一个快速以MVVM开始做项目的框架 MVVMQuick

xujiaji   2018-09-02 16:21   收藏

Version

MVVMQuick

旨在快速以MVVM开始开发项目,其内集成了dagger2、okhttp3、retrofit、BaseRecyclerViewAdapterHelper、lifecycle等常用的框架和一些工具。

将大部分逻辑抽象,希望可以通过几步简单的配置,即可省去重复逻辑的代码。

Note

目前还在测试开发中,有兴趣的朋友可以体验体验给给建议哦!如要运用到项目中请自行下载项目导入mvvm-quik模块,也可直接以该项目开始开发。

该项目参考:

  1. 学习MVVM的实际运用,并且结合Dagger
  2. todo-mvp-dagger
  3. todo-mvvm-live
  4. todo-mvvm-databinding
  5. mvvm-sample-app
  6. LearnMVVM

dependencies

implementation 'com.github.xujiaji:mvvm-quick:0.0.2'

Use

详细使用案例请参考:https://github.com/xujiaji/WanAndroid

1.定义ViewModel,继承MQViewModel

@Singleton
public class ProjectListViewModel extends MQViewModel
{
    ...
}

2.布局文件fragment_project_list以DataBinding的写法

<?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">
    <data>
        <variable
            name="projectListViewModel"
            type="com.xujiaji.learnmvvm.module.projectlist.ProjectListViewModel"/>
    </data>
    ...
</layout>

3.ui中的写法,将DataBinding和ViewModel作为泛型配置,MQFragment会自动为您自动实例化

@ActivityScoped
public class ProjectListFragment extends MQFragment<FragmentProjectListBinding, ProjectListViewModel>
{

    @Inject
    Lazy<ProjectAdapter> mAdapter;

    @Inject
    public ProjectListFragment() {}

    @Override
    public void onBinding(FragmentProjectListBinding binding)
    {
        ... 当Binding初始化后会调用
    }

    @Override
    public void onObserveViewModel(ProjectListViewModel viewModel)
    {
        ... 当ViewModel初始化后会调用(在Binding之后初始化)
    }
}

4.在ViewModelSubComponent中添加配置,提供ViewModel实例(实例提供通过Dagger实现)

@Subcomponent
public interface ViewModelSubComponent
{
    ...
    Lazy<ProjectListViewModel> projectListViewModel(); //add
}

5.在AppModuleprovidesViewModel方法中添加配置

    @Singleton
    @Provides
    static Map<Class<?>, Callable<Lazy<? extends ViewModel>>> providesViewModel(ViewModelSubComponent.Builder viewModelSubComponent)
    {
        ...
        creators.put(ProjectListViewModel.class, vmsc::projectListViewModel);//add
        return creators;
    }
