React-native-router-flux: Custom TabBar Component in v4

[thngdude]

Hi, I'm trying to implement a custom tabbar. As a control, I tried the following, which did not work:

import { TabNavigator, TabBarBottom } from 'react-navigation';

<Scene
          key="tabbar"
          gestureEnabled={false}
          tabs
          hideNavBar
          activeBackgroundColor='#ddd'
          component={TabNavigator}>

I also tried substituting TabNavigator with TabBarBottom and it still didn't work.

Resulting errors:
1) with TabNavigator --> "Cannot read property 'screen' of undefined"
2) with TabBarBottom --> "Cannot read property 'map' of undefined"

You have to use 'navigator' param, 'component' is used only by children to display screens

Thanks, @aksonov. Is this currently documented somewhere? Perhaps there's a README I missed.

Btw, this library is really awesome. Thanks for your work.

Ok, I got it working. I would be willing to contribute to add a section about this to the documentation for v4. However, this would be a first for me (contributing documentation) and could use some guidance.

<Scene
          key="tabbar"
          gestureEnabled={false}
          activeBackgroundColor='#ddd'
          tabs
          tabBarComponent={CustomTabBarComponent}>
            <Scene key="tab1" component={TabOne} title="Tab1"/>
            <Scene key="tab2" component={TabTwo} title="Tab2"/>
          </Scene>

You must add the tabs and tabBarComponent props, where the CustomTabBarComponent may extend a component such as TabBarBottom from the React Navigation library.

Great! Could you submit PR for docs?

Hi! Was this issue resolved? How did you finally made the custom slidable tabbar components?

[cicer1]

@kunaldodiya can you please share your CustomTabBarComponent?

[krunaldodiya]

I was able to make a custom tab bar following the method @thngdude described.

I'll prepare an example and submit a PR to add it to the docs. Meanwhile here's some code that should give some idea on how to implement the custom tab bar:

import { MaterialTopTabBar } from 'react-navigation-tabs';

class testbar extends MaterialTopTabBar {
    static propTypes = {

    }

    render() {
      return (
          <View>
            {
                this.props.navigationState.routes.map((element) => {
                  return (
                      <TouchableOpacity key={element.key} onPress={() => console.log(element.key)}>
                            <Text>{element.key}</Text>
                      </TouchableOpacity>
                  );
                })
            }
        </View>
      );
    }
}

export default testbar;

How to navigate to other tab in custom tabbar?

[micahkatz]

@ajaykumar97 you can use Actions['yourtabroute'](); to switch between tabs
For example, if you have Tab1 and Tab2, and you are currently in Tab1, you can call Actions['Tab2'](); to switch to Tab2

Thanks for your reply @micahkatz
