NativeBase 的 "Icon and Expanded Icon Style" 未显示

NativeBase's "Icon and Expanded Icon Style" not showing

我是新手...我在安装时遗漏了一些东西

我的问题是为什么使用来自 nativebase.io 的简单代码复制和粘贴没有显示图标 所有功能的构建都是成功的,但只有东西是

1.左上 "icon with Header content st.." 文本未显示 2. 打开和关闭图标的右下角下拉菜单没有显示,看起来像是路径中缺少图像或图标

"dependencies": {
    "@react-native-community/masked-view": "^0.1.7",
    "@react-navigation/native": "^5.1.1",
    "@react-navigation/stack": "^5.2.3",
    "native-base": "^2.13.12",
    "react": "16.9.0",
    "react-native": "0.61.5",
    "react-native-gesture-handler": "^1.6.0",
    "react-native-reanimated": "^1.7.0",
    "react-native-safe-area-context": "^0.7.3",
    "react-native-screens": "^2.3.0",
    "react-navigation-stack": "^2.3.3"
  },

enter image description here

import React, { Component } from "react";
import { Container, Header, Content, Accordion } from "native-base";
const dataArray = [
  { title: "First Element", content: "Lorem ipsum dolor sit amet" },
  { title: "Second Element", content: "Lorem ipsum dolor sit amet" },
  { title: "Third Element", content: "Lorem ipsum dolor sit amet" }
];
export default class AccordionHeaderContentStyleExample extends Component {
  render() {
    return (
      <Container>
        <Header />
        <Content padder>
          <Accordion
            dataArray={dataArray}
            headerStyle={{ backgroundColor: "#b7daf8" }}
            contentStyle={{ backgroundColor: "#ddecf8" }}
          />
        </Content>
      </Container>
    );
  }
}
Can you try to add this code to `app/build.gradle` and uninstall the app from phone and reinstall again

    apply from: "../../node_modules/react-native-vector-icons/fonts.gradle"

谢谢,现在它可以工作了,但只有底部图标 + & -(顶部图标和文字没有)
