Marker click event on react native maps not working in react ios

Question

I have tried by calling onPress method in MapView.Marker Tab, but its not working.

This method for tracking marker click:

markerClic         


        

Answer 1

onCalloutPress={this.markerClick()} worked for me. Hope this helps.

Answer 2

To add to Anil's answer, you can use the 'onCalloutPress' callback on Marker to handle the callout press event, so that you don't need a TouchableHighlight in the callout:

<MapView.Marker
   coordinate={marker.coordinate}
   title={marker.title}
   description={marker.description}
   onCalloutPress={this.markerClick}>
   <MapView.Callout tooltip style={styles.customView}>
       <View style={styles.calloutText}>
          <Text>{marker.title}{"\n"}{marker.description}</Text>
       </View>
   </MapView.Callout>
</MapView.Marker>

Answer 3

<MapView.Marker key={index} coordinate={marker.coordinate}
    title={marker.title}
    description={marker.description}
    onPress={e => this.onPressMarker(e,index)}

You just need to add <MapView.Callout> in <MapView.Marker> tag. Custom callout- you can customize marker info click window as your requirement.

I have used TouchableHighlight for marker info window click, so that you can able to redirect user to other screen on click of custom callout.

<View style={styles.mainContainer}>
                  <MapView style={styles.map}
                          initialRegion={{
                              latitude: 37.78825,
                              longitude: -122.4324,
                              latitudeDelta: 0.0,
                              longitudeDelta: 0.0,
                            }}>
                            {this.state.markers.map((marker) => (
                              <MapView.Marker
                                coordinate={marker.coordinate}
                                title={marker.title}
                                description={marker.description}>
                                  <MapView.Callout tooltip style={styles.customView}>
                                      <TouchableHighlight onPress= {()=>this.markerClick()} underlayColor='#ffffdffffd'>
                                          <View style={styles.calloutText}>
                                              <Text>{marker.title}{"\n"}{marker.description}</Text>
                                          </View>
                                      </TouchableHighlight>
                                    </MapView.Callout>
                                </MapView.Marker>
                            ))}
                     </MapView>
                  </View>

Answer 5

Try to add a "key" in your marker:

{this.state.markers.map((marker, i) => (
    <MapView.Marker
      key={i}
      coordinate={marker.coordinate}
      title={marker.title}
      description={marker.description}
      onPress={() => this.markerClick()}
    />
 ))}

Just use 'i' for testing, you should use an unique id
