React Native Mapview component for iOS + Android
npm install react-native-maps-batteryReact Native Map components for iOS + Android
See Installation Instructions.
See Setup Instructions for the Included Example Project.
Due to the rapid changes being made in the React Native ecosystem, we are not officially going to
support this module on anything but the latest version of React Native. With that said, we will do
our best to stay compatible with older versions as much that is practical, and the peer dependency
of this requirement is set to "react-native": "*" explicitly for this reason. If you are using
an older version of React Native with this module though, some features may be buggy.
Since react-native 0.25.0, React should be required from node_modules.
React Native versions from 0.18 should be working out of the box, for lower
versions you should add react as a dependency in your package.json.
``js`
import MapView from 'react-native-maps';
or
`js`
var MapView = require('react-native-maps');
This MapView component is built so that features on the map (such as Markers, Polygons, etc.) are
specified as children of the MapView itself. This provides an intuitive and react-like API for
declaratively controlling features on the map.

#### Tile Overlay using tile server
jsx
import { UrlTile } from 'react-native-maps';
onRegionChange={this.onRegionChange}
>
* The url template of the tile server. The patterns {x} {y} {z} will be replaced at runtime
* For example, http://c.tile.openstreetmap.org/{z}/{x}/{y}.png
*/
urlTemplate={this.state.urlTemplate}
/**
* The maximum zoom level for this tile overlay. Corresponds to the maximumZ setting in
* MKTileOverlay. iOS only.
*/
maximumZ={19}
/>
`For Android: add the following line in your AndroidManifest.xml
xml
`
For IOS: configure App Transport Security in your app#### Tile Overlay using local tiles
Tiles can be stored locally within device using xyz tiling scheme and displayed as tile overlay as well. This is usefull especially for offline map usage when tiles are available for selected map region within device storage.
jsx
import { LocalTile } from 'react-native-maps';
onRegionChange={this.onRegionChange}
>
* The path template of the locally stored tiles. The patterns {x} {y} {z} will be replaced at runtime
* For example, /storage/emulated/0/mytiles/{z}/{x}/{y}.png
*/
pathTemplate={this.state.pathTemplate}
/**
* The size of provided local tiles (usually 256 or 512).
*/
tileSize={256}
/>
`For Android: LocalTile is still just overlay over original map tiles. It means that if device is online, underlying tiles will be still downloaded. If original tiles download/display is not desirable set mapType to 'none'. For example:
>
See OSM Wiki for how to download tiles for offline usage.
$3
Place components you that wish to overlay
underneath the MapView closing tag. Absolutely position these elements.`jsx
render() {
return (
/>
/>
);
}
`$3
Create the json object, or download a generated one from the google style generator.
jsx
// The generated json object
mapStyle = [ ... ]render() {
return (
onRegionChange={this.onRegionChange}
customMapStyle={mapStyle}
/>
);
}
`
For iOS, in addition to providing the you will need to do the following`jsx
import MapView, { PROVIDER_GOOGLE } from 'react-native-maps'// ...
customMapStyle={MapStyle}
>
`Then add the AirGoogleMaps directory:
https://github.com/airbnb/react-native-maps/blob/1e71a21f39e7b88554852951f773c731c94680c9/docs/installation.md#ios
An unofficial step-by-step guide is also available at https://gist.github.com/heron2014/e60fa003e9b117ce80d56bb1d5bfe9e0
Examples
To run examples:
bash
npm i
npm start#Android
npm run run:android
#iOS
npm run build:ios
npm run run:ios

The
component and its child components have several events that you can subscribe to.
This example displays some of them in a log as a demonstration. 
$3
 
$3
One can change the mapview's position using refs and component methods, or by passing in an updated
region prop. The component methods will allow one to animate to a given position like the native
API could. 
$3
$3
 
$3
The
component can be made to work with the Animated API, having the entire region prop
be declared as an animated value. This allows one to animate the zoom and position of the MapView along
with other gestures, giving a nice feel.Further, Marker views can use the animated API to enhance the effect.
 
