HarmonyOS 鸿蒙Next 自定义弹窗选择

您好，自定义全局的dialog演进是以UIcontext里的openCuctomDialog为准，可以不绑定组件，直接使用；

但是UIContext里支持的自定义功能并不多， 比如弹框背景圆角、宽高、边框等设置。可以自定义一个Builder，在里面做弹框背景圆角、宽高、边框等设置，参考示例如下：

import { BusinessError } from '@ohos.base';

import { ComponentContent } from "@ohos.arkui.node";

class Params {

text: string = "";

constructor(text: string) {
  this.text = text;
}
}

@Builder
function buildText(params: Params) {

Column() {

Text(params.text)
.fontSize(50)
.fontWeight(FontWeight.Bold)
.margin({bottom: 36})
}.backgroundColor('#FFF0F0F0')

}

@Entry
@Component
struct Index {

@State message: string = "hello"

build() {

Row() {

Column() {

Button("click me")
.onClick(() => {

let uiContext = this.getUIContext();

let promptAction = uiContext.getPromptAction();

let contentNode = new ComponentContent(uiContext, wrapBuilder(buildText), new Params(this.message));

try {

promptAction.openCustomDialog(contentNode);

} catch (error) {

let message = (error as BusinessError).message;
let code = (error as BusinessError).code;

console.error(`OpenCustomDialog args error code is ${code}, message is ${message}`);

};
})
