A well-tested, adaptable, lightweight <Popover> component for react-native. Great for use in Tablets; you can put entire views that you would normally show in a modal (on a smaller device) into a popover, optionally give it an anchor point, and have it float on top of all of the other views.

It is written entirely in JavaScript, but uses React Native's native driver for responsive animations, even when the JS thread is busy.

The <Popover> is able to handle dynamic content and adapt to screen size changes while showing, and will move out of the way for on-screen keyboards automatically.

Table of Contents
  • Moves to avoid keyboard
  • Ability to show from a view, from a rect, or float in center of screen
  • Adapts to changing content size
  • Automatically detects best placement on screen
  • Moves to stay visible on orientation change or when entering split-screen mode
  • (Optional) Integration with React Navigation

You can play around with the various features using the Expo test app. Source Code: react-native-popover-view-test-app

This is a fork of react-native-popover, originally created by Jean Regisser but since abandoned.

I have rebuilt most of the library from the ground up for improved handling of changing screen sizes on tablets (split-screen mode), a redesigned automatic placement algorithm, and ES6 compatibility.

Similar forks exist on Github (such as react-native-modal-popover), but this is the first to be published on NPM as far as I know.

npm i react-native-popover-view

or

yarn add react-native-popover-view
import Popover from 'react-native-popover-view'

...
  render (
    <Popover
      isVisible={this.state.isVisible}>
      <CustomElement />
    </Popover>
  )
Prop Type Optional Default Description
isVisible bool No false Show/Hide the popover
fromView ref Yes null The ref of the view that should anchor the popover.
fromRect rect Yes null Alternative to fromView. Rectangle at which to anchor the popover.
displayArea rect Yes screen rect Area where the popover is allowed to be displayed
placement string Yes 'auto' How to position the popover - top | bottom | left | right | auto. When 'auto' is specified, it will determine the ideal placement so that the popover is fully visible within displayArea.
onClose function Yes Callback to be fired when the user taps outside the popover
doneClosingCallback function Yes Callback to be fired when the popover is finished closing (after animation)
showInModal bool Yes true Whether the popover should be encapsulated in the Modal view from RN, which allows it to show above all other content, or just be present in the view hierarchy like a normal view.
arrowStyle object Yes {} The style of the arrow that points to the rect. Supported options are width, height, and backgroundColor. You can use {backgroundColor: 'transparent'} to hid the arrow completely.
popoverStyle object Yes {} The style of the popover itself. You can override the borderRadius, backgroundColor, or any other style prop for a View.
showBackground bool Yes true Whether the background behind the popover darkens when the popover is shown.
animationConfig object Yes An object containing any configuration options that can be passed to Animated.timing (e.g. { duration: 600, easing: Easing.inOut(Easing.quad) }). The configuration options you pass will override the defaults for all animations.
verticalOffset number Yes 0 The amount to vertically shift the popover on the screen. In certain Android configurations, you may need to apply a verticalOffset of -StatusBar.currentHeight for the popover to originate from the correct place.
debug bool Yes false Set this to true to turn on debug logging to the console. This is useful for figuring out why a Popover isn't showing.

If neither fromRect or fromView are provided, the popover will float in the center of the screen.

rect is an object with the following properties: {x: number, y: number, width: number, height: number}. You can create the object yourself, or import Popover, { Rect } from 'react-native-popover-view and create a rect by calling new Rect(x, y, width, height).

Likewise, size is an object with the following properties: {width: number, height: number}. You can create the object yourself, or import Popover, { Size } from 'react-native-popover-view and create a rect by calling new Size(width, height).

import React, { Component } from 'react';
import Popover from 'react-native-popover-view';
import {
  AppRegistry,
  StyleSheet,
  Text,
  TouchableHighlight,
  View,
} from 'react-native';

class PopoverExample extends Component {
  state = {
    isVisible: false
  }

  showPopover() {
    this.setState({isVisible: true});
  }

  closePopover() {
    this.setState({isVisible: false});
  }

  render() {
    return (
      <View style={styles.container}>
        <TouchableHighlight ref={ref => this.touchable = ref} style={styles.button} onPress={() => this.showPopover()}>
          <Text>Press me</Text>
        </TouchableHighlight>

        <Popover
          isVisible={this.state.isVisible}
          fromView={this.touchable}
          onClose={() => this.closePopover()}>
          <Text>I'm the content of this popover!</Text>
        </Popover>
      </View>
    );
  }
});

var styles = StyleSheet.create({
  container: {
    flex: 1,
    alignItems: 'center',
    justifyContent: 'center',
    backgroundColor: 'rgb(43, 186, 180)',
  },
  button: {
    borderRadius: 4,
    padding: 10,
    marginLeft: 10,
    marginRight: 10,
    backgroundColor: '#ccc',
    borderColor: '#333',
    borderWidth: 1,
  }
});

AppRegistry.registerComponent('PopoverExample', () => PopoverExample);

To use this library with React Navigation for deep integration, see react-navigation-popover.

In all cases, start by passing the debug={true} prop to the Popover, to see if the debug output can help you figure out the issue.

Show fromView not working

First, make sure that the ref is defined prior to showing the Popover. If you set the Popover's isVisible prop to true while the variable passed into fromView is undefined, the Popover will show centered on the screen.

If you pass in a fromView prop, but the Popover still shows centered on the screen on an Android device, try adding these props to the component whose ref you passed in to fromView:

  • renderToHardwareTextureAndroid={true}
  • collapsable={false}

See facebook/react-native#3282 and SteffeyDev#28 for more info.

1.0 to 1.1

This version moved the react-navigation portion of this project to it's own repository: react-navigation-popover. To use with react-navigation, install that npm package change import { createPopoverStackNavigator } from 'react-native-popover-view' to import createPopoverStackNavigator from 'react-navigation-popover'.

0.7 to 1.0

The only breaking change in version 1.0 was renaming PopoverStackNavigator to createPopoverStackNavigator, to match the react-navigation other navigation functions.

0.5 to 0.6

Version 0.6 brought some large changes, increasing efficiency, stability, and flexibility. For React Navigation users, there is a new prop, showInPopover, that you might want to pass to createPopoverStackNavigator if you want to customize when to show stack views in a Popover. This replaces PopoverNavigation.shouldShowInPopover. See the new setup instructions below for details.

Pull requests are welcome; if you find that you are having to bend over backwards to make this work for you, feel free to open an issue or PR! Of course, try to keep the same coding style if possible and I'll try to get back to you as soon as I can.

Original codebase created by Jean Regisser jean.regisser@gmail.com (https://github.com/jeanregisser) as react-native-popover, which has been abandoned.
