如何使用 createBottomTabNavigator 为 React Navigation 过渡设置动画？

Question

我花了最后一天试图找出如何使用 react-navigation 实现简单的淡入淡出屏幕转换，但我找不到一种方法让它与底部选项卡导航器一起使用。有人可以帮我吗？我已经广泛阅读了文档，但动画似乎只能通过堆栈导航器获得。

你能在这个小吃演示中进行过渡吗？

只需创建一个Animated.View 并将其附加到您的屏幕上。

const FadeHomeScreen = (props) => (
  <FadeInView>
    <HomeScreen {...props} />
  </FadeInView>
);

然后将其用于Tab.Screen

<Tab.Screen name="Home" component={FadeHomeScreen} />

只需在screenOptions 中添加unmountOnBlur: true

const screenOptions = {
    unmountOnBlur: true,
    headerShown: false,
};

<Tab.Navigator {...{ screenOptions }}>

您也可以使用react-native-reanimated 创建<FadeInView /> 组件
