

使用正确的参数

new AddUser(context,name,factory,version,errorHandler);

您也可以使用以下内容。

 private static final String DATABASE_NAME = "RECORDS";
 private static final int DATABASE_VERSION = 1;
 // Have the above constants
 public AddUser(Context context) {
    super(context,DATABASE_NAME, null, DATABASE_VERSION);
    // TODO Auto-generated constructor stub
 }

使用的构造函数是

SQLiteOpenHelper(Context context, String name, SQLiteDatabase.CursorFactory factory, int version)

AddUser ad= new AddUser(ActivityName.this);

IllegalArgumentException：版本必须为＆gt; = 1，为0
