A reactive approach for the Google Maps Webservice API
- Places Autocomplete
- Reverse Geocoding from given
place_id
compile 'com.a99.rxplaces:library:0.1.0-alpha3'Add the following line to your proguard-rules.pro
-keep class com.a99.rxplaces.** { *; }
You should use the function create(GOOGLE_MAPS_API_AUTOCOMPLETE_KEY), where GOOGLE_MAPS_API_AUTOCOMPLETE_KEY is the generated key from the Google developer console:
val rxAutocomplete = RxAutocomplete.create(GOOGLE_MAPS_API_AUTOCOMPLETE_KEY)You can observe an EditText:
rxAutocomplete.observe(editText, options)You can also observe any String data source:
Observable<String> dataSource = Observable.just("place");
rxAutocomplete.observe(dataSource, options)You can customize any value provided from the Google Maps Place Autocomplete webservice:
val options = AutocompleteOptions.create {
offset { MIN_OFFSET }
location { latLng.latitude to latLng.longitude }
radius { RADIUS_IN_METERS }
language { locale.language }
types { AutocompleteType.CITIES } //Check the AutocompleteType class to get all the possible types
components { listOf(DEFAULT_COUNTRY) }
strictBounds { true }
}You can use the stateStream() to handle the provided events from the API:
rxAutocomplete.stateStream()
.observeOn(AndroidSchedulers.mainThread())
.subscribe {
when(it) {
AutocompleteState.QUERYING -> view.showProgress()
AutocompleteState.FAILURE -> view.showError()
AutocompleteState.SUCCESS -> view.hideProgress()
}
}- The default min key stroke is
3 - The default query interval is
2 seconds
To get the latitude and longitude from a given place, you can use the GeocodeRepository
You should use the function create(GOOGLE_MAPS_API_GEOCODE_KEY), where GOOGLE_MAPS_API_GEOCODE_KEY is the generated key from the Google developer console:
val geocodeRepository = GeocodeRepository.create(BuildConfig.GOOGLE_MAPS_API_GEOCODE_KEY)You can use the method reverseGeocode(placeId):
geocodeRepository.reverseGeocode(placeId)
.subscribeOn(Schedulers.io())
.take(1)
.observeOn(AndroidSchedulers.mainThread())
.subscribe(
{ view.dispatchGeocodeResult(it)},
{ view.showError() }
)You can easily get the result information through the API given functions, example:
private fun createResult(result: GeocodeResult) = Result(
latitude = result.geometry.location.lat,
longitude = result.geometry.location.lng,
formattedAddress = result.formattedAddress,
street = result.getStreetName(),
number = result.getStreetNumber(),
city = result.getCity(),
neighborhood = result.getNeighborhood(),
postalCode = result.getPostalCode(),
)Note: the API will return the long name attribute from the response.
