implementation 'io.github.ayvytr:flow:0.1.0'
//可选：支持下拉刷新和上拉加载的BaseListActivity, BaseListFragment
implementation 'io.github.ayvytr:flow-list:0.1.0'- 修改initViewModel()，保证viewModel初始化成功（解决泛型信息缺失导致的getVmClass()异常问题）
- 增加IView.hideLoading()
- 修改BaseListActivity, BaseListFragment, adapter改名emptyAdapter，并改为protected
- 修改配置排除aar中的BuildConfig.class
- 增加BaseViewModel.performShowMessage()，解决launchFlow(), zipFlow()的参数onError默认实现**view.showMessage(it.stringId)**不适用网络请求错误的问题
- BaseFragment增加懒加载功能
- 修改gradle-maven-publish-plugin:0.20.0上传的包不是release的问题
- 增加BaseConfig.PAGE_SIZE为全局单页条目数
- 增加base-list模块，BaseListActivity，BaseListFragment方便下拉刷新和上拉加载
- 修改BaseViewModel.view 为protected
-
变更职能：增加[BaseViewModel]泛型[IView]，支持BaseActivity, BaseFragment重写：
- 方便接口回调写在BaseViewModel中，Activity,Fragment只做需要的ui回调
- 方便回传参数
-
增加BaseViewModel.zipFlow() ，可合并2个请求
-
修改BaseViewModel：launchFlow，**zipFlow()**参数onError顺序
-
ErrorObserver
- 使用stringId显示错误信息：方便做国际化
- 可全局自定义网络错误提示
- 全局设置请求失败重试次数
- 全局showLoading(boolean)
- 进行了封装，可决定接口调用时是否showLoading, 是否重试，是否可以repeatSameJob（是否允许同一接口同时多次请求）
- 只提供了onSuccess, onError的回调，且onError回调有默认处理。未提供onLoading, onComplete回调
分别继承BaseActivity/BaseFragment，BaseViewModel，IView，ui和ViewModel分工协作（需要Repository，DataBinding请自行添加）
interface WanAndroidView: IView {
fun showWanAndroidHome(wanAndroidHome: WanAndroidHome)
}
//需要泛型WanAndroidViewModel，实现WanAndroidView
class WanAndroidActivity: BaseActivity<WanAndroidViewModel>(), WanAndroidView {
override fun initView(savedInstanceState: Bundle?) {
super.initView(savedInstanceState)
setContentView(R.layout.activity_wan_android)
}
override fun initData(savedInstanceState: Bundle?) {
viewModel.getWanAndroidHome()
}
override fun showWanAndroidHome(wanAndroidHome: WanAndroidHome) {
tv_value.text = wanAndroidHome.toString()
}
}
//需要传递WanAndroidView
class WanAndroidViewModel: BaseViewModel<WanAndroidView>() {
val wanAndroidApi = ApiClient.getRetrofit(App.WAN_ANDROID_BASE_URL)
.create(WanAndroidApi::class.java)
fun getWanAndroidHome() {
launchFlow(
request = { wanAndroidApi.getHomeArticle() },
onSuccess = { view.showWanAndroidHome(it) },
onError = { view.showMessage(it.stringId) }
)
}
}如果BaseConfig.onShowLoading 使用了Dialog，请及时释放

override fun onCreate() {
super.onCreate()
// ...
initBaseConfig()
}

} else {
exception.stringId = R.string.network_timeout
}
}
is ConnectException -> {
exception.stringId =
if (networkAvailable) R.string.cannot_connect_server else R.string.network_not_available
}
is UnknownHostException -> {
exception.stringId =
if (networkAvailable) R.string.cannot_connect_server else R.string.network_not_available
}
is HttpException -> {
exception = NetworkException(e, R.string.cannot_connect_server, e.code())
e.message?.apply {
if(contains("404")) {
exception.stringId = R.string.http_404
}
}
}
else -> {
NetworkException(e, R.string.other_error)
}
}
exception
}
BaseConfig.onShowLoading = { context, isShow ->
val name = context.javaClass.name
if(isShow) {
var dialog = loadingMap[name]
if(dialog == null) {
dialog = LoadingDialog(context)
loadingMap[name] = dialog
}
dialog.show()
} else {
loadingMap[name]?.dismiss()
loadingMap.remove(name)
}
}
BaseConfig.onShowMessage = {context, message, rootView ->
Snackbar.make(rootView, message, Snackbar.LENGTH_LONG).show()
}
