The approach I decided to use is the following:
Using WebView
from react-native.
Using openlayers.
Declare a variable in render method from your react-native class which contains the HTML code from a Map of openlayers:
render() {
var html = `
<!DOCTYPE html>
<html>
<head>
<title>Simple Map</title>
<link rel="stylesheet" href="https://openlayers.org/en/v3.20.0/css/ol.css" type="text/css">
<!-- The line below is only needed for old environments like Internet Explorer and Android 4.x -->
<script src="https://cdn.polyfill.io/v2/polyfill.min.js?features=requestAnimationFrame,Element.prototype.classList,URL"></script>
<script src="https://openlayers.org/en/v3.20.0/build/ol.js"></script>
</head>
<body>
<div id="map" class="map"></div>
<script>
var map = new ol.Map({
layers: [
new ol.layer.Tile({
source: new ol.source.OSM()
})
],
target: 'map',
view: new ol.View({
center: [0, 0],
zoom: 2
})
});
</script>
</body>
</html>
`
Then pass this variable to the WebView:
return (
<View style={styles.container}>
<WebView
ref={webview => { this.webview = webview; }}
source={{html}}
onMessage={this.onMessage}/>
</View>
);
}
}
If you want to communicate the react-native side with WebView side, take a look to the WebView example from react-native.
You can find more examples in the openlayers example page.
