SQLite3 设置主键自增无效

[coderqianlq]

实体类定义如下：

public class People {
    public int ID = -1;
    public String Name;
    public int Age;
    public double Height;
}

sql语句如下：

db.execSQL("create table if not exists " + DB_TABLE + " (ID integer " +
                " primary key autoincrement, " +
                " name varchar(20)," +
                " age integer," +
                " height double)");

执行db.insert(DB_TABLE, null, newValues);主键始终为-1，不自增。
