返回自定义对象列表时，RxJava 会突出显示错误但会编译 [英] When returning a List of custom Objects RxJava highlights an error but compiles
问题描述
我正在进行 RxJava 调用，我订阅的最终结果是预订列表.
I'm making an RxJava call and the end result I subscribe to is a List of Booking.
代码工作正常，但我得到了这个烦人的亮点:
The code works fine but I get this annoying highlight:
演员表在这里不起作用，因为我无法将 List 转换为 List .
A cast doesn't work here because I can't cast List <Booking> to List <Object>.
好吧，你可能会说我应该用 lambda 表达式替换它，但是在 call() 方法中，我需要调用一个接受 List 的方法代码>作为参数:
Ok, you might say I should just replace it with a lambda expression, but in the call() method I need to call a method that takes List <Booking> as a parameter:
如何避免在任何这些情况下突出显示?
How can I avoid highlighting in any of these cases?
推荐答案
您可以向泛型方法添加显式类型，例如
You can add an explicit type to the generic methods, such as <Booking>flatMap. Sometimes Java 8 type inference doesn't work well.
