react-native-smartrefreshlayout

本项目基于 react-native-smartrefreshlayout 开发。

该第三方库的仓库已迁移至 Gitcode，且支持直接从 npm 下载，新的包名为：@react-native-ohos/react-native-smartrefreshlayout 版本所属关系如下：

简介

react-native-smartrefreshlayout 是一个基于 Android SmartRefreshLayout 封装的下拉刷新组件库，提供 SmartRefreshControl、AnyHeader、DefaultHeader、ClassicsHeader、StoreHouseHeader 等多种刷新头组件，支持下拉刷新、自动刷新、越界拖动等丰富的刷新特性与回调事件。

下载安装

进入到工程目录并输入以下命令：

npm

npm install @react-native-ohos/react-native-smartrefreshlayout

yarn

yarn add @react-native-ohos/react-native-smartrefreshlayout

Link

使用AutoLink的工程需要根据该文档配置，Autolink框架指导文档：https://gitcode.com/CPF-RN/ohos_react_native/blob/master/docs/zh-cn/Autolinking.md

如您使用的版本支持 Autolink，并且工程已接入 Autolink，可跳过ManualLink配置。

使用示例

下面的代码展示了这个库的基本使用场景：

import React, { useState } from "react";
import {
  View,
  Text,
  FlatList,
  StyleSheet,
  TouchableOpacity,
} from "react-native";
import {
  SmartRefreshControl,
  AnyHeader,
} from "react-native-smartrefreshlayout";

const App = () => {
  const [text, setText] = useState("状态");
  const [text1, setText1] = useState("刷新时间");

  const [headerHeight, setHeaderHeight] = useState(66);
  const [color, setColor] = useState("#fff000");

  const [data, setData] = useState([
    { id: 1, text: "Item 1" },
    { id: 2, text: "Item 2" },
    { id: 3, text: "Item 3" },
    { id: 4, text: "Item 4" },
    { id: 5, text: "Item 5" },
    { id: 6, text: "Item 6" },
    { id: 7, text: "Item 7" },
    { id: 8, text: "Item 8" },
    { id: 9, text: "Item 9" },
    { id: 10, text: "Item 10" },
    { id: 11, text: "Item 11" },

    // ... more data ...
  ]);

  const renderItem = ({ item }) => (
    <View style={styles.item}>
      <Text style={styles.item}>{item.text}</Text>
    </View>
  );
  let smartRefreshControlRef: React.RefObject<SmartRefreshControl>;
  return (
    <View>
      <TouchableOpacity
        onPress={() => {
          smartRefreshControlRef.finishRefresh({ delayed: -1, success: true });
        }}
      >
        <Text style={{ height: 40, width: "100%", backgroundColor: "red" }}>
          finish
        </Text>
      </TouchableOpacity>

      <TouchableOpacity
        onPress={() => {
          setHeaderHeight(headerHeight == 66 ? 132 : 66);
        }}
      >
        <Text style={{ height: 40, width: "100%", backgroundColor: "pink" }}>
          切换高度 66/132
        </Text>
      </TouchableOpacity>

      <TouchableOpacity
        onPress={() => {
          setColor(color === "#fff000" ? "red" : "#fff000");
        }}
      >
        <Text style={{ height: 40, width: "100%", backgroundColor: "green" }}>
          切换颜色（正在刷新中不支持切换背景色）
        </Text>
      </TouchableOpacity>

      <Text style={{ height: 40, width: "100%", backgroundColor: "" }}>
        {text}
      </Text>
      <Text style={{ height: 40, width: "100%", backgroundColor: "" }}>
        {text1}
      </Text>
      <SmartRefreshControl
        ref={(ref) => (smartRefreshControlRef = ref)}
        primaryColor={color}
        headerHeight={headerHeight}
        style={{ height: 500, width: "100%", backgroundColor: "#ffcc00" }}
        onHeaderMoving={(e) => {
          setText("onHeaderMoving" + JSON.stringify(e.nativeEvent));
        }}
        onRefresh={() => {
          setText1("时间：" + new Date().getTime() + "onRefresh触发刷新");
        }}
        HeaderComponent={
          <AnyHeader style = {{ height: 0 }}>
            <Text style={{ height: 66, width: "100%" }}>{text}</Text>
          </AnyHeader>
        }
      >
        <FlatList
          style={{ flex: 1, height: "100%", width: "100%" }}
          bounces={false}
          data={data}
          renderItem={renderItem}
          keyExtractor={(item) => item.id.toString()}
        />
      </SmartRefreshControl>
    </View>
  );
};

const styles = StyleSheet.create({
  item: {
    padding: 16,
    borderBottomWidth: 1,
    borderBottomColor: "#ccc",
    width: 100,
    height: 100,

SmartRefreshControl

组件 AnyHeader

当前组件支持

组件 DefaultHeader/ClassicsHeader

组件 StoreHouseHeader

当前组件支持

组件 MeaterialHeader

当前组件支持

无自有属性（仅继承 ViewProps）。该组件为鸿蒙侧额外导出，上游 index.js 未导出 MaterialHeader。

API

遗留问题

• SmartRefreshLayout 包裹 FlatList 组件，多次下拉刷新，item 会回弹：Issue #11
• SmartRefreshLayout 的StoreHouseHeader刷新头，暂不支持透明度的变化：Issue #45
