android - Function unresolved reference in main activity

问题描述

so I'll try to explain my problem this time without pasting you 400 lines of code.

I have a custom view that im using in my main activity (com.company.app.common.ui.view1), in my main activity it's imported properly as follow import com.company.app.common.ui.view1

Inside view1 i have a function defined in the constructor fun updateItems(items: List<Item>){}

Item is an object I have modeled properly and the function has no errors.

But when I try to call it in my main activity using view1.updateItems(items) I get an unresolved reference on updateItems.

the function is supposedly public by default if im not wrong, can anyone help? Thanks

解决方案

看起来您正在尝试在类而不是实例上调用该方法（获取实例的一种方法是通过构造函数创建它myView1 = view1(...)，然后您可以在其上调用该方法myView1.updateItems(items)

还有两点：

  • 无需发布所有代码，只需发布​​片段（仅与问题相关的代码），将不相关的代码替换为...并保留括号
  • 在我的回答中，我假设（根据你写的）view1应该是一个类/对象，最好将它的名字大写，这样它就不会与实例混淆
