[](https://jitpack.io/#HeartHappy/viewmodelautomation) ## 该框架不再维护，请迁移至ViewModelAutomationX版本，采用KSP+Retroift架构 ## 自动生成ViewModel、网络请求框架 #### 一、项目地址：[Github](https://github.com/HeartHappy/ViewModelAutomation) - 框架优势：通过提供的注解自动生成ViewModel层的LiveData、StateFlow，以及网络请求。节省您大量的开发时间 - 交流方式： - 1、欢迎使用issues提建议或bug - 2、欢迎Star以兹鼓励 #### 二、集成 - 如果你的项目 Gradle 配置是在 `7.0 以下`，需要在 `build.gradle` 文件中加入(默认jdk1.8) ```groovy allprojects { repositories { //远程仓库：https://jitpack.io maven { url 'https://jitpack.io' } } } ``` - 如果你的 Gradle 配置是 `7.0 及以上`，则需要在 `settings.gradle` 文件中加入（默认jdk11） ```groovy dependencyResolutionManagement { repositories { //远程仓库：https://jitpack.io maven { url 'https://jitpack.io' } } } ``` - 在项目 app 模块下的 build.gradle 文件中加入远程依赖和kapt插件 ```groovy plugins { id 'kotlin-kapt' } dependencies { //ktor网络框架 implementation("io.ktor:ktor-client-core:1.6.0") //ktor扩展库 implementation("com.github.hearthappy.viewmodelautomation:ktor-expand:2.0.6") //注解库 compileOnly("com.github.hearthappy.viewmodelautomation:annotations:2.0.6") //处理注解自动生成库 kapt("com.github.hearthappy.viewmodelautomation:processor:2.0.6") } ``` #### 三、使用示例（或参考Demo）： ##### 1、使用@BindStateFlow或@BindLiveData生成命名函数并绑定StateFlow/LiveData属性 ```kotlin @AndroidViewModel @BindLiveData("getImages", ReImages::class, ResImages::class) class MainActivity : AppCompatActivity() { override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) } } ``` ##### 2、使用@Request注解生成网络请求（GET示例。其他类型参见，标题四：“HTTP请求”） ```kotlin /** * GET:获取图片 * @property page Int * @property size Int * @constructor */ @Request(urlString = "/getImages") data class ReImages(val page: Int, val size: Int) ``` ##### 3、使用ViewModel ```kotlin //Activity中添加 private val viewModel by viewModels<MainViewModel>() //监听 lifecycleScope.launchWhenCreated { viewModel.getImagesStateFlow.collect { when (it) { is RequestState.LOADING-> progress.show() is RequestState.SUCCEED -> tvResult.showSucceedMsg(it.body.toString()) is RequestState.FAILED -> tvResult.showFailedMsg(it) is RequestState.Throwable -> tvResult.showThrowableMsg(it) else -> Unit } } } ``` ##### 4、生成MainViewModel ###### （1）完成步骤2基础上，点击AndroidStudio->Build->Make Project，编译生成MainViewModel类 ###### （2）ViewModel生成路径：build/generated/source/kaptKotlin/debug/com/hearthappy/compiler/viewmodel/MainViewModel.kt #### 四、[HTTP请求](https://github.com/HeartHappy/ViewModelAutomation/blob/2.0.3/HTTP.md) #### 五、[注解简介](https://github.com/HeartHappy/ViewModelAutomation/blob/2.0.3/Annotation.md)
