在注册函数返回-1
上插入函数private String customerTable="create table customer (id integer primary key autoincrement, custname text not null,username text not null,password text notnull" +
"gender text ,birthdate text,jop text not null); ";
public long Registration (String name,String username,String password,String Gender,String birthdate,String jop)
{
Ecommerce=getWritableDatabase();
ContentValues row=new ContentValues();
//row.put("id",null);
row.put("custname", name);
row.put("username",username );
row.put("password", password);
row.put("gender", Gender);
row.put("birthdate", birthdate);
row.put("jop", jop);
return Ecommerce.insert("customer", null, row);
}
dbobject.Registration(customer_name, user_name, passwordfirst,customer_gender , cus_birthdate, customer_jop);

答案 0 :(得分：0)
在,之后，您的SQL查询（）中错过了not和null [{1}}和customerTable之间的空格} 。使用此查询并更改数据库的版本：
password text notnull然后将表格放入private String customerTable = "CREATE TABLE IF NOT EXISTS customer (" +
"id integer primary key autoincrement," +
"custname text not null," +
"username text not null," +
"password text not null," +
"gender text," +
"birthdate text," +
"jop text not null); ";
方法：
onUpgrade
