Android为textView设置setText的时候报错

一、我的代码如下：就是我textView设置值

if (list != null) {
    for (Student stu : list) {
        //如果一下子赋值的话是不正确的
        tv_name.setText(stu.getName());
        tv_sex.setText(stu.getSex());
        tv_age.setText(stu.getAge());

    }
}

报出错误：

具体解决方法：

if (list != null) {
    for (Student stu : list) {
        //如果一下子赋值的话是不正确的
        tv_name.setText(stu.getName()+"");
        tv_sex.setText(stu.getSex()+"");
        tv_age.setText(stu.getAge()+"");                        
    }
}