Issue: Since android needs to render its marker views as a bitmap, the animations APIs may not be
compatible with the Marker views. Not sure if this can be worked around yet or not.
Markers' coordinates can also be animated, as shown in this example:
 
$3
 
$3
So far,
, , and are available to pass in as children to the
component. 
$3
Gradient polylines can be created using the
strokeColors prop of the component.
$3
Default markers will be rendered unless a custom marker is specified. One can optionally adjust the
color of the default marker by using the
pinColor prop. 
$3
Callouts to markers can be completely arbitrary react views, similar to markers. As a result, they
can be interacted with like any other view.
Additionally, you can fall back to the standard behavior of just having a title/description through
the
's title and description props.Custom callout views can be the entire tooltip bubble, or just the content inside of the system
default bubble.
 
$3
Markers can be customized by just using images, and specified using the
image prop.
$3
Markers are draggable, and emit continuous drag events to update other UI during drags.
 
$3
Enable lite mode on Android with
liteMode prop. Ideal when having multiple maps in a View or ScrollView.
$3
Poi are clickable, you can catch the event to get its information (usually to get the full detail from Google Place using the placeId).
$3
The MapView can accept an
AnimatedRegion value as its region prop. This allows you to utilize the Animated API to control the map's center and zoom.`jsx
import MapView, { AnimatedRegion, Animated } from 'react-native-maps';getInitialState() {
return {
region: new AnimatedRegion({
latitude: LATITUDE,
longitude: LONGITUDE,
latitudeDelta: LATITUDE_DELTA,
longitudeDelta: LONGITUDE_DELTA,
}),
};
}
onRegionChange(region) {
this.state.region.setValue(region);
}
render() {
return (
onRegionChange={this.onRegionChange}
/>
);
}
`$3
Markers can also accept an
value as a coordinate.`jsx
import Mapview, { AnimatedRegion, Marker } from 'react-native-maps';getInitialState() {
return {
coordinate: new AnimatedRegion({
latitude: LATITUDE,
longitude: LONGITUDE,
}),
};
}
componentWillReceiveProps(nextProps) {
const duration = 500
if (this.props.coordinate !== nextProps.coordinate) {
if (Platform.OS === 'android') {
if (this.marker) {
this.marker._component.animateMarkerToCoordinate(
nextProps.coordinate,
duration
);
}
} else {
this.state.coordinate.timing({
...nextProps.coordinate,
duration
}).start();
}
}
}
render() {
return (
coordinate={this.state.coordinate}
/>
);
}
`If you need a smoother animation to move the marker on Android, you can modify the previous example:
jsx
// ...componentWillReceiveProps(nextProps) {
const duration = 500
if (this.props.coordinate !== nextProps.coordinate) {
if (Platform.OS === 'android') {
if (this.marker) {
this.marker._component.animateMarkerToCoordinate(
nextProps.coordinate,
duration
);
}
} else {
this.state.coordinate.timing({
...nextProps.coordinate,
duration
}).start();
}
}
}
render() {
return (
coordinate={this.state.coordinate}
/>
);
}
`$3
jsx
import MapView, { Marker } from 'react-native-maps';getInitialState() {
return {
coordinate: {
latitude: LATITUDE,
longitude: LONGITUDE,
},
};
}
takeSnapshot () {
// 'takeSnapshot' takes a config object with the
// following options
const snapshot = this.map.takeSnapshot({
width: 300, // optional, when omitted the view-width is used
height: 300, // optional, when omitted the view-height is used
region: {..}, // iOS only, optional region to render
format: 'png', // image formats: 'png', 'jpg' (default: 'png')
quality: 0.8, // image quality: 0..1 (only relevant for jpg, default: 1)
result: 'file' // result types: 'file', 'base64' (default: 'file')
});
snapshot.then((uri) => {
this.setState({ mapSnapshot: uri });
});
}
render() {
return (
{ this.map = map }}>
Take Snapshot
);
}
`$3
Pass an array of marker identifiers to have the map re-focus.
 
$3
Pass an array of coordinates to focus a map region on said coordinates.

#### My map is blank
* Make sure that you have properly installed react-native-maps.
* Check in the logs if there is more informations about the issue.
* Try setting the style of the MapView to an absolute position with top, left, right and bottom values set.
* Make sure you have enabled Google Maps API in !Google developer console
javascript
const styles = StyleSheet.create({
map: {
...StyleSheet.absoluteFillObject,
},
});
`jsx
// other props
/>
`#### Inputs don't focus
* When inputs don't focus or elements don't respond to tap, look at the order of the view hierarchy, sometimes the issue could be due to ordering of rendered components, prefer putting MapView as the first component.
