 render() {
    return (
      <View style={styles.container}>
        <FlatList
          data={this.props.data}
          renderItem={({ item }) => (
            <ListItem
              roundAvatar={true}
              avatar={{ uri: item.picture.thumbnail }}
              avatarStyle={styles.avatar}
              avatarContainerStyle={styles.avatarContainer}
              title={`${item.name.first} ${item.name.last}`}
              titleStyle={styles.title}
              rightTitle="20 Minutes Ago"
              rightTitleStyle={styles.rightTitle}
              rightTitleContainerStyle={styles.rightTitleContainer}
              subtitle="This was posted by the developer"
              subtitleStyle={styles.subtitle}
              subtitleContainerStyle={styles.subtitleContainer}
              subtitleNumberOfLines={5}
              hideChevron={true}
              containerStyle={styles.listItemContainer}
            />
          )}
        />
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1
  },
  listItemContainer: {
    flex: 1,
    borderBottomWidth: 0
  },
  seperator: {
    height: 1,
    width: "86%",
    backgroundColor: "#CED0CE",
    marginLeft: "12%"
  },
  avatar: {
    width: 50,
    height: 50
  },
  title: {
    marginLeft: 5,
    fontSize: 16,
    fontWeight: "600",
    color: "black"
  },
  subtitle: {
    marginLeft: 5,
    fontSize: 14,
    fontWeight: "normal"
  },
  subtitleContainer: {
    marginTop: 0
  }
});

推荐答案

根据最新稳定版文档 文档，道具 avatar 说它可以用作组件.

According to the latest stable version docs docs, the prop avatar says that it can be used as component.

如index.d.ts 文件

头像?:字符串 |ImageURISource |JSX.Element;

avatar?: string | ImageURISource | JSX.Element;

有很多方法可以解决这个问题，但最方便的方法是让所有元素响应式 使用头像组件 直接来自图书馆.

There are many ways to resolve this issue, but the convenient way, such that all the elements are responsive would be using Avatar component directly from the library.

 <ListItem
                    avatar={<Avatar rounded large source={{uri: 'Your URI'}} height={`YOUR_HEIGHT`} width={`YOUR_WIDTH`}/>}
                    title={`YOUR_TITLE`}
                    titleStyle={styles.title}
                    rightTitle="20 Minutes Ago"
                    rightTitleStyle={styles.rightTitle}
                    rightTitleContainerStyle={styles.rightTitleContainer}
                    subtitle="This was posted by the developer"
                    subtitleStyle={styles.subtitle}
                    subtitleContainerStyle={styles.subtitleContainer}
                    subtitleNumberOfLines={5}
                    hideChevron={true}
                    containerStyle={styles.listItemContainer} />

然后你可以自由地应用 Avatar 组件的 props 根据要求

Then you get the liberty to apply the Avatar component's props as per the requirement
