Android为textView设置setText的时候报错的讲解方案

在对中TextView setText 覆值int 时报错，网上查下原因是setText整型表明是设值R.id.xxx，当然找不到。

解决方法是将int转化为string，用String.valueOf（xxx）

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()+"");            
  }
}

总结
