簡單的切換頁面(相似於微信)


//在App.js中實現
import React from 'react'; import { StyleSheet, Text, View } from 'react-native'; import { StackNavigator, TabNavigator, TabBarBottom, } from 'react-navigation'; const MainView = TabNavigator({ MessageView:{screen:MessageView}, FriendView:{screen: FriendView}, MyView:{screen:MyView}, SetView:{screen:SetView}, },{ tabBarComponent:TabBarBottom, tabBarPosition:'bottom', swipeEnabled:false, tabBarOptions:{ // showLabel:false, style:{ height:70, } } });


//在你須要切換的頁面實現
import React, { Component } from 'react';
import {
  View,
  Text,
  StyleSheet,
  Button,
  Image,
  Dimensions,
  FlatList,
} from 'react-native';

export default class FriendView extends Component {
  static navigationOptions={
    title:'朋友',
    headerLeft:null,
    headerTitleStyle:{
        alignSelf:'center',
    },
    tabBarIcon:({ focused, tintColor})=>{
      if(focused==true){
        return(
          <Image
            style={{width:40,height:40}}
            source={require('../assets/images/icon2.png')}
          />
        )
      }else {
        return(
          <Image
            style={{width:35,height:35}}
            source={require('../assets/images/icon3.png')}
          />
        )
      }
    }
  }
