AndroidMviFrame 是一个Android简单易用的项目框架
文档下面会对框架中所使用的一些核心技术进行阐述。该框架作为技术积累的产物,会一直更新维护,如果有技术方面的谈论或者框架中的错误点,可以在 GitHub 上提 Issues,我会及时进行回应并进行修复。
希望这个框架项目能给大家带来帮助,喜欢可以Start🌟。
是依赖所有组件的壳,该工程中只要MainActivity相关信息。
项目的基础公共模块,存放着各种基类封装、对远程库的依赖、以及工具类、三方库封装,该组件是和项目业务无关的,和项目业务相关的公共部分需要放在 lib_common 中。
项目的业务公共模块,这里面存放着项目里各个业务组件的公共部分。
项目使用技术栈为:
组件化是指解耦复杂系统时,将多个功能模板拆分、重组的过程。在Android工程表现上就是把app按照其业务的不同,划分为不同的Module。
组件化架构的目的就是让每个业务模块变得相对独立,各个组件在组件模式下可以独立开发调试,集成模式下又可以集成到“app壳工程”中,从而得到一个具有完整功能的APP。
配置如下 gradle.properties
当设置成true时,单个module可以运行
singleModule=false
当你生成一个新的Module的时候,需要做以下配置,这样才可以保证你的Module当组件运行的时候,万无一失。
第一步:
`
if (!singleModule.toBoolean()) {
apply plugin: 'com.android.library'
} else {
apply plugin: 'com.android.application'
}
apply from: '../dependencies.gradle'
android {
sourceSets {
main {
if (!singleModule.toBoolean()) {
//如果是library,则编译manifest下AndroidManifest.xml
manifest.srcFile 'src/main/manifest/AndroidManifest.xml'
} else {
//如果是application,则编译主目录下AndroidManifest.xml
manifest.srcFile 'src/main/AndroidManifest.xml'
}
}
}
defaultConfig {
if (singleModule.toBoolean()) {
applicationId rootProject.applicationId
}
kapt {
arguments {
arg("AROUTER_MODULE_NAME", project.getName())
}
}
javaCompileOptions {
annotationProcessorOptions {
arguments = [AROUTER_MODULE_NAME: project.getName()]
}
}
ndk {
abiFilters rootProject.ext.abiFilters
}
}
buildTypes {
debug {}
stagdebug {
consumerProguardFiles 'proguard-rules.pro'
}
stagrelease {
consumerProguardFiles 'proguard-rules.pro'
}
release {
consumerProguardFiles 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: "libs", include: ["*.jar", '*.aar'])
implementation project(':libs:lib_common')
annotationProcessor 'com.alibaba:arouter-compiler:1.5.2'
}
`
复制以上内容,覆盖module下的build.gradle文件
第二步:
在module的main文件夹下边创建manifest文件夹,在此文件夹下创建AndroidManifest.xml
至此组件化就配置完成了。
-
Model层: 它是一个 ViewModel,其中执行不同的同步或异步任务。它接受 UserIntents 作为输入并产生一个或多个连续状态作为输出。
-
View层: 视图只是处理它从 ViewModel 接收到的不可变状态以更新 UI。它还允许将用户操作传输到 ViewModel 以完成定义的任务。
-
Intent层: 表示用户与 UI 交互时的意图。例如,单击按钮刷新数据列表将被建模为 Intent。为了避免与 Android 框架 Intent 混淆,我们将在本文的其余部分将其称为 UserIntent。。
关于MVI base层的封装这里不在过多叙述,感兴趣的可以直接clone项目研究,这里我们就是说如何使用。
这里我们以module_home为例:
第一步:在项目里添加service文件夹,创建HomeService接口类
``
interface HomeService {
@POST(ComServerApi.API_BANNER)
suspend fun getBanner(@Body requestBody: RequestBody): BaseData<List<WanBean>>
@GET(ComServerApi.API_COIN_RANK)
suspend fun getRankList(): BaseData<RankBean>
}
第二步:封装Home接口网络层
``
class HomeRepo : BaseRepository() {
private val service = RetrofitUtil.getService(HomeService::class.java)
suspend fun requestWanData(drinkId: String): BaseData<List<WanBean>> {
val requestBody = jsonRequest()
.p("drinkId", drinkId)
.body()
return executeRequest { service.getBanner(requestBody) }
}
suspend fun requestRankData(): BaseData<RankBean> {
return executeRequest { service.getRankList() }
}
}
第三步:添加HomeMviState状态
``
data class MviState(val bannerUiState: BannerUiState, val detailUiState: DetailUiState?) : IUiState
sealed class BannerUiState {
object INIT : BannerUiState()
data class SUCCESS(val models: List<WanBean>) : BannerUiState()
}
data class MviSingleUiState(val message: String) : ISingleUiState
sealed class DetailUiState {
object INIT : DetailUiState()
data class SUCCESS(val detail: RankBean) : DetailUiState()
}
第四步:封装Model调用网络接口
``
class HomeMviModel : BaseMviModel<MviState, MviSingleUiState>() {
private val mLoginRepo = HomeRepo()
fun initData(bundle: Bundle?) {
}
override fun initUiState(): MviState {
return MviState(BannerUiState.INIT, DetailUiState.INIT)
}
/**
* 获取banner信息
*/
fun loadBannerData() {
requestDataWithFlow(
showLoading = true,
request = { mLoginRepo.requestWanData("12345") },
successCallback = { data ->
sendUiState {
copy(bannerUiState = BannerUiState.SUCCESS(data))
}
},
failCallback = {}
)
}
//请求List数据
fun loadDetailData() {
requestDataWithFlow(
showLoading = false,
request = { mLoginRepo.requestRankData() },
successCallback = { data ->
sendUiState {
copy(detailUiState = DetailUiState.SUCCESS(data))
}
},
failCallback = {}
)
}
}
第五步:Activity/Fragment初始化mViewModel
`
private val mViewModel: HomeMviModel by viewModels()
调用接口
mViewModel.loadDetailData()
获取后台数据
mViewModel.uiStateFlow.flowWithLifecycle2(
this, Lifecycle.State.STARTED,
prop1 = MviState::detailUiState
) { state ->
when (state) {
is DetailUiState.INIT -> {}
is DetailUiState.SUCCESS -> {
val list = state.detail.datas
mBinding.tvShowUser1.text = "显示Banner数据2:${Gson().toJson(list)}"
}
}
}
