AndroidX SwipeRefreshLayout with DataBinding
问题
我正试图使用AndroidX库实现下拉刷新功能：**androidx.swiperefreshlayout.widget.SwipeRefreshLayout**
由于我的应用正在使用Android Databinding，因此我想使用可观察字段来控制此小部件的状态。
在过去，我曾使用[AppCompat版本][1] - 但它已经被弃用了。
以前，我可以以以下方式访问字段：
<android.support.v4.widget.SwipeRefreshLayout
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:refreshing="@{viewModel.isLoading}">
...
// 这里是我的RecyclerView
</android.support.v4.widget.SwipeRefreshLayout>
但是，使用AndroidX的等效部分似乎不再起作用。
我是否漏掉了什么？或者是否有任何解决方案/变通方法可以实现此功能？
我的项目已经完全迁移到了AndroidX，没有错误或冲突的依赖项。

I'm trying to implement swipe to refresh functionality using AndroidX library: androidx.swiperefreshlayout.widget.SwipeRefreshLayout
My app is using Android Databinding therefore I'd like to use observable fields to control the state of this widget.
In the past I've used AppCompat one - it has as since been deprecated.
Before, I could access the fields in the following way:
<android.support.v4.widget.SwipeRefreshLayout
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:refreshing="@{viewModel.isLoading}">
...
// My RecyclerView here
</android.support.v4.widget.SwipeRefreshLayout>
But, this doesn't seem to work anymore - with the AndroidX equivalent.
Am I missing something? or is there any solution/workaround to achieve this?
My project has already been fully migrated to AndroidX, there are no errors or conflicting dependencies.

那被称为androidx.swiperefreshlayout.widget.SwipeRefreshLayout...
// https://mvnrepository.com/artifact/androidx.swiperefreshlayout/swiperefreshlayout
implementation "androidx.swiperefreshlayout:swiperefreshlayout:1.0.0"
例如：
<?xml version="1.0" encoding="utf-8"?>
<layout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools">
<data />
<androidx.appcompat.widget.LinearLayoutCompat
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<androidx.swiperefreshlayout.widget.SwipeRefreshLayout
android:id="@+id/swipe_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:refreshing="@{viewModel.isLoading}"
app:onRefreshListener="@{() -> viewModel.onRefresh()}">
...
</androidx.swiperefreshlayout.widget.SwipeRefreshLayout>
</androidx.appcompat.widget.LinearLayoutCompat>
</layout>
然后，在onRefresh()中，可以从数据绑定中获取RecyclerView.Adapter。
英文:
That's called androidx.swiperefreshlayout.widget.SwipeRefreshLayout ...
// https://mvnrepository.com/artifact/androidx.swiperefreshlayout/swiperefreshlayout
implementation "androidx.swiperefreshlayout:swiperefreshlayout:1.0.0"
For example:
<?xml version="1.0" encoding="utf-8"?>
<layout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools">
<data />
<androidx.appcompat.widget.LinearLayoutCompat
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<androidx.swiperefreshlayout.widget.SwipeRefreshLayout
android:id="@+id/swipe_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:refreshing="@{viewModel.isLoading}"
app:onRefreshListener="@{() -> viewModel.onRefresh()}">
...
</androidx.swiperefreshlayout.widget.SwipeRefreshLayout>
</androidx.appcompat.widget.LinearLayoutCompat>
</layout>
Then onRefresh(), one can get the RecyclerView.Adapter from the data-binding.

你可以为此创建自己的BindingAdapter。
