React Native react-navigation 导航使用详解(8)

(5)实现Android中界面跳转左右切换动画

react-navigation在Android中默认的界面切换动画是上下。如何实现左右切换呢?很简单的配置即可:

复制代码 代码如下:

import CardStackStyleInterpolator from 'react-navigation/src/views/CardStackStyleInterpolator'; 

然后在StackNavigator的配置下添加如下代码:

transitionConfig:()=>({ 
  screenInterpolator: CardStackStyleInterpolator.forHorizontal, 
}) 

(6)解决快速点击多次跳转

当我们快速点击跳转时,会开启多个重复的界面,如何解决呢。其实在官方git中也有提示,解决这个问题需要修改react-navigation源码:

找到scr文件夹中的addNavigationHelpers.js文件,替换为如下文本即可:

export default function<S: *>(navigation: NavigationProp<S, NavigationAction>) { 
 // 添加点击判断 
 let debounce = true; 
 return { 
   ...navigation, 
   goBack: (key?: ?string): boolean => 
     navigation.dispatch( 
       NavigationActions.back({ 
         key: key === undefined ? navigation.state.key : key, 
       }), 
     ), 
   navigate: (routeName: string, 
         params?: NavigationParams, 
         action?: NavigationAction,): boolean => { 
     if (debounce) { 
       debounce = false; 
       navigation.dispatch( 
         NavigationActions.navigate({ 
           routeName, 
           params, 
           action, 
         }), 
       ); 
       setTimeout( 
         () => { 
           debounce = true; 
         }, 
       500, 
       ); 
       return true; 
     } 
     return false; 
   }, 
  /** 
   * For updating current route params. For example the nav bar title and 
   * buttons are based on the route params. 
   * This means `setParams` can be used to update nav bar for example. 
   */ 
  setParams: (params: NavigationParams): boolean => 
   navigation.dispatch( 
    NavigationActions.setParams({ 
     params, 
     key: navigation.state.key, 
    }), 
   ), 
 }; 
}

以上就是我们实战中常用的属性和技巧。具体的操作还需要大家在实践过程中测试体会。希望对大家的学习有所帮助,也希望大家多多支持黑区网络。
