React Navigation 中的过渡背景颜色

React Navigation 是一个用于在 React Native 应用程序中实现导航功能的流行库。它提供了一种简单而强大的方式来管理应用程序中的屏幕和导航栈。在 React Navigation 中，我们可以通过自定义过渡来实现更丰富的用户界面体验。本文将介绍如何在 React Navigation 中实现过渡背景颜色，并提供相应的示例代码。

jsx
import { createStackNavigator } from '@react-navigation/stack';
import { TransitionSpecs } from '@react-navigation/stack';
const Stack = createStackNavigator();
const MyStack = () => {
  const transitionSpec = {
    open: TransitionSpecs.TransitionIOSSpec,
    close: TransitionSpecs.TransitionIOSSpec,
    cardStyleInterpolator: ({ current, next, index, layouts }) => {
      const backgroundColor = current.progress.interpolate({
        inputRange: [index - 1, index, index + 1],
        outputRange: ['#f0f0f0', '#ffffff', '#f0f0f0'],
      });
      return {
        cardStyle: {
          backgroundColor,
        },
      };
    },
  };
  return (
          screenOptions={{
        gestureEnabled: true,
        cardOverlayEnabled: true,
        ...transitionSpec,
      }}
    >
      {/* 屏幕配置 */}
    
  );
};
export default MyStack;

jsx
const MyStack = () => {
  // ...
  return (
          screenOptions={{
        gestureEnabled: true,
        cardOverlayEnabled: true,
        ...transitionSpec,
      }}
    >
              name="Home"
        component={HomeScreen}
      />
              name="Detail"
        component={DetailScreen}
      />
    
  );
};

jsx
import { useEffect } from 'react';
import { useNavigation } from '@react-navigation/native';
const DetailScreen = () => {
  const navigation = useNavigation();
  useEffect(() => {
    const unsubscribe = navigation.addListener('transitionStart', () => {
      navigation.setOptions({
        cardStyleInterpolator: ({ current, next, index, layouts }) => {
          const backgroundColor = current.progress.interpolate({
            inputRange: [index - 1, index, index + 1],
            outputRange: ['#f0f0f0', '#ffffff', '#f0f0f0'],
          });
          return {
            cardStyle: {
              backgroundColor,
            },
          };
        },
      });
    });
    return unsubscribe;
  }, [navigation]);
  // ...
  return (
    // ...
  );
};
