react-native-google-places-autocomplete 给它一个值,而不仅仅是默认(初始)值

我有一个工作<TextInput>

<TextInput
      placeholder="Location"
      value={props.locationInput.toString()}
      onChangeText={location => props.updateLocationInput(location)}
    />

props.locationInput最初''但一旦应用程序启动时,一对夫妇异步功能火,并获得用户的当前位置,其填充props.locationInput(在终极版商店)。这意味着<TextInput>上面显示了用户到达时的当前位置。我想基本上完全按照上面的方式做,但是使用react-native-google-places-autocomplete

react-native-google-places-autocomplete做的initialise与props.locationInput值。它有一个getDefaultValue属性 eg getDefaultValue={() => props.locationInput.toString()},但是当 props.locationInput 改变时它不会改变,所以它永远不会显示用户当前的位置,因为它在初始化时没有设置。如何react-native-google-places-autocompleteprops.locationInput更改时更新

可能认为在用户当前位置进入之前我可能不需要渲染它,但这真的很混乱。

编辑:还考虑不使用插件,而是调用谷歌地点 API。

游戏晚了,但有一个名为setAddressText 的函数

例子:

setLocation(text) {
  this.placesRef && this.placesRef.setAddressText(text)
}
...
<GooglePlacesAutocomplete
ref={ref => {this.placesRef = ref}}
...
/>

在 GooglePlaceAutocomplete 组件上,您必须使用 onPress 事件来获取值。下面是一个例子:

<GooglePlacesAutocomplete
                placeholder='Event Location'
                minLength={2} // minimum length of text to search
                autoFocus={false}
                // Can be left out for default return key https://facebook.github.io/react-native/docs/textinput.html#returnkeytype
                listViewDisplayed='auto'    // true/false/undefined
                fetchDetails={true}
                renderDescription={row => row.description} // custom description render
                onPress={(data, details = null) => {
            // 'details' is provided when fetchDetails = true
            this.setState(
              {
                address: data.description, // selected address
                coordinates: `${details.geometry.location.lat},${details.geometry.location.lng}` // selected coordinates
              }
            );
          }}
                textInputProps={{
                  onChangeText: (text) => { console.warn(text) }
                }}
                getDefaultValue={() => ''}

                query={{
                  // available options: https://developers.google.com/places/web-service/autocomplete
                  key: 'XXXXXXXXXXXXXXZXZXXXXXXX',
                  language: 'en', // language of the results
                  types: 'geocode' // default: 'geocode'
                }}

                styles={{
                  textInputContainer: {
                    backgroundColor: 'rgba(0,0,0,0)',
                    borderTopWidth: 0,
                    borderBottomWidth:0,
                  },
                  description: {
                    fontWeight: 'bold',
                  },
                  textInput: {
                  marginLeft: 22,
                  marginRight: 0,
                  height: 38,
                  color: '#5d5d5d',
                  fontSize: 16,
                },
                  predefinedPlacesDescription: {
                    color: '#1faadb'
                  }
                }}
                value={props.location}
                onChangeText={props.onLocationChange}
                renderLeftButton={()  => <Text style={{ marginTop: 12, marginLeft:16, fontSize: 18 }}> Location </Text>}
                nearbyPlacesAPI='GooglePlacesSearch' // Which API to use: GoogleReverseGeocoding or GooglePlacesSearch
                GoogleReverseGeocodingQuery={{
                  // available options for GoogleReverseGeocoding API : https://developers.google.com/maps/documentation/geocoding/intro
                }}
                GooglePlacesSearchQuery={{
                  // available options for GooglePlacesSearch API : https://developers.google.com/places/web-service/search
                  rankby: 'distance',
                  types: 'food'
                }}

                filterReverseGeocodingByTypes={['locality', 'administrative_area_level_3']} // filter the reverse geocoding results by types - ['locality', 'administrative_area_level_3'] if you want to display only cities
                debounce={200} // debounce the requests in ms. Set to 0 to remove debounce. By default 0ms.

              />

使用react功能钩子

        <GooglePlacesAutocomplete
          ...
          ref={ref => {
            ref?.setAddressText('123 myDefault Street, mycity')
          }}
        />
