Android Places API

작업 공간 선택기 사용 예제

장소 선택 도구는 Places API에서 제공하는 매우 간단한 UI 위젯입니다. 내장지도, 현재 위치, 주변 장소, 검색 기능 및 자동 완성 기능을 제공합니다.

장소 선택기 UI 위젯의 샘플 사용법입니다.

private static int PLACE_PICKER_REQUEST = 1;

private TextView txtPlaceName;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_place_picker_sample);

    txtPlaceName = (TextView) this.findViewById(R.id.txtPlaceName);
    Button btnSelectPlace = (Button) this.findViewById(R.id.btnSelectPlace);
    btnSelectPlace.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            openPlacePickerView();
        }
    });

}

private void openPlacePickerView(){
    PlacePicker.IntentBuilder builder = new PlacePicker.IntentBuilder();
    try {
        startActivityForResult(builder.build(this), PLACE_PICKER_REQUEST);
    } catch (GooglePlayServicesRepairableException e) {
        e.printStackTrace();
    } catch (GooglePlayServicesNotAvailableException e) {
        e.printStackTrace();
    }
}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == PLACE_PICKER_REQUEST) {
        if (resultCode == RESULT_OK) {
            Place place = PlacePicker.getPlace(this, data);
            Log.i(LOG_TAG, String.format("Place Name : %s", place.getName()));
            Log.i(LOG_TAG, String.format("Place Address : %s", place.getAddress()));
            Log.i(LOG_TAG, String.format("Place Id : %s", place.getId()));

            txtPlaceName.setText(String.format("Place : %s - %s" , place.getName() , place.getAddress()));
        }
    }
}

Places API를 사용하여 현재 위치 가져 오기

Google 지역 정보 API를 사용하여 사용자의 현재 위치 및 지역 정보를 가져올 수 있습니다.

먼저 지역 비즈니스 나 다른 장소를 검색하려면 PlaceDetectionApi.getCurrentPlace() 메소드를 호출해야합니다. 이 방법은 반환 PlaceLikelihoodBuffer 목록이 포함되어 객체 PlaceLikelihood 객체. 그런 다음 PlaceLikelihood.getPlace() 메서드를 호출하여 Place 객체를 가져올 수 있습니다.

중요 : 앱이 정확한 위치 정보에 액세스 할 수있게하려면 ACCESS_FINE_LOCATION 권한을 요청하여 확보해야합니다.

private static final int PERMISSION_REQUEST_TO_ACCESS_LOCATION = 1;

private TextView txtLocation;
private GoogleApiClient googleApiClient;

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_location);

    txtLocation = (TextView) this.findViewById(R.id.txtLocation);
    googleApiClient = new GoogleApiClient.Builder(this)
            .addApi(Places.GEO_DATA_API)
            .addApi(Places.PLACE_DETECTION_API)
            .enableAutoManage(this, this)
            .build();

    getCurrentLocation();
}

private void getCurrentLocation() {
    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        Log.e(LOG_TAG, "Permission is not granted");

        ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.ACCESS_FINE_LOCATION},PERMISSION_REQUEST_TO_ACCESS_LOCATION);
        return;
    }

    Log.i(LOG_TAG, "Permission is granted");
    
    PendingResult<PlaceLikelihoodBuffer> result = Places.PlaceDetectionApi.getCurrentPlace(googleApiClient, null);
    result.setResultCallback(new ResultCallback<PlaceLikelihoodBuffer>() {
        @Override
        public void onResult(PlaceLikelihoodBuffer likelyPlaces) {
            Log.i(LOG_TAG, String.format("Result received : %d " , likelyPlaces.getCount() ));
            StringBuilder stringBuilder = new StringBuilder();

            for (PlaceLikelihood placeLikelihood : likelyPlaces) {
                stringBuilder.append(String.format("Place : '%s' %n",
                        placeLikelihood.getPlace().getName()));
            }
            likelyPlaces.release();
            txtLocation.setText(stringBuilder.toString());
        }
    });
}

@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case PERMISSION_REQUEST_TO_ACCESS_LOCATION: {
            // If the request is cancelled, the result arrays are empty.
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                getCurrentLocation();
            } else {
                // Permission denied, boo!
                // Disable the functionality that depends on this permission.
            }
            return;
        }

        // Add further 'case' lines to check for other permissions this app might request.
    }
}

@Override
public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
    Log.e(LOG_TAG, "GoogleApiClient connection failed: " + connectionResult.getErrorMessage());
}

장소 자동 완성 통합

Android 용 Google Places API의 자동 완성 기능은 사용자에게 장소 예측을 제공합니다. 사용자가 검색 창에 입력하는 동안 자동 완성 기능은 사용자의 검색어에 따라 장소를 표시합니다.

