将ThemeProvider包装为wix react-native-navigation V2

Question

我试图用react-native-elements ThemeProvider包装我的基于RNN v2的应用程序。如果包裹在单个组件中，ThemeProvider可以很好地使用相同的主题，但是如果使用Navigation注册则不能，我做错了什么？

    const theme = {
  colors: {
    primary: 'pink'
  }
};
// Register screens
Screens.forEach((ScreenComponent, key) =>
  // Navigation.registerComponent(key, () => ScreenComponent, Provider)
  Navigation.registerComponent(
    key,
    () => ScreenComponent,
    () => <ThemeProvider theme={theme}>{ScreenComponent}</ThemeProvider>
  )
);

我也试过这种方式..

import { Platform } from 'react-native';
import { colors, ThemeProvider } from 'react-native-elements';
import React from 'react';

const theme = {
  colors: {
    primary: 'pink'
  }
};

const Provider = ({ children }) => <ThemeProvider theme={theme}>{children}</ThemeProvider>;

export default Provider;

App.js
Screens.forEach((ScreenComponent, key) =>
  Navigation.registerComponent(key, () => ScreenComponent, Provider)

Answer 1

您可以使用提供程序包装组件，如下所示

Navigation.registerComponent(key, () => (props) =>
    <Provider>
      <ScreenComponent {...props} />
    </Provider>,
    () => ScreenComponent);

• 第一个参数：注册名称
• 第二个参数：generator函数，它返回包含Provider的组件
• 第三个参数：返回实际组件的生成器函数。这是必要的，因为RNN需要提升非反应静力学
