一个Jetpack结合MVVM的快速开发框架

JetPackMvvm

• 基于MVVM模式集成谷歌官方推荐的JetPack组件库：LiveData、ViewModel、Lifecycle组件
• 使用kotlin语言，添加大量拓展函数，简化代码
• 加入Retorfit网络请求,协程，帮你简化各种操作，让你快速请求网络

演示Demo

已用该库重构了我之前的玩安卓项目，利用Navigation组件以单Activity+Fragment架构编写，优化了很多代码，对比之前的mvp项目，开发效率与舒适度要提高了不少，想看之前MVP的项目可以去 https://github.com/hegaojian/WanAndroid

1.如何使用

• 1.1 启用dataBinding 如果你需要用到dataBinding,请在主工程的build中加入，不用可以忽略这一步： 不想用dataBinding的继承BaseVmActivity，想用dataBinding的继承BaseVmDbActivity

  dataBinding{
        enabled = true
  }

• 1.2 依赖

dependencies {
  ...
  implementation 'me.hegj:JetpackMvvm:1.0.0'
}

2.登录示例（可以看demo，预先创建你的基类，并实现相关的方法）

• 2.1 LoginFragment继承基类传入相关泛型

class LoginFragment:BaseFragment<LoginRegisterViewModel, FragmentLoginBinding>() {

    override fun layoutId() = R.layout.fragment_login

    override fun initView() {
        login_sub.setOnClickListener {
            mViewModel.login()
        }
    }
    
    override fun createObserver() {
        //监听请求结果
        mViewModel.loginResult.observe(this, Observer { viewState ->
            parseState(viewState,{
                //登录成功 退出，，
            },{
                //登录失败
                showMessage(it.errorMsg)
            })
        })
    }
}

• 2.2 创建LoginViewModel继承BaseViewModel

class LoginViewModel:BaseViewModel() {
    
     //用户名
    var username = StringObservableField()
     //密码
    var password = StringObservableField()
    
    private val loginRpository:LoginRepository by lazy{ LoginRepository() }

    var loginResult = MutableLiveData<ViewState<UserInfo>>()

    fun login(){
        launchRequest({loginRpository.login(username.get(),password.get())},loginResult)
    }
}

• 3.3 创建数据仓库，不管数据是请求网络还是本地数据库拉取都在这里实现

class LoginRepository {

    //登录 自带协程
    suspend fun login(username: String, password: String): ApiResponse<UserInfo> {
        return NetworkApi.service.login(username, password)
    }
