强大的SmartDialog
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
但凡用过鸿蒙原生弹窗,就能体会到有多么难用和奇葩,我就不吐槽了!!!实在受不了,就把鸿蒙版的SmartDialog写出来了,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。
// 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
配置完下述的初始化操作后,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() {
Navigation(this.navPathStack) {
MainPage()
}
.mode(NavigationMode.Stack)
.hideTitleBar(true)
.navDestination(pageMap)
// here dialog init
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
}
}
export default class EntryAbility extends UIAbility {
onConfigurationUpdate(newConfig: Configuration): void {
OhosSmartDialog.onConfigurationUpdate(newConfig)
}
}
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,估支持自定义全局默认样式
@Entry
@Component

OhosSmartDialog({
// custom global loading
loadingBuilder: customLoading,

}
}
@Builder
export function customLoading(args: ESObject) {
LoadingProgress().width(80).height(80).color(Color.White)
}
SmartDialog.showLoading()
// 支持入参,可以在特殊场景下灵活配置
SSmartDialog.showLoading({ builderArgs: 1 })
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" })
export function randomColor(): string {
const letters: string = '0123456789ABCDEF';

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())
}
