表创建好了，需要插入数据了，
我们下边演示3中方法插入数据

给主界面上添加一个按钮，点击按钮执行插入信息操作

方法一

String insertsql="insert into Student(name,age,address)values('feng',20,'xian')"; msqliteDatabase.execsql(insertsql);

方法二

String name="李四";
        int age =21;
        String address="北京";
//        String insertsql="insert into Student(name,'xian')"; String insertsql="insert into Student(name,address)values('"+name+"',"+age+",'"+address+"')"; msqliteDatabase.execsql(insertsql);

方法三

String insertsql="insert into Student(name,address)values(?,?,?)";
        Object[]objs=new Object[]{"刘",18,"a"};
        msqliteDatabase.execsql(insertsql,objs);
