【问题描述】：
我已实现 Places SDK 并使用 materialSearchBar 库以编程方式获取位置预测，如下面的代码所示。
Places.initialize(MapsActivity.this, getString(R.string.google_maps_api));
placesClient = Places.createClient(this);
final AutocompleteSessionToken token = AutocompleteSessionToken.newInstance();
materialSearchBar.setOnSearchActionListener(new MaterialSearchBar.OnSearchActionListener() {
@Override
public void onSearchStateChanged(boolean enabled) {
}
@Override
public void onSearchConfirmed(CharSequence text) {
startSearch(text.toString(), true, null, true);
}
@Override
public void onButtonClicked(int buttonCode) {
if (buttonCode == MaterialSearchBar.BUTTON_NAVIGATION) {
if(drawerLayout.isDrawerOpen(GravityCompat.START)){
}else{
drawerLayout.openDrawer(GravityCompat.START);
}
}else if (buttonCode == MaterialSearchBar.BUTTON_BACK) {
materialSearchBar.disableSearch();
}
}
});
materialSearchBar.addTextChangeListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
RectangularBounds bounds = RectangularBounds.newInstance(
new LatLng(24.856165, 66.669119),
new LatLng(25.125024, 67.899587));
FindAutocompletePredictionsRequest predictionsRequest = FindAutocompletePredictionsRequest.builder()
.setCountry("PK")
.setTypeFilter(TypeFilter.ADDRESS)
.setLocationBias(bounds)
.setSessionToken(token)
.setQuery(s.toString())
.build();
placesClient.findAutocompletePredictions(predictionsRequest).addOnCompleteListener(new OnCompleteListener<FindAutocompletePredictionsResponse>() {
@Override
public void onComplete(@NonNull Task<FindAutocompletePredictionsResponse> task) {
if (task.isSuccessful()) {
FindAutocompletePredictionsResponse predictionsResponse = task.getResult();
if (predictionsResponse != null) {
predictionList = predictionsResponse.getAutocompletePredictions();
List<String> suggestionsList = new ArrayList<>();
for (int i = 0; i < predictionList.size(); i++) {
AutocompletePrediction prediction = predictionList.get(i);
suggestionsList.add(prediction.getFullText(null).toString());
}
materialSearchBar.updateLastSuggestions(suggestionsList);
if (!materialSearchBar.isSuggestionsVisible()) {
materialSearchBar.showSuggestionsList();
}
}
} else {
Log.i("mytag", "prediction fetching task unsuccessful");
}
}
});
}
@Override
public void afterTextChanged(Editable s) {
}
});
materialSearchBar.setSuggestionsClickListener(new SuggestionsAdapter.OnItemViewClickListener() {
@Override
public void OnItemClickListener(int position, View v) {
if (position >= predictionList.size()) {
return;
}
AutocompletePrediction selectedPrediction = predictionList.get(position);
String suggestion = materialSearchBar.getLastSuggestions().get(position).toString();
materialSearchBar.setText(suggestion);
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
materialSearchBar.clearSuggestions();
}
}, 1000);
InputMethodManager imm = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);
if (imm != null)
imm.hideSoftInputFromWindow(materialSearchBar.getWindowToken(), InputMethodManager.HIDE_IMPLICIT_ONLY);
final String placeId = selectedPrediction.getPlaceId();
List<Place.Field> placeFields = Arrays.asList(Place.Field.LAT_LNG, Place.Field.NAME, Place.Field.ADDRESS,Place.Field.ADDRESS_COMPONENTS);
FetchPlaceRequest fetchPlaceRequest = FetchPlaceRequest.builder(placeId, placeFields).build();
// FetchPlaceRequest fetchPlaceRequest = FetchPlaceRequest.newInstance(placeId, placeFields);
placesClient.fetchPlace(fetchPlaceRequest).addOnSuccessListener(new OnSuccessListener<FetchPlaceResponse>() {
@Override
public void onSuccess(FetchPlaceResponse fetchPlaceResponse) {
Place place = fetchPlaceResponse.getPlace();
Log.i("mytag", "Place found: " + place.getName());
Log.i("mytag", "Place found: " + place.getAddress());
//FETCH SELECTED PLACE LAT LNG
latLngOfPlace = place.getLatLng();
Log.i("mytag", "LAT: " + latLngOfPlace.latitude);
Log.i("mytag", "LNG: " + latLngOfPlace.longitude);
//ANIMATE CAMERA TO SELECTED LOCATION
if (latLngOfPlace != null) {
mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(latLngOfPlace, DEFAULT_ZOOM));
}
else{
Toast.makeText(MapsActivity.this, "unable to get location", Toast.LENGTH_SHORT).show();
}
}
}).addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
if (e instanceof ApiException) {
ApiException apiException = (ApiException) e;
apiException.printStackTrace();
int statusCode = apiException.getStatusCode();
Log.i("mytag", "place not found: " + e.getMessage());
Log.i("mytag", "status code: " + statusCode);
}
}
});
}
@Override
public void OnItemDeleteListener(int position, View v) {
}
});
问题是我无法搜索所有地方。它只预测一些地方而不是全部；通常可以使用谷歌地图搜索。 例如： 如果我尝试在我的城市搜索麦当劳，它只显示一个，而我们在我的城市有数十家麦当劳。
或任何其他餐厅或公共场所，它不会搜索其中任何一个。搜索非常有限。
但如果我使用 AutocompleteSupportFragment 实现 Places SDK，则搜索工作正常，如下所示：
//INITIALIZE PLACES API
Places.initialize(MapsActivity.this, getString(R.string.google_maps_api));
placesClient = Places.createClient(this);
// Initialize the AutocompleteSupportFragment.
AutocompleteSupportFragment autocompleteFragment = (AutocompleteSupportFragment)
getSupportFragmentManager().findFragmentById(R.id.autocomplete_fragment);
// Specify the types of place data to return.
autocompleteFragment.setPlaceFields(Arrays.asList(Place.Field.ID, Place.Field.NAME));
// Set up a PlaceSelectionListener to handle the response.
autocompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {
@Override
public void onPlaceSelected(Place place) {
// TODO: Get info about the selected place.
Log.i("tag", "Place: " + place.getName() + ", " + place.getId());
}
@Override
public void onError(Status status) {
// TODO: Handle the error.
Log.i("tag", "An error occurred: " + status);
}
});
我不明白我在以编程方式实现它时做错了什么。您的帮助将不胜感激。提前致谢。
