Import

Demo

Basic usage

import React from "react";
import { ScrollableTabView } from "@ocean28799/react-native-scrollable-tabview";

export default function ScrollableTabview() {
  return (
    <ScrollableTabView>
      <Page1 tabLabel="Page 1" />
      <Page2 tabLabel="Page 2" />
      <Page3 tabLabel="Page 3" />
    </ScrollableTabView>
  );
}

Injecting a custom tab bar

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

import {ScrollableTabView} from '@ocean28799/react-native-scrollable-tabview'
import CustomTabBar from './CustomTabBar';

export default class App extends Component {
  render() {
    return (
      <ScrollableTabView renderTabBar={() => <CustomTabBar someProp={'here'} />}>
        <ReactPage tabLabel="React" />
        <FlowPage tabLabel="Flow" />
        <JestPage tabLabel="Jest" />
      </ScrollableTabView>
    );
  }
});``

To start you can just copy DefaultTabBar.

Changing between tabs

You can change tabs programmatically. Just use goToPage method.

import { ScrollableTabView } from "@ocean28799/react-native-scrollable-tabview";

export default class App extends Component {
  render() {
    return (
      <ScrollableTabView
        renderTabBar={() => <DefaultTabBar />}
        ref={(tabView) => {
          this.tabView = tabView;
        }}
      >
        <Text tabLabel="Tab #1">My</Text>
        <Text tabLabel="Tab #2">favorite</Text>
        <Text tabLabel="Tab #3">project</Text>
        <TouchableOpacity
          tabLabel="Back"
          onPress={() => this.tabView.goToPage(0)}
        >
          <Text>Lets go back!</Text>
        </TouchableOpacity>
      </ScrollableTabView>
    );
  }
}

Examples

Example APP.

Props

• renderTabBar (Function:ReactComponent) - accept 1 argument props and 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. You can manually pass the props to the TabBar component.
• tabBarPosition (String) Defaults to "top".
  • "bottom" to position the tab bar below content.
  • "overlayTop" or "overlayBottom" for a semitransparent tab bar that overlays content. Custom tab bars must consume a style prop on their outer element to support this feature: style={this.props.style}.
• 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.
• page (Integer) - set selected tab(can be buggy see #126
• 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.
• tabBarUnderlineStyle (View.propTypes.style) - style of the default tab bar's underline.
• 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
• textActiveStyle (Object) - Additional styles to the text when active
• textStyle (Object) - Additional styles to the default text
• inactiveTextColor (String) - color of the default text
• activeTextColor (String) - color of the text when active
• tabBarInactiveTextColor (String) - color of the default tab bar's text when inactive, defaults to black
• tabBarTextStyle (Object) - Additional styles to the tab bar's text. Example: {fontFamily: 'Roboto', fontSize: 15}
• style (View.propTypes.style) - Container style
• contentStyle (View.propTypes.style) - Content style
• contentProps (Object) - props that are applied to root ScrollView/ViewPagerAndroid. Note that overriding defaults set by the library may break functionality; see the source for details.
• scrollWithoutAnimation (Bool) - on tab press change tab without animation.
• prerenderingSiblingsNumber (Integer) - pre-render nearby # sibling, Infinity === render all the siblings, default to 0 === render current page.
• pullToRefresh (Function) - function to perform in case of a pull to refresh action. This function required a callback to stop the refresh animation. Follow the example bellow
• refreshControlStyle (React style Object) - Style object applied to the RefreshControl React Component.
• showsVerticalScrollIndicator (Bool) - Show scroll indicator

• showsHorizontalScrollIndicator (Bool) - Show scroll indicator

• disableTabBarOnLayout (Bool) - Used on ScrollableTabBar to disable auto Layout of tabs. Auto-Layout sometimes causes a flickering effect. To disable ==> <ScrollableTabBar disableTabBarOnLayout={true}/>

Pull to refresh example

import React, { Component } from "react";
import { ScrollableTabView } from "@ocean28799/react-native-scrollable-tabview";

export default class Test extends Component {
  //execute callback in order to stop the refresh animation.
  _onRefresh = (callback) => {
    networkRequest().then((response) => callback(response));
  };

  render() {
    return (
      <ScrollableTabView
        refreshControlStyle={{ backgroundColor: "red" }}
        pullToRefresh={this._onRefresh}
      >
        <ScrollView tabLabel="one">
          <View>
            <Text>One</Text>
          </View>
        </ScrollView>
        <ScrollView tabLabel="two">
          <View>
            <Text>Two</Text>
          </View>
        </ScrollView>
      </ScrollableTabView>
    );
  }
}
