片段和onCreate()中的setArguments() [英] setArguments() in Fragment and onCreate()

问题描述

如果我创建一个新的 Fragment ，然后为其设置参数，我可以依靠那些始终在 onCreate()中可用的参数>片段?如果是，他们将如何做?如果不是，我该如何沟通，如果他们不希望我们编写新的构造函数?

If I create a new Fragment and then I set arguments to it can I rely on those arguments always being available for me in the onCreate() of the Fragment? If yes, how do they do it? If not how I'am I supposed to communicate if they don't want us to write new constructors?

推荐答案

是的，您的参数在onCreate方法中可用.请检查此响应，以了解如何将参数传递给片段:如何将一些数据传输到另一个片段?

Yes, your arguments are avaialble in onCreate method. Please check it out this response in order to see how to pass arguments to fragments: How to transfer some data to another Fragment?

与片段通信的另一种方法是通过您的活动正在实现的接口，然后在onAttach方法中将其作为对片段的引用进行传递.更多信息: https://developer.android.com/training/basics/fragments/communication

Another way to communicate with the fragment is via a interface that your activity is implementing and you pass it as a reference to your fragment, in onAttach method. More info: https://developer.android.com/training/basics/fragments/communicating
