react-native-scrollable-tabs

react-native-scrollable-tab-view

This is probably my favorite navigation pattern on Android, I wish it were more common on iOS! This is a very simple JavaScript-only implementation of it for React Native. For more information about how the animations behind this work, check out the Rebound section of the React Native Animation Guide

Tested with react-native 0.15

Add it to your project

1. Run npm install react-native-scrollable-tab-view --save
2. var ScrollableTabView = require('react-native-scrollable-tab-view');

Demo

Basic usage

var ScrollableTabView = require('react-native-scrollable-tab-view');
 
var App = React.createClass({
  render() {
    return (
      <ScrollableTabView>
        <ReactPage tabLabel="React" />
        <FlowPage tabLabel="Flow" />
        <JestPage tabLabel="Jest" />
      </ScrollableTabView>
    );
  }
});

Injecting a custom tab bar

Suppose we had a custom tab bar called CustomTabBar, we would inject it into our ScrollableTabView like this:

var ScrollableTabView = require('react-native-scrollable-tab-view');
var CustomTabBar = require('./CustomTabBar');
 
var App = React.createClass({
  render() {
    return (
      <ScrollableTabView renderTabBar={() => <CustomTabBar someProp={'here'} />}>
        <ReactPage tabLabel="React" />
        <FlowPage tabLabel="Flow" />
        <JestPage tabLabel="Jest" />
      </ScrollableTabView>
    );
  }
});

Example

See examples/FacebookTabsExample.

Props

• renderTabBar (Function:ReactComponent) - should return a component to use as the tab bar. The component has goToPage, tabs, activeTab and ref added to the props, and should implement setAnimationValue to be able to animate itself along with the tab content.
• tabBarPosition (String) - if "top", the tab bar will render above the tabs. If "bottom", the tab bar will render below the tabs. Defaults to "top".
• onChangeTab (Function) - function to call when tab changes, should accept 1 argument which is an Object containing two keys: i: the index of the tab that is selected, ref: the ref of the tab that is selected
• onScroll (Function) - function to call when the pages are sliding, should accept 1 argument which is an Float number representing the page position in the slide frame.
• locked (Bool) - disables horizontal dragging to scroll between tabs, default is false.
• initialPage (Integer) - the index of the initially selected tab, defaults to 0 === first tab.
• children (ReactComponents) - each top-level child component should have a tabLabel prop that can be used by the tab bar component to render out the labels. The default tab bar expects it to be a string, but you can use anything you want if you make a custom tab bar.
• tabBarUnderlineColor (String) - color of the default tab bar's underline, defaults to navy
• tabBarBackgroundColor (String) - color of the default tab bar's background, defaults to white
• tabBarActiveTextColor (String) - color of the default tab bar's text when active, defaults to navy
• tabBarInactiveTextColor (String) - color of the default tab bar's text when inactive, defaults to black
• style (View.propTypes.style)
