复现仓库

git@github.com:shixiaohu2206/taro-test.git 小程序基础库: 支付宝小程序基础库2.0 使用框架: React

复现步骤

1. yarn build:alipay 打包支付宝小程序
2. HUAWEI MateX2 折叠屏机型，进行真机测试
3. 开合折叠屏，观察页面是否有onResize相关的toast

期望结果

在开合折叠屏时，触发onResize事件

实际结果

在开合折叠屏时，没有触发onResize事件

补充信息

支付宝小程序中，在开合折叠屏时，未触发onResize事件

机型：HUAWEI MateX2 折叠屏，型号代码TET-AN000，HarmonyOS 4.0.0

使用了3种方式

1. Class Component，使用onResize
2. Functional Component，使用useResize
3. 使用 Taro.Current.page.onResize

以上都不触发

伪代码

import { View } from "@tarojs/components";
import Taro, { useLoad, useResize, showToast } from "@tarojs/taro";

import "./index.scss";

export default function Index() {
  useResize(() => {
    showToast({ title: "useResize" });
  });

  useLoad(() => {
    showToast({ title: "useLoad" });

    if (Taro.Current.page) {
      Taro.Current.page.onResize = () => {
        showToast({ title: "Taro.Current.page.onResize" });
      };
    }
  });

  return <View className="my">index</View>;
}

import React, { Component } from "react";
import { View } from "@tarojs/components";
import Taro, { useLoad, useResize, showToast } from "@tarojs/taro";

import "./index.scss";

class Index extends Component {
  onResize() {
    showToast({ title: "Component-onResize" });
  }

  render(): React.ReactNode {
    return <View>index2</View>;
  }
}

export default Index;

这里提供下曲线解法：

支付宝的原生组件提供onResize钩子： https://opendocs.alipay.com/mini/framework/page-detail?pathHash=15155d5c#events

在原生组件上绑定个onResize，再通过自定义事件通知到Taro组件内

/**
 * @see https://opendocs.alipay.com/mini/framework/page-detail?pathHash=15155d5c#events
 */
Component({
  rootEvents: {
    onResize: function (size) {
      Emitter.emit("ON_RESIZE_EVENT", size);
    }
  }
});

  // 监听onResize事件
  useEffect(() => {
   // do something
    const handleOnResize = () => {};

    Emitter.on("ON_RESIZE_EVENT", handleOnResize);
    return () => Emitter.off("ON_RESIZE_EVENT", handleOnResize);
  }, []);
