反应原生导航 v5 选项卡按不工作 [英] React native navigation v5 tab press not working

问题描述

如代码所示，tabPress 没有被调用，是我做错了还是我遗漏了什么，不幸的是我没有找到任何 React 导航版本 5 的代码示例.

As seen on the code, tabPress is not called, am i doing it wrong or am i missing something, unfortunately i have not found any code samples for react navigation version 5.

<Tab.Navigator labeled={false} barStyle={{backgroundColor: '#ffffff', height: 55}} options={{
        tabPress: ({navigation}) => {
            console.log('nav tab press triggered')
        }
    }}>
        <Tab.Screen name={`DeviceNavigatorTab`} component={DeviceNavigator} options={{
            tabBarIcon: ({tintColor}) => <Image source={require('../../images/feather_home-menu.png')}
                                                style={{width: 26, height: 26, tintColor}}/>,
            tabPress: ({navigation}) => {
                console.log('tab press triggered')
            }
        }} tabPress={() => { console.log('prop tab pressed') }}/>
        <Tab.Screen name={`AlarmNavigatorTab`} component={AlarmNavigator} options={{
            tabBarIcon: ({tintColor}) => <Image source={require('../../images/feather_alert-circle.png')}
                                                style={{width: 26, height: 26, tintColor}}/>,
        }}/>
        <Tab.Screen name={`ProfileNavigatorTab`} component={ProfileNavigator} options={{
            tabBarIcon: ({tintColor}) => <Image source={require('../../images/feather_user.png')}
                                                style={{width: 26, height: 26, tintColor}}/>,
        }} />
    </Tab.Navigator>

推荐答案

我在文档中发现了一些我以前从未见过的新东西，这是向屏幕添加侦听器的方法，每次用户单击选项卡时，它都会在此选项卡内的第一个堆栈屏幕

I found something new in documentation, that i have not seen before, this is the way to add listener to screen, every time user clicks on tab, it goes to first stack screen inside this tab

https://reactnavigation.org/docs/navigation-事件/#listeners-prop-on-screen

<Tab.Screen 
  name="DeviceNavigatorTab" 
  component={DeviceNavigator} 
  listeners={({ navigation, route }) => ({
    tabPress: e => {
      if (route.state && route.state.routeNames.length > 0) {
          navigation.navigate('Device')
      }
    },
  })}
/>
