Question

我正在制作一个React Native应用程序，该应用程序需要使用Google PlacesSuggestion作为react native。所以我用了一个包装：

react-native-google-places-autocomplete 这是代码：

<View style = {{margin:10,padding:20,flex:1}}>
            <GooglePlacesAutocomplete
            placeholder='Search'
            minLength={2} // minimum length of text to search
            autoFocus={false}
            returnKeyType={'search'} // 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
         //  ToastAndroid.show(JSON.stringify(data),ToastAndroid.LONG)

                let city = details.address_components[0].long_name
                let lat = details.geometry.location.lat
                let lng = details.geometry.location.lng
                let full_addr= details.formatted_address

            }}

            getDefaultValue={() => ''}

            query={{

                key: 'AIzaSyB-q60XaNf5nsz5678e1jaRg0KTs5Q1nPi2Zk',
                language: 'en', // language of the results
                types: 'geocode' // default: 'geocode'
            }}

            styles={{
                textInputContainer: {
                    width: '100%'
                },
                description: {
                    fontWeight: 'bold'
                }
            }}


            nearbyPlacesAPI='GooglePlacesSearch' // Which API to use: GoogleReverseGeocoding or GooglePlacesSearch

            GoogleReverseGeocodingQuery={{
                }}
            GooglePlacesSearchQuery={{

                rankby: 'distance',
                types: 'food'
            }}

            filterReverseGeocodingByTypes={[ 'political','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.

        />
            </View>

但是上面的代码出现了两个问题。输入任何位置时，我的响应都非常缓慢，我的意思是，输入位置的字符或单词后，需要2-3秒才能显示结果，有时却不显示任何结果，为什么？另外，如果我想根据道路名称和区域名称搜索地址，那么它也不会给我任何建议。为什么？我被这两个问题困扰，请在这两个问题上帮助我。预先感谢

Google Auto Places提供地点建议非常慢
