react-native-popover-view

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.

Popover Features

• 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

Demo App

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

A Note on Origins

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.

Installation

npm i react-native-popover-view

or

yarn add react-native-popover-view

Standalone Usage

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

...
  render (
    <Popover
      isVisible={this.state.isVisible}>
      <CustomElement />
    </Popover>
  )

Props

Prop | Type | Optional | Default | Description ----------------- | -------- | -------- | ----------- | ----------- isVisible | bool | No | false | Show/Hide the popover mode | string | Yes | 'rn-modal' | One of: 'rn-modal', 'js-modal', 'tooltip'. See Mode section below for details. 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. fromDynamicRect | function | Yes | | Same as fromRect, but instead of passing a static rectangle, pass a function that takes the display area dimensions as parameters: (displayAreaWidth, displayAreaHeight) => new Rect(...) 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. 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. popoverStyle | object | Yes | {} | The style of the popover itself. You can override the borderRadius, backgroundColor, or any other style prop for a 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. backgroundStyle | object | Yes | {} | The style of the background that fades in. onOpenStart | function | Yes | | Callback to be fired when the open animation starts (before animation) onOpenComplete | function | Yes | | Callback to be fired when the open animation ends (after animation) onRequestClose | function | Yes | | Callback to be fired when the user taps outside the popover (on the background) or taps the "hardware" back button on Android onCloseStart | function | Yes | | Callback to be fired when the popover starts closing (before animation) onCloseComplete | function | Yes | | Callback to be fired when the popover is finished closing (after animation) 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).

Mode

The Popover can show in three modes:

• Popover.MODE.RN_MODAL ('rn-modal')
• Popover.MODE.JS_MODAL ('js-modal')
• Popover.MODE.TOOLTIP ('tooltip')

RN Modal (Default)

Shows the popover full screen in a React Native Modal Component. The upside is that it is guaranteed to show on top of all other views, regardless of where the Popover component is placed in the view hierarchy. The downside is that you can only have one Modal shown at any one time, so this won't work for nested popovers or if you use a Modal for other reasons. Taps to the area outside the popover will trigger the onRequestClose callback.

JS Modal

Shows the popover in the space provided, filling the Popover component's parent. This looks identical to rn-modal if the Popover component's parent is a top-level view, but may look weird if the Popover is nested inside a few views with their own padding and margins. With careful component hierarchy design, this can allow for nested popovers and popovers in other Modals. Taps to the area outside the popover will trigger the onRequestClose callback.

Tooltip

Shows the Popover without taking over the screen, no background is faded in and taps to the area around the popover fall through to those views (as expected). The onRequestClose callback will never be called, so the Popover will have to be dismissed some other way.

Full Example

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}
          onRequestClose={() => 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);

Usage with React Navigation

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

Troubleshooting

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 https://github.com/facebook/react-native/issues/3282 and https://github.com/SteffeyDev/react-native-popover-view/issues/28 for more info.

Upgrading

1.x to 2.0

• onClose has been renamed to onRequestClose (for clarity and consistency with normal RN Modals)
• New mode prop replaces showInModal. Replace showInModal={false} with mode={Popover.MODE.JS_MODAL}
• doneClosingCallback has been renamed onCloseComplete
• New backgroundStyle prop replaces showBackground. Replace showBackground={false} with backgroundStyle={{ backgroundColor: 'transparent' }}
• Fix in version 2.0 means that verticalOffset may no longer be needed, so if you are using it be sure to test

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.
