MuSongzi_core

这是一个木松子的基本android 便捷搭建项目库。 使用到retrofit，okhttp fragment+viewmodel+business方式构建项目

app项目中有对应的使用例子

1）比如 com.musongzi.test.engine.ArrayEngine 快速构建列表

@CollecttionsEngine(isEnableReFresh = true, isEnableLoadMore = true, isEnableEventBus = true) class ArrayEngine : BaseMoreViewEngine<StringChooseBean, Array>() {

override fun getRemoteDataReal(page: Int): Observable<Array<StringChooseBean>> = getApi(Api::class.java).getArrayEngine(page)

override fun myAdapter() = adapter(AdapterStringBinding::class.java)

override fun transformDataToList(entity: Array<StringChooseBean>) = ArrayList<StringChooseBean>().let{
    it.addAll(entity)
    it
}

}

object ExtensionMethod{ .......... fun analysisCollectionsEngine(eClass: Class<*>): Fragment { val cAnnotation: CollecttionsEngine? = InjectionHelp.findAnnotation(eClass) val mCollectionsInfo = cAnnotation?.let { CollectionsViewModel.CollectionsInfo(it) } ?: CollectionsViewModel.CollectionsInfo() val bundle = Bundle(); ModelFragment.composeProvider(bundle, false) mCollectionsInfo.engineName = eClass.name bundle.putParcelable(ViewListPageFactory.INFO_KEY, mCollectionsInfo) val collectionsFragment = CollectionsViewFragment(); collectionsFragment.arguments = bundle return collectionsFragment } ......... }

2)快速构建速配器（RecycleView)

adapter(AdapterStringBinding::class.java)

class ExtensionMethod{ ................ /** * 返回一个adapter，不做任何数据绑定 * @receiver T * @param c Class * @return TypeSupportAdaper<[@kotlin.ParameterName] I> */ @JvmStatic fun <T : ISource, D : ViewDataBinding, I> T.adapter(c: Class) = adapter(c, null);

/**
 * 返回一个adapter,有一个onBindView
 * @receiver T
 * @param c Class<D>
 * @param run Function3<[@kotlin.ParameterName] D, [@kotlin.ParameterName] I, [@kotlin.ParameterName] Int, Unit>?
 * @return TypeSupportAdaper<[@kotlin.ParameterName] I>
 */
@JvmStatic
fun <T : ISource<I>, D : ViewDataBinding, I> T.adapter(
    c: Class<D>,
    run: ((dataBinding: D, item: I, postion: Int) -> Unit)?
) = TypeSupportAdaper.build(realData(), c, run
    ?: { _, _, _ -> })

................. }

3)使用Fragment(项目中有例子)

TestMainFragment->
class TestMainFragment : ModelFragment<TestViewModel, FragmentTestMainBinding>(), ITestClient {
......
}

TestViewModel->
class TestViewModel : BaseViewModel<ITestClient, TestBusiness>() {
......
}

ITestClient 回调函数（CallBack class use at View/activity/Fragment）->
interface ITestClient:IClient {
......
}

TestBusiness->
class TestBusiness : BaseLifeBusiness<TestViewModel>() {
......
}

TestMainFragment 默认持有一个泛型 TestViewModel
TestViewModel 持有当前的IHodlerActivity(Fragment) 和 ITestClient(刷新ui回调，)  ，并且持有一个基于泛型的业务实例 TestBusiness；
              他们的类注入在 IAttach.attachNow()此方法中注入到ViewModel(继承IAttach)：

            class MszViewModel<C:IClient,B:IBusiness>...{
                ......
                override fun attachNow(t: IHolderActivity?) {
                         if (isAttachNow()) {
                                return
                         }
                        super.attachNow(t)
                        client = t?.getClient() as? C
                        business = createBusiness()
                        (business as? BaseLifeBusiness<IAgent>)?.setAgentModel(this)
                        business.afterHandlerBusiness()
                    }

                ......

                protected fun createBusiness(): B = InjectionHelp.findGenericClass<B>(javaClass, 1).newInstance()

            }

简单事务管理 com.android.playmusic.l.viewmodel.imp.EventManger

使用方式调用  {interface.class}.event.{method}即可

任何注册接口和其父类方法都会被回调

例如：
--->
class MyApplication : MultiDexApplication(){
companion object {
    const val TAG = "MyApplication"
}

override fun onCreate() {
    super.onCreate()
//注册了接口
    registerEvent(IClient::class.java){
        object:IClient{
            override fun showDialog(msg: String?) {
                Log.i(TAG, "EventManger showDialog: $msg ${this@MyApplication}")
            }

            override fun disimissDialog() {

            }

            override fun disconnect() {

            }
        }
    }
}


-->

class TestMainFragment : ModelFragment<TestViewModel, FragmentTestMainBinding>(), ITestClient {

    override fun initData() {
    }

    override fun initEvent() {
        //使用接口回调
        ITestClient::class.java.event()?.showDialog("哈哈哈")
    }

    override fun showDialog(msg: String?) {
        super.showDialog(msg)
        Log.i(TAG, "EventManger showDialog: msg = $msg ")
    }


    override fun initView() {
        //注册了接口
        registerEvent(IClient::class.java) {
            this
        }

        Log.i(TAG, "initView: ${getMainViewModel()}")
        getMainViewModel()?.business?.checkBanner()
    }

    override fun showText(msg: String) {
        dataBinding.idMainContentTv.text = msg
    }
}

com.musongzi.core.base.manager.ActivityLifeManager

  fun <T> IHolderLifecycle.registerEvent(e: Class<T>, h: () -> T) {
        if (!e.isInterface) {
            Log.i("registerEvent", ": 1 ")
            return
        }
        Log.i("registerEvent", ": 2 ")
        getThisLifecycle()?.lifecycle?.addObserver(object : DefaultLifecycleObserver {
            override fun onCreate(owner: LifecycleOwner) {
                Log.i("registerEvent", ": 3 ")
                getEventManager().put(e, h)
            }

            override fun onDestroy(owner: LifecycleOwner) {
                Log.i("registerEvent", ": 4 ")
                getEventManager().remove(e, h.invoke())
            }

        })
    }

    fun <T> Class<T>.event(): T? {
        return if (!isInterface) {
            Log.i("eventFind", ": 1 必须是接口")
            null
        } else {
            Log.i("eventFind", ": 2 ")
            Proxy.newProxyInstance(classLoader, arrayOf(this)) { proxy, method, args ->
                Log.i("eventFind", ": 2 ")
                (getEventManager() as EventManger).asInvocationHandler().invoke(proxy, method, args)
            } as T
        }
    }
