javascript - react 导航选项卡导航器中的淡入淡出动画

Question

我正在使用 React Navigation 选项卡导航器和 React Native Material 底部导航，它目前在屏幕之间滑动。我如何让它像 Material Design Guidelines 所建议的那样从一个屏幕淡入淡出到另一个屏幕。

Router.js

import React from 'react';
import { TabNavigator, StackNavigator, NavigationActions } from 'react-navigation';
import { NavigationComponent } from 'react-native-material-bottom-navigation';
import Icon from 'react-native-vector-icons/MaterialIcons';
import { MAIN_COLOR, BOTTOM_BAR_COLOR, BOTTOM_BAR_ICON_COLOR } from '../config';
import { Classes, Settings, Search, SplashScreen } from '../components/screens';
import Login from '../components/screens/Login';
import Main from '../Main';

export const Tabs = TabNavigator({
  Classes: {
    screen: Classes,
    navigationOptions: {
      tabBarLabel: 'Classes',
      tabBarIcon: () => <Icon size={24} name="list" color={BOTTOM_BAR_ICON_COLOR} />,
    },
  },
  Search: {
    screen: Search,
    navigationOptions: {
      tabBarLabel: 'Search',
      tabBarIcon: () => <Icon size={24} name="search" color={BOTTOM_BAR_ICON_COLOR} />,
    },
  },
  Settings: {
    screen: Settings,
    navigationOptions: {
      tabBarLabel: 'Settings',
      tabBarIcon: () => <Icon size={24} name="settings" color={BOTTOM_BAR_ICON_COLOR} />,
    },
  },
}, {
  tabBarComponent: NavigationComponent,
  tabBarPosition: 'bottom',
  swipeEnabled: false,
  tabBarOptions: {
    bottomNavigationOptions: {
      labelColor: BOTTOM_BAR_ICON_COLOR,
      rippleColor: MAIN_COLOR,
      shifting: false,
      tabs: {
        Search: {
          barBackgroundColor: BOTTOM_BAR_COLOR,
          activeIcon: <Icon size={24} name="search" color={MAIN_COLOR} />,
          activeLabelColor: MAIN_COLOR,
        },
        Classes: {
          barBackgroundColor: BOTTOM_BAR_COLOR,
          activeIcon: <Icon size={24} name="list" color={MAIN_COLOR} />,
          activeLabelColor: MAIN_COLOR,
        },
        Settings: {
          barBackgroundColor: BOTTOM_BAR_COLOR,
          activeIcon: <Icon size={24} name="settings" color={MAIN_COLOR} />,
          activeLabelColor: MAIN_COLOR,
        },
      },
    },
  },
});

这就是我想要的效果

我最终通过在选项卡导航器中禁用动画来修复错误。
