我有一个特定的地方有奇怪的问题。有什么想法吗？
这段代码运行正常，但是对于一个地方（由于aaa启动而意外选择 - 仅用于测试），它无法从缓冲区获取Place对象。甚至查询都是成功的（日志：PlaceAutocompleteAdapt：查询已完成。收到5个预测。） 不幸的是，它崩溃了应用程序。它使这个API非常危险，还有什么应该在try catch块中处理？
addressAutocompleteText.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
/*
Retrieve the place ID of the selected item from the Adapter.
The adapter stores each Place suggestion in a PlaceAutocomplete object from which we
read the place ID.
*/
final PlaceAutocompleteAdapter.PlaceAutocomplete item = ((MainActivity) getActivity()).mAdapter.getItem(position);
final String placeId = String.valueOf(item.placeId);
Log.i(TAG, "Autocomplete item selected: " + item.description);
/* Issue a request to the Places Geo Data API to retrieve a Place object with additional details about the place. */
PendingResult<PlaceBuffer> placeResult = Places.GeoDataApi.getPlaceById(((MainActivity) getActivity()).mGoogleApiClient, placeId);
placeResult.setResultCallback(new ResultCallback<PlaceBuffer>() {
@Override
public void onResult(PlaceBuffer places) {
if (!places.getStatus().isSuccess()) {
// Request did not complete successfully
Log.e(TAG, "Place query did not complete. Error: " + places.getStatus().toString());
places.release();
return;
}
try {
// Get the Place object from the buffer.
final Place place = places.get(0); // Throws IllegalStateException
if (null != place) {
coordinate = new Coordinate(place.getLatLng().latitude, place.getLatLng().longitude);
}
} catch (IllegalStateException e) {
Log.w(TAG, "Fail to get place or its coordinates");
}
places.release();
}
});
// hideKeyboard(addressAutocompleteText);
Log.i(TAG, "Called getPlaceById to get Place details for " + item.placeId);
}
});

添加条件&& places.getCount() > 0
文档示例：
Places.GeoDataApi.getPlaceById(mGoogleApiClient, placeId)
.setResultCallback(new ResultCallback<PlaceBuffer>() {
@Override
public void onResult(PlaceBuffer places) {
if (places.getStatus().isSuccess() && places.getCount() > 0) {
final Place myPlace = places.get(0);
Log.i(TAG, "Place found: " + myPlace.getName());
} else {
Log.e(TAG, "Place not found");
}
places.release();
}
});

还需要places.getCount（）检查。请参阅此处https://developers.google.com/places/android-api/place-details
答案 2 :(得分：1)
我也有同样的问题。
我从Place ID: ChIJD1eejrW35zsRDFfkT-PSbm4方法获得item.getPlaceId()，但当我Reverse Geocoding by Place ID时，我没有得到任何结果。
可能会有很多地方返回与此相同的结果，所以我希望Google能够识别出这个问题。
但是现在我已经这样做了：
/**
* Callback for results from a Places Geo Data API query that shows the first place result in
* the details view on screen.
*/
private ResultCallback<PlaceBuffer> fromPlaceResultCallback = new ResultCallback<PlaceBuffer>() {
@Override
public void onResult(@NonNull PlaceBuffer places) {
if (!places.getStatus().isSuccess()) {
places.release();
return;
}
// Get the Place object from the buffer.
if(places.getCount() > 0) {
// Got place details
Place place = places.get(0);
// Do your stuff
} else {
// No place details
Toast.makeText(SelectLocation.this, "Place details not found.", Toast.LENGTH_LONG).show();
}
places.release();
}
};

如果 placeId 在通话
中错误/无效，就会发生这种情况Places.GeoDataApi.getPlaceById(((MainActivity) getActivity()).mGoogleApiClient, placeId);
