react-native構建基本頁面4---渲染電影串列-有解無憂

電影串列

import React, { Component } from 'react'
import { View, Image, Text, ActivityIndicator, FlatList, StyleSheet, TouchableHighlight } from 'react-native'

const styles = StyleSheet.create({
  movieTitle: {
    fontWeight: 'bold'
  }
})

// 匯入路由的組件
import { Actions } from 'react-native-router-flux'

export default class MovieList extends Component {
  constructor(props) {
    super(props)
    this.state = {
      movies: [], // 電影串列
      nowPage: 1, // 當前的頁碼
      totalPage: 0, // 總頁數
      pageSize: 15, // 每頁顯示的記錄條數
      isloading: true // 是否正在加載資料
    }
  }

  componentWillMount() {
    this.getMoviesByPage()
  }

  render() {
    return <View>
      {this.renderList()}
    </View>
  }

  // 根據頁碼獲取電影串列
  getMoviesByPage = () => {
    const start = (this.state.nowPage - 1) * this.state.pageSize
    const url = `https://api.douban.com/v2/movie/in_theaters?start=${start}&count=${this.state.pageSize}`

    fetch(url)
      .then(res => res.json())
      .then(data =https://www.cnblogs.com/ygjzs/p/> {
        this.setState({
          isloading: false,
          movies: this.state.movies.concat(data.subjects),
          totalPage: Math.ceil(data.total / this.state.pageSize)
        })
      })

    /* setTimeout(() => {
      this.setState({
        isloading: false,
        movies: require('./test_list.json').subjects,
        totalPage: 1
      })
    }, 1000) */
  }

  // 渲染電影串列的方法
  renderList = () => {
    if (this.state.isloading) {
      return <ActivityIndicator size="large"></ActivityIndicator>
    }
    return <FlatList
      data=https://www.cnblogs.com/ygjzs/p/{this.state.movies}
      keyExtractor={(item, i) => i} // 解決 key 問題
      renderItem={({ item }) => this.renderItem(item)} // 呼叫方法，去渲染每一項
      ItemSeparatorComponent={this.renderSeparator} //渲染分割線的屬性方法
      onEndReachedThreshold={0.5} // 距離底部還有多遠的時候，觸發加載更多的事件
      onEndReached={this.loadNextPage} // 當距離不足 0.5 的時候，觸發這個方法，加載下一頁資料
    />
  }

  // 渲染每項電影
  renderItem = (item) => {
    return
