Question

我想在React Native中设置MapView上的标记，但我无法通过MapView的官方文档找到任何信息。
如果不允许这样做，我怎样才能在React Native中使用现有的反应模块，例如react-googlemaps？

Answer 1

谢谢@naoufal。最后，我能够在地图上显示标记以反应原生IOS。

<View style={styles.container}>
        <MapView style={styles.map}
          initialRegion={{
              latitude: 37.78825,
              longitude: -122.4324,
              latitudeDelta: 0.0,
              longitudeDelta: 0.0,
          }}
        >
        <MapView.Marker
            coordinate={{latitude: 37.78825,
            longitude: -122.4324}}
            title={"title"}
            description={"description"}
         />
      </MapView>
 </View>

对于地图和容器样式，我使用了以下样式：

 var styles = StyleSheet.create({

  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#F5FCFF',
  },
    map: {
      position: 'absolute',
      top: 0,
      left: 0,
      right: 0,
      bottom: 0,
    }
});

我参考了以下链接： React native IOS- Display Markers on map

Answer 2

您可以使用annotations prop.

设置标记

例如：

var markers = [
  {
    latitude: 45.65,
    longitude: -78.90,
    title: 'Foo Place',
    subtitle: '1234 Foo Drive'
  }
];

<MapView
  region={...}
  annotations={markers}
/>

Answer 3

import MapView, { Marker } from 'react-native-maps';

<View>
    <MapView
    style={styles.mapStyle}
    initialRegion={{
    latitude: 37.78825,
    longitude: -122.4324,
    latitudeDelta: 0.0922,
    longitudeDelta: 0.0421,
    }}
    >
        <Marker coordinate = {{latitude: 37.78825,longitude: -122.4324}}
         pinColor = {"purple"} // any color
         title={"title"}
         description={"description"}/>
    </MapView>
</View>

Answer 4

根据this issue，它还没有曝光。您无法使用Web-React软件包，React Native也不会像这样工作。

两个建议：

等待上述问题得到解决以获得正确的API
尝试使用WebView链接到带有注释的Google地图

我确实不确定＃2是否可行。

Answer 5

谢谢@zia_qureshi。最后，我能够在地图上显示标记以响应本机android。

import MapView, { Marker } from "react-native-maps";

const App = () => {
  const [region, setRegion] = useState({
    latitude: 51.5078788,
    longitude: -0.0877321,
    latitudeDelta: 0.009,
    longitudeDelta: 0.009
  });

  return (
    <MapView
      style={{ flex: 1 }}
      region={region}
      onRegionChangeComplete={region => setRegion(region)}
    >
      <Marker coordinate={{ latitude: 51.5078788, longitude: -0.0877321 }} />
    </MapView>
  );
};

export default App;

    </Marker>
</MapView>

对于那些寻找动态（例如，来自 API）而不是硬编码坐标的人；这是 Expo CLI 自动生成的屏幕之一的复制/粘贴片段，包括 React Hooks：

import axios from "axios";
import MapView from "react-native-maps";
import { Dimensions, StyleSheet } from "react-native";
import { Marker } from "react-native-maps";
import { Text, View } from "../components/Themed";

export default function TabTwoScreen() {
  const [markers, setMarkers] = useState(null);

  useEffect(() => {
    axios({
      method: "GET",
      url: "https://API_URL...",
      headers: {
        Authorization: `Bearer MY_TOKEN_ABC123...`,
        Accept: "application/json",
      },
    })
      .then((response) => {
        setMarkers(response.data.results);
      })
      .catch((error) => {
        console.log(error);
      });
  }, []); // "[]" makes sure the effect will run only once.

  return (
    <View style={styles.container}>
      <Text style={styles.title}>Tab Two</Text>
      <MapView style={styles.map}>
        {markers &&
          markers.map((marker: any, index: number) => (
            <Marker
              key={index}
              coordinate={{
                latitude: marker.location[1],
                longitude: marker.location[0],
              }}
              title={marker.title}
              description={marker.description}
            />
          ))}
      </MapView>
    </View>
  );
}

const styles = StyleSheet.create({
  // Add your styles here...
});

import MapView from 'react-native-maps';
<View style={StyleSheet.absoluteFillObject}>
        <MapView style={styles.map}
          showsUserLocation //to show user current location when given access
          loadingEnabled //to show loading while map loading
          style={styles.map}
          initialRegion={{
              latitude,
              longitude,
              latitudeDelta: 0.0922,
              longitudeDelta: 0.0421,
          }}
        >
        {

             locations && locations.map((location, index) => {
                   const {
                       coords: { latitude, longitude }
                          } = location;
                                return (
                                    <MapView.Marker
                                        key={index}
                                        coordinate={{ latitude, longitude }}
                                        title={"title"}
                                        description={"address"}
                                        // onPress={this.onMarkerPress(location)}
                                    />
                                )
                            })
                        }
      </MapView>
 </View>```

const styles = StyleSheet.create（{

map: {
  position: 'absolute',
  top: 0,
  left: 0,
  right: 0,
  bottom: 0,
}

}）;

“依赖项”：{ “ native-base”：“ ^ 2.13.8”， “ react”：“ 16.9.0”， “ react-native”：“ 0.61.2”， “ react-native-maps”：“ git + https://git@github.com/react-native-community/react-native-maps.git” }


Try using this. Hope it helps to mark for many locations. Happy Coding.

您可以尝试使用webview -

可以使用标记和其他选项。希望它会有所帮助！