AutoCompleteActivity.java

private TextView txtSelectedPlaceName;

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_autocomplete);

    txtSelectedPlaceName = (TextView) this.findViewById(R.id.txtSelectedPlaceName);

    PlaceAutocompleteFragment autocompleteFragment = (PlaceAutocompleteFragment)
            getFragmentManager().findFragmentById(R.id.fragment_autocomplete);

    autocompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {
        @Override
        public void onPlaceSelected(Place place) {
            Log.i(LOG_TAG, "Place: " + place.getName());
            txtSelectedPlaceName.setText(String.format("Selected places : %s  - %s" , place.getName(), place.getAddress()));
        }

        @Override
        public void onError(Status status) {
            Log.i(LOG_TAG, "An error occurred: " + status);
            Toast.makeText(AutoCompleteActivity.this, "Place cannot be selected!!", Toast.LENGTH_SHORT).show();
        }
    });

}

}

activity_autocomplete.xml

<fragment
    android:id="@+id/fragment_autocomplete"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:name="com.google.android.gms.location.places.ui.PlaceAutocompleteFragment"
    />



<TextView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/txtSelectedPlaceName"
    android:layout_margin="20dp"
    android:padding="15dp"
    android:hint="@string/txt_select_place_hint"
    android:textSize="@dimen/place_autocomplete_prediction_primary_text"/>

Google 자동 완성 활동을 두 개 이상 추가하는 중입니다.

 public static final int PLACE_AUTOCOMPLETE_FROM_PLACE_REQUEST_CODE=1;
   public static final int PLACE_AUTOCOMPLETE_TO_PLACE_REQUEST_CODE=2;

fromPlaceEdit.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {

                    try {
                      //Do your stuff from place
                        startActivityForResult(intent, PLACE_AUTOCOMPLETE_FROM_PLACE_REQUEST_CODE);

                    } catch (GooglePlayServicesRepairableException e) {
                        // TODO: Handle the error.
                    } catch (GooglePlayServicesNotAvailableException e) {
                        // TODO: Handle the error.
                    }
                }
            });
toPlaceEdit.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                try {

                    startActivityForResult(intent, PLACE_AUTOCOMPLETE_TO_PLACE_REQUEST_CODE);

                } catch (GooglePlayServicesRepairableException e) {

                } catch (GooglePlayServicesNotAvailableException e) {
                    // TODO: Handle the error.
                }
            }
        });
@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
       if (requestCode == PLACE_AUTOCOMPLETE_FROM_PLACE_REQUEST_CODE) {
           if (resultCode == RESULT_OK) {
              //Do your ok >from place< stuff here
           } else if (resultCode == PlaceAutocomplete.RESULT_ERROR) {
              //Handle your error >from place<
           } else if (resultCode == RESULT_CANCELED) {
               // The user canceled the operation.
           }
       } else if (requestCode == PLACE_AUTOCOMPLETE_TO_PLACE_REQUEST_CODE) {
           if (resultCode == RESULT_OK) {
              //Do your ok >to place< stuff here
           } else if (resultCode == PlaceAutocomplete.RESULT_ERROR) {
              //Handle your error >to place<
           } else if (resultCode == RESULT_CANCELED) {
               // The user canceled the operation.
           }
        }
    }

PlaceAutocomplete에 대한 장소 유형 필터 설정

일부 시나리오에서는 PlaceAutocomplete 가 특정 국가에 표시 한 결과를 좁히거나 지역 만 표시 할 수 있습니다. 자동 완성 필터 를 의도로 설정하면이 작업을 수행 할 수 있습니다. 예를 들어, REGION 유형의 장소 만보고 인도에만 속하는 경우 다음을 수행합니다.

MainActivity.java

public class MainActivity extends AppComatActivity {
    
    private static final int PLACE_AUTOCOMPLETE_REQUEST_CODE = 1;
    private TextView selectedPlace;
    
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        selectedPlace = (TextView) findViewById(R.id.selected_place);
        try {
            AutocompleteFilter typeFilter = new AutocompleteFilter.Builder()
                    .setTypeFilter(AutocompleteFilter.TYPE_FILTER_REGIONS)
                    .setCountry("IN")
                    .build();

            Intent intent =
                    new PlaceAutocomplete.IntentBuilder(PlaceAutocomplete.MODE_FULLSCREEN)
                            .setFilter(typeFilter)
                            .build(this);
            startActivityForResult(intent, PLACE_AUTOCOMPLETE_REQUEST_CODE);

        } catch (GooglePlayServicesRepairableException
                | GooglePlayServicesNotAvailableException e) {
            e.printStackTrace();
        }
}

protected void onActivityResult(int requestCode,
                                int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == PLACE_AUTOCOMPLETE_REQUEST_CODE && resultCode == Activity.RESULT_OK) {
        final Place place = PlacePicker.getPlace(this, data);
        selectedPlace.setText(place.getName().toString().toUpperCase());
    } else {
        Toast.makeText(MainActivity.this, "Could not get location.", Toast.LENGTH_SHORT).show();
    }
}

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
          android:orientation="vertical"
          android:layout_width="match_parent"
          android:layout_height="match_parent">

<TextView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/selected_place"/>

</LinearLayout>

PlaceAutocomplete 가 자동으로 실행되면 결과에서 REGION 유형의 장소 만 선택할 수 있으며 지정된 국가에만 속합니다. 인 텐트는 버튼 클릭만으로 시작할 수도 있습니다.
