英文:
Getting name of hospital closest to user without needing to use the actual Google map just the places api
问题
我需要这个应用程序查找用户最近的医院名称并在TextView中显示出来，我所看到的关于此的示例都是使用实际的Google地图和Places API，但我需要只使用Places API来获取医院的名称并返回它。这是我目前的代码（在这里我尝试记录名称）：
private void findHospital() {
List<Place.Field> placeFields = Arrays.asList(Place.Field.NAME);
FetchPlaceRequest fetchPlaceRequest = FetchPlaceRequest.builder("Hospital", placeFields).build();
placesClient.fetchPlace(fetchPlaceRequest).addOnSuccessListener(new OnSuccessListener<FetchPlaceResponse>() {
@Override
public void onSuccess(FetchPlaceResponse fetchPlaceResponse) {
Place place = fetchPlaceResponse.getPlace();
Log.i("Hospital", "Place found" + place.getName());
}
});
}
然而，代码抛出错误，以下是日志输出：
2020-04-10 16:15:32.877 24773-24773/com.example.blooddonorsystem E/AndroidRuntime: FATAL EXCEPTION: main

...

修复了权限问题，现在在调试中得到以下输出：

英文:
I need the app find the name of the closest hospital the user and display it in a TextView, the only examples I've seen of this is using the actual Google maps with the places API however I need to work just using the Places api to get the name of the hospital and return it. This the code I have so far (here I have tried the log the name):
private void findHospital() {
List<Place.Field> placeFields = Arrays.asList(Place.Field.NAME);
FetchPlaceRequest fetchPlaceRequest = FetchPlaceRequest.builder("Hospital",placeFields).build();
placesClient.fetchPlace(fetchPlaceRequest).addOnSuccessListener(new OnSuccessListener<FetchPlaceResponse>() {
@Override
public void onSuccess(FetchPlaceResponse fetchPlaceResponse) {
Place place = fetchPlaceResponse.getPlace();
Log.i("Hospital","Place found" + place.getName());
}
});
}
However the code throws an error, here's the logcat:

你必须首先初始化谷歌地点 SDK。
if (!Places.isInitialized()) {
Places.initialize(getApplicationContext(), getString(R.string.api_key), Locale.US);
}
英文:
You have to first initialize google places sdk.
if (!Places.isInitialized()) {
Places.initialize(getApplicationContext(), getString(R.string.api_key), Locale.US);
}
