但凡用过鸿蒙原生弹窗的小伙伴,就能体会到它们是有多么的难用和奇葩,什么AlertDialog,CustomDialog,SubWindow,bindXxx,只要大家用心去体验,就能发现他们有很多离谱的设计和限制,时常就是一边用,一边骂骂咧咧的吐槽
实属无奈,就把鸿蒙版的SmartDialog写出来了
flutter的自带的dialog是可以应对日常场景,例如:简单的打开一个弹窗,非UI模块使用,跨页面交互之类;flutter_smart_dialog 是补齐了大多数的业务场景和一些强大的特殊能力,flutter_smart_dialog 对于flutter而言,日常场景是锦上添花,特殊场景是雪中送炭
但是 ohos_smart_dialog 对于鸿蒙而言,日常场景就是雪中送炭!单单一个使用方式而言,就是吊打鸿蒙的CustomDialog,CustomDialog的各种限制和使用方式,我不想再去提及和吐槽了
有时候,简洁的使用,才是最大的魅力
鸿蒙版的SmartDialog有什么优势?
目前 flutter_smart_dialog 的代码量16w+,完整复刻其功能,工作量非常大,目前只能逐步实现一些基础能力,由于鸿蒙api的设计和相关限制,用法和相关初始化都有一定程度的妥协
鸿蒙版本的SmartDialog,功能会逐步和 flutter_smart_dialog 对齐(长期),api会尽量保持一致
// dialog
SmartDialog.show({
builder: dialogArgs,
builderArgs: Math.random(),
})
@Builder
function dialogArgs(args: number) {
Text(args.toString()).padding(50).backgroundColor(Color.White)
}
// loading
SmartDialog.showLoading()
ohpm install ohos_smart_dialog
下述的配置项,可能会有一点多,但,这也是为了极致的体验;同时也是无奈之举,相关配置难以在内部去闭环处理,只能在外部去配置
这些配置,只需要配置一次,后续无需关心
完成下述的配置后,你将可以在任何地方使用弹窗,没有任何限制
@Entry
@Component
struct Index {
navPathStack: NavPathStack = new NavPathStack()
build() {
Stack() {
// here: monitor router
Navigation(OhosSmartDialog.registerRouter(this.navPathStack)) {
MainPage()
}
.mode(NavigationMode.Stack)
.hideTitleBar(true)
.navDestination(pageMap)
// here
OhosSmartDialog()
}.height('100%').width('100%')
}
}
别问我为啥返回事件的监听,处理的这么不优雅,鸿蒙里面没找全局返回事件监听,我也没辙。。。
// Entry页面处理
@Entry
@Component
struct Index {
onBackPress(): boolean | void {
return OhosSmartDialog.onBackPressed()()
}
}
// 路由子页面
struct JumpPage {
build() {
NavDestination() {
// ....
}
.onBackPressed(OhosSmartDialog.onBackPressed())
}
}
// Entry页面处理
@Entry
@Component
struct Index {
onBackPress(): boolean | void {
return OhosSmartDialog.onBackPressed(this.onCustomBackPress)()
}
onCustomBackPress(): boolean {
return false
}
}
// 路由子页面
@Component
struct JumpPage {
build() {
NavDestination() {
// ...
}
.onBackPressed(OhosSmartDialog.onBackPressed(this.onCustomBackPress))
}
onCustomBackPress(): boolean {
return false
}
}
如果出现该情况,请参照下述解决方案
OhosSmartDialog.observe
export default class YourNavigatorObserver implements NavigationInterception {
willShow?: InterceptionShowCallback = (from, to, operation, isAnimated) => {
OhosSmartDialog.observe.willShow?.(from, to, operation, isAnimated)
// ...
}
didShow?: InterceptionShowCallback = (from, to, operation, isAnimated) => {
OhosSmartDialog.observe.didShow?.(from, to, operation, isAnimated)
// ...
}
}
export default class EntryAbility extends UIAbility {
onConfigurationUpdate(newConfig: Configuration): void {
OhosSmartDialog.onConfigurationUpdate(newConfig)
}
}
function init() {
// show
SmartDialog.config.custom.maskColor = "#75000000"
SmartDialog.config.custom.alignment = Alignment.Center
// showAttach
SmartDialog.config.attach.attachAlignmentType = SmartAttachAlignmentType.center
}
// 检查当前是否有CustomDialog,AttachDialog或LoadingDialog处于打开状态
let isExist = SmartDialog.checkExist()
// 检查当前是否有AttachDialog处于打开状态
let isExist = SmartDialog.checkExist({ dialogTypes: [SmartAllDialogType.attach] })
// 检查当前是否有tag为“xxx”的dialog处于打开状态
let isExist = SmartDialog.checkExist({ tag: "xxx" })
SmartDialog.showLoading({ builder: customLoading })
但是对于大家来说,肯定是想用 SmartDialog.showLoading()
这种简单写法,所以支持自定义全局默认样式

对于Loading而言,应该有几个比较明显的特性
从上面列举几个特性而言,loading是一个非常特殊的dialog,所以需要针对其特性,进行定制化的实现
当然了,内部已经屏蔽了细节,在使用上,和dialog的使用没什么区别
SmartDialog.showLoading()
export function loadingCustom() {
SmartDialog.showLoading({
builder: customLoading,
})
}
@Builder
export function customLoading() {
Column({ space: 5 }) {
Text("again open loading").fontSize(16).fontColor(Color.White)
LoadingProgress().width(80).height(80).color(Color.White)
}
.padding(20)
.borderRadius(12)
.onClick(() => loadingCustom())
.backgroundColor(randomColor())
}
鸿蒙版的SmartDialog,相信会对开发鸿蒙的小伙伴们有一些帮助.
现在就业环境真是让人头皮发麻,现在的各种技术群里,看到好多人公司各种拖欠工资,各种失业半年的情况
淦,不知道还能写多长时间代码!
