  1. VideoDetail.js 视频详情组件
/**

 * @Description:
 */
import React, { Component } from "react";
import { StyleSheet, View, Text, Dimensions } from "react-native";
import VideoPlayer from "../components/VideoPlayer";

// Dimensions 用于获取设备宽、高、分辨率
const { width, height } = Dimensions.get("window");

type Props = {};
export default class VideoDetail extends Component<Props> {
  // 默认属性
  static defaultProps = {};

  // 属性类型
  static propTypes = {};

  // 构造
  constructor(props) {
    super(props);
    // 初始状态
    this.state = {
      options: {
        rate: 1.0, // 1.0表示默认速率
        volume: 3, // 声音大小
        paused: false, // 默认播放
        repeat: false, // 不重复播放
        muted: false, // 是否静音
        controls: true, // 显示控件
        resizeMode: "contain", // 等比缩放
        style: styles.backgroundVideo // 样式
      }
    };
  }

  // 渲染
  render() {
    const { params } = this.props.navigation.state;
    return (
      <View style={styles.container}>
        <VideoPlayer
          video={params.video}
          options={this.state.options}
          author={params.author}
        />
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    // justifyContent: "center",
    // alignItems: "center",
    backgroundColor: "#F5FCFF"
  },
  backgroundVideo: {
    width: width,
    height: (width * 9) / 16,
    // position: "absolute",
    // top: 0,
    // left: 0,
    // bottom: 0,
    // right: 0,
    backgroundColor: "#000"
  }
});

注:

  1. 如需全屏展示,使用 backgroundVideo 样式中的 绝对定位 样式。
  2. 如需置顶显示,使用 backgroundVideo 样式中的 宽、高等比缩放样式。
  3. 其他配置请参照官方文档:https://github.com/react-native-community/react-native-video
