ViewModelProviders 在 1.1.0 中已弃用
[英]ViewModelProviders is deprecated in 1.1.0
问题描述
Looking at the Google docs for ViewModel , they show the below sample code on how to get a ViewModel :
查看ViewModel的Google 文档，他们展示了以下关于如何获取ViewModel的示例代码：
val model = ViewModelProviders.of(this).get(MyViewModel::class.java)
When using the latest dependency android.arch.lifecycle:extensions:1.1.1 there is no such class ViewModelProviders .当使用最新的依赖android.arch.lifecycle:extensions:1.1.1时没有这样的 class ViewModelProviders 。
Going to the documentation for ViewModelProviders , I saw a comment saying:转到ViewModelProviders的文档，我看到一条评论说：
This class was deprecated in API level 1.1.0.
The problem is, when trying to use ViewModelProvider.AndroidViewModelFactory , cannot find an equivalent of method to get the instance of the ViewModel .问题是，当尝试使用ViewModelProvider.AndroidViewModelFactory时，找不到等效of方法来获取ViewModel的实例。
What i tried doing:我尝试做的事情：
ViewModelProvider.AndroidViewModelFactory.getInstance(application).create(PlayerViewHolder::class.java)
Hence the name of the method create , I get a new instance of the ViewModel every-time I call it, which is not what I am after.因此方法的名称create ，我每次调用它时都会得到一个 ViewModel 的新实例，这不是我所追求的。
Any ideas what is the replacement of deprecated code above?有什么想法可以替换上面不推荐使用的代码吗？

There is nothing about the get method that is deprecated . deprecated get方法。 If you follow the Android Developer instructions then you should get the VM like this. 如果您遵循Android Developer说明，那么您应该像这样获得VM 。
public class MyActivity extends AppCompatActivity {
public void onCreate(Bundle savedInstanceState) {
// Create a ViewModel the first time the system calls an activity's onCreate() method.
// Re-created activities receive the same MyViewModel instance created by the first activity.
MyViewModel model = ViewModelProviders.of(this).get(MyViewModel.class);
model.getUsers().observe(this, users -> {
// update UI
});
}
}
Here is the instructions on how to use ViewModels Here is the instructions on how to set up your project with the correct dependencies 以下是有关如何使用ViewModels的说明以下是有关如何使用正确的依赖项设置项目的说明

Looking at the Google docs for ViewModel , they show the below sample code on how to get a ViewModel :查看ViewModel的Google 文档，它们显示了有关如何获取ViewModel的以下示例代码：
val model = ViewModelProviders.of(this).get(MyViewModel::class.java)
When using the latest dependency android.arch.lifecycle:extensions:1.1.1 there is no such class ViewModelProviders .当使用最新的依赖android.arch.lifecycle:extensions:1.1.1 ，没有这样的类ViewModelProviders 。
Going to the documentation for ViewModelProviders , I saw a comment saying:转到ViewModelProviders的文档，我看到一条评论说：
This class was deprecated in API level 1.1.0.
The problem is, when trying to use ViewModelProvider.AndroidViewModelFactory , cannot find an equivalent of method to get the instance of the ViewModel .问题是，当尝试使用ViewModelProvider.AndroidViewModelFactory ，找不到等效of方法来获取ViewModel的实例。
What i tried doing:我尝试做的事情：
ViewModelProvider.AndroidViewModelFactory.getInstance(application).create(PlayerViewHolder::class.java)
Hence the name of the method create , I get a new instance of the ViewModel every-time I call it, which is not what I am after.因此，方法create的名称，每次我调用它时都会得到一个新的 ViewModel 实例，这不是我所追求的。
Any ideas what is the replacement of deprecated code above?任何想法替换上面已弃用的代码是什么？

You can use something like this:你可以使用这样的东西：
private val sharedViewModel: SharedViewModel by viewModels(ownerProducer = { requireActivity() })
ownerProducer = { requireActivity() } // This is only required if you want to share same view model among different fragments.

I am using Library of Lifecycle 2.3.1 and add below dependency in build.gradle (Module-level)我正在使用生命周期库 2.3.1 并在build.gradle （模块级）中添加以下依赖项
implementation 'androidx.lifecycle:lifecycle-viewmodel-ktx:2.3.1'
implementation 'androidx.lifecycle:lifecycle-livedata-ktx:2.3.1'
implementation 'androidx.lifecycle:lifecycle-runtime-ktx:2.3.1'
implementation 'androidx.lifecycle:lifecycle-extensions-ktx:2.2.0'
implementation 'androidx.activity:activity-ktx:1.4.0'
implementation 'androidx.fragment:fragment-ktx:1.3.6'
Declare viewModels() in your Kotlin code as per below:在您的Kotlin代码中声明viewModels()如下：
import androidx.fragment.app.viewModels
private val cartViewModel: CartViewModel by viewModels()

Update: July 20 2022更新：2022 年 7 月 20 日
private lateinit var binding: FragmentHomeBinding private lateinit var homeMvvM : HomeViewModel私有lateinit var绑定：FragmentHomeBinding私有lateinit var homeMvvM：HomeViewModel
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
homeMvvM = ViewModelProvider(this)[HomeViewModel::class.java]
this works for me.这对我有用。

//Activity ktx
implementation 'androidx.activity:activity-ktx:1.5.1'
//Fragment ktx
implementation 'androidx.fragment:fragment-ktx:1.5.1'
Simplest way of creating view models:创建视图模型的最简单方法：
class MyViewModel() : ViewModel() {
}
class SomeActivity:AppCompatActivity(){
private val viewModel: MyViewModel by viewModels()
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_some)
}
}
View Model With Constructor Arguments:使用构造函数 Arguments 查看 Model：
class MyViewModel(list:List<String>) : ViewModel() {
class Factory(list:List<String>) : ViewModelProvider.Factory {
@Suppress("unchecked_cast")
override fun <T : ViewModel> create(modelClass: Class<T>): T {
return MyViewModel(list) as T
}
}
}
class SomeActivity:AppCompatActivity(){
private val viewModel: MyViewModel by viewModels(){
MyViewModel.Factory(listOf<String>("a"))}
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
}
}

Try adding this code in your build.gradle module level尝试在您的 build.gradle 模块级别添加此代码
android {
kotlinOptions {
freeCompilerArgs += [
'-Xjvm-default=enable'
]
}
}
