您需要使用ApplicationProvider并提供@eva-design/eva或@eva-design/material主题属性。

import React, {useState} from 'react';
import { ApplicationProvider, Layout, Text } from '@ui-kitten/components';
import * as eva from '@eva-design/eva';
import * as material from '@eva-design/material';

export default () => (
  const [theme, setTheme] = useState()
  <ApplicationProvider {...eva} theme={eva.light}>
    <Layout>
      <Button onPress={() => setTheme(material.light)}>
        Siwtch to material
      </Button>
    </Layout>
  </ApplicationProvider>
);
