API de Android Places

Ejemplo de uso del selector de lugar

Place Picker es un widget de interfaz de usuario realmente simple proporcionado por la API de Places. Proporciona un mapa incorporado, ubicación actual, lugares cercanos, capacidades de búsqueda y autocompletar.

Este es un ejemplo de uso del widget de la interfaz de usuario del Selector de lugares.

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()));
        }
    }
}

Obtener lugares actuales utilizando la API de lugares

Puede obtener la ubicación actual y los lugares locales de usuario utilizando la API de Google Places .

Primero, debe llamar al método PlaceDetectionApi.getCurrentPlace() para recuperar negocios locales u otros lugares. Este método devuelve un objeto PlaceLikelihoodBuffer que contiene una lista de objetos PlaceLikelihood . Luego, puede obtener un objeto Place llamando al método PlaceLikelihood.getPlace() .

Importante: debe solicitar y obtener el permiso ACCESS_FINE_LOCATION para permitir que su aplicación acceda a información de ubicación precisa.

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());
}

Integración automática de lugares

La función de autocompletar en la API de Google Places para Android proporciona predicciones de lugar al usuario. Mientras el usuario escribe en el cuadro de búsqueda, autocompletar muestra los lugares de acuerdo con las consultas del usuario.

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();
        }
    });

}

}

           }
        }
    }

Configuración de filtros de tipo de lugar para PlaceAutocomplete

En algunos casos, es posible que desee limitar los resultados que muestra PlaceAutocompletar a un país específico o tal vez mostrar solo las Regiones. Esto se puede lograr estableciendo un AutocompleteFilter en la intención. Por ejemplo, si deseo buscar solo lugares de tipo REGIÓN y que pertenezcan solo a la India, haría lo siguiente:

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>

El PlaceAutocomplete se iniciará automáticamente y, a continuación, puede seleccionar un lugar de los resultados que solo serán del tipo REGIÓN y que solo pertenecerán al país especificado. La intención también se puede lanzar con el clic de un botón.
