在哪里放置android BindingAdapter方法？ [英] Where to place android BindingAdapter method?

问题描述

这必须是最基本的问题，但是经过一整天的阅读教程和文档后此处，我似乎无法理解将这些方法放在何处。没有指南提到放置此东西的地方，仅提及在静态方法上使用注释。什么静态方法？不管类如何，都有任何静态方法吗？什么是好习惯？我该创建一个CustomBinding类来托管所有这些静态方法吗？

This has to be the most basic of question but after a full day of reading tutorials and the documentation here I can't seem to understand where to put these methods. None of the guides mention where this thing is placed it just mentions to use the annotation on a static method. What static method? Any static method at all regardless of class? What is a good practice? do I create a CustomBinding class to host all these static methods?

只要我有该方法具有BindingAdapter批注并且第一个参数是View，它将起作用？

So long as I have the method has a BindingAdapter annotation and the first parameter is a View, it will work?

我假设如果第一个参数的类型为View，我可以将binding属性放在任何类型的视图上，它将触发该方法吗？因此，如果我有特定的视图说EditText，这是否意味着仅当在布局文件的EditText视图中找到该属性时才调用该方法？

I assume if the first parameter is of type View I can place the binding attribute on any type of views and it will trigger the method? So if I have specific view say EditText, does this mean the method is only called when the attribute is found in an EditText view in the layout file?

推荐答案

浏览Internet之后，我终于从其中一位开发人员身上找到了一些信息。我希望他们对文档的基础知识会更加清楚。

After navigating through the internet I've finally found some info from one of the developers themselves. I wish they would have been more clear on the basics in the documentation.

引用：

绑定适配器是任何类中的带注释方法用来做到这一点。通常，您会根据目标View类型将适配器组织为[-a]类。

这显然意味着在编译时，任何带有注解BindingAdapter的类都将生成BindingAdapter。

This obviously means that at compile time all methods in any class with the annotation BindingAdapter will generate the BindingAdapter.
