具有初始值的MutableLiveData [英] MutableLiveData with initial value

问题描述

如何使用初始值初始化 MutableLiveData ? 我正在寻找类似的东西:

How I can initialize MutableLiveData with initial value? I'm looking for something like:

val text = MutableLiveData<String>("initial value")

推荐答案

MutableLiveData已更新，现在有一个接受初始值的构造函数:)

MutableLiveData has been updated and now it has a constructor that accepts an initial value :)

据我所见，此版本开始提供了构造函数:

From what I can see, the constructor is available starting from this version:

implementation 'androidx.lifecycle:lifecycle-extensions:2.1.0-alpha01'

可惜他们还没有更新MediatorLiveData来反映这一点.

It's a shame they haven't updated MediatorLiveData to reflect that, though.

2.1.0终于稳定了，所以现在您实际上可以在文档中看到新的构造函数.

2.1.0 is finally stable, so now you can actually see the new constructor in the documentation.
