识别用于多个活动的视图

[英]Identify a view used in multiple activities

I have a spinner that i use over several activities. 我有一个用于多个活动的微调器。 In one of them, I have to modify one of the parameters of the spinner. 在其中之一中,我必须修改微调器的参数之一。 How could i identify from the spinner itself (without passing any extra parameter) the activities where the spinner will be inflated? 我如何从微调框本身识别(不传递任何额外的参数)微调框将膨胀的活动?

Depends a bit on your app - but I see 2 approaches for now: 取决于您的应用程序-但我现在看到2种方法:

1 You could add a tag to the spinner 1您可以将标签添加到微调器

2 You check the context of the spinner 2您检查微调器的上下文
