android - 从 PlaceAutocomplete 中删除 "Powered by google"

Question

我在我的 Activity 中使用了 autoComplete Places API 和 google maps。我想删除出现在 autoComplete Places API 下拉列表中的 Logo Powered by google 但我只找到了 javascript 中的解决方案，不适用于 android。

Answer 1

最后我实现如下:

这是适配器

public class PlaceArrayAdapter extends ArrayAdapter<PlaceArrayAdapter.PlaceAutocomplete> implements Filterable {
    private static final String TAG = "PlaceArrayAdapter";
    private GoogleApiClient mGoogleApiClient;
    private AutocompleteFilter mPlaceFilter;
    private LatLngBounds mBounds;
    private ArrayList<PlaceAutocomplete> mResultList;

    /**
     * Constructor
     *
     * @param context  Context
     * @param resource Layout resource
     * @param bounds   Used to specify the search bounds
     * @param filter   Used to specify place types
     */
    public PlaceArrayAdapter(Context context, int resource, LatLngBounds bounds, AutocompleteFilter filter) {
        super(context, resource);
        mBounds = bounds;
        mPlaceFilter = filter;
    }

    public void setGoogleApiClient(GoogleApiClient googleApiClient) {
        if (googleApiClient == null || !googleApiClient.isConnected()) {
            mGoogleApiClient = null;
        } else {
            mGoogleApiClient = googleApiClient;
        }
    }

    @Override
    public int getCount() {
        return mResultList.size();
    }

    @Override
    public PlaceAutocomplete getItem(int position) {
        return mResultList.get(position);
    }

    private ArrayList<PlaceAutocomplete> getPredictions(CharSequence constraint) {
        if (mGoogleApiClient != null) {
            Log.i(TAG, "Executing autocomplete query for: " + constraint);
            PendingResult<AutocompletePredictionBuffer> results =
                    Places.GeoDataApi
                            .getAutocompletePredictions(mGoogleApiClient, constraint.toString(),
                                    mBounds, mPlaceFilter);
            // Wait for predictions, set the timeout.
            AutocompletePredictionBuffer autocompletePredictions = results
                    .await(60, TimeUnit.SECONDS);
            final Status status = autocompletePredictions.getStatus();
            if (!status.isSuccess()) {
                Toast.makeText(getContext(), "Error: " + status.toString(),
                        Toast.LENGTH_SHORT).show();
                Log.e(TAG, "Error getting place predictions: " + status
                        .toString());
                autocompletePredictions.release();
                return null;
            }

            Log.i(TAG, "Query completed. Received " + autocompletePredictions.getCount()
                    + " predictions.");
            Iterator<AutocompletePrediction> iterator = autocompletePredictions.iterator();
            ArrayList resultList = new ArrayList<>(autocompletePredictions.getCount());
            while (iterator.hasNext()) {
                AutocompletePrediction prediction = iterator.next();
                resultList.add(new PlaceAutocomplete(prediction.getPlaceId(),
                        prediction.getDescription()));
            }
            // Buffer release
            autocompletePredictions.release();
            return resultList;
        }
        Log.e(TAG, "Google API client is not connected.");
        return null;
    }

    @Override
    public Filter getFilter() {
        Filter filter = new Filter() {
            @Override
            protected FilterResults performFiltering(CharSequence constraint) {
                FilterResults results = new FilterResults();
                if (constraint != null) {
                    // Query the autocomplete API for the entered constraint
                    mResultList = getPredictions(constraint);
                    if (mResultList != null) {
                        // Results
                        results.values = mResultList;
                        results.count = mResultList.size();
                    }
                }
                return results;
            }

            @Override
            protected void publishResults(CharSequence constraint, FilterResults results) {
                if (results != null && results.count > 0) {
                    // The API returned at least one result, update the data.
                    notifyDataSetChanged();
                } else {
                    // The API did not return any results, invalidate the data set.
                    notifyDataSetInvalidated();
                }
            }
        };
        return filter;
    }

    class PlaceAutocomplete {

        public CharSequence placeId;
        public CharSequence description;

        PlaceAutocomplete(CharSequence placeId, CharSequence description) {
            this.placeId = placeId;
            this.description = description;
        }

        @Override
        public String toString() {
            return description.toString();
        }
    }
}

这是 Activity :

public class FindLocationByTextActivity extends AppCompatActivity implements OnMapReadyCallback, GoogleApiClient.OnConnectionFailedListener, GoogleApiClient.ConnectionCallbacks {

    private static final int GOOGLE_API_CLIENT_ID = 0;
    private GoogleApiClient mGoogleApiClient;
    private PlaceArrayAdapter mPlaceArrayAdapter;
    private AutoCompleteTextView mAutocompleteTextView;
    private static final LatLngBounds BOUNDS_MOUNTAIN_VIEW = new LatLngBounds(new LatLng(37.398160, -122.180831), new LatLng(37.430610, -121.972090));

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



        mGoogleApiClient = new GoogleApiClient.Builder(FindLocationByTextActivity.this)
                .addApi(Places.GEO_DATA_API)
                .enableAutoManage(this, GOOGLE_API_CLIENT_ID, this)
                .addConnectionCallbacks(this)
                .build();
        mAutocompleteTextView = (AutoCompleteTextView) findViewById(R.id.place_autocomplete_text_view);
        mAutocompleteTextView.setThreshold(2);
        mAutocompleteTextView.setOnItemClickListener(mAutocompleteClickListener);
        mPlaceArrayAdapter = new PlaceArrayAdapter(this, android.R.layout.simple_list_item_1, BOUNDS_MOUNTAIN_VIEW, null);
        mAutocompleteTextView.setAdapter(mPlaceArrayAdapter);

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {

        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_location, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();


        return super.onOptionsItemSelected(item);
    }

    private AdapterView.OnItemClickListener mAutocompleteClickListener
            = new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            final PlaceArrayAdapter.PlaceAutocomplete item = mPlaceArrayAdapter.getItem(position);
            final String placeId = String.valueOf(item.placeId);
            Log.i("Location", "Selected: " + item.description);
            PendingResult<PlaceBuffer> placeResult = Places.GeoDataApi
                    .getPlaceById(mGoogleApiClient, placeId);
            placeResult.setResultCallback(mUpdatePlaceDetailsCallback);
            Log.i("Location", "Fetching details for ID: " + item.placeId);
        }
    };

    private ResultCallback<PlaceBuffer> mUpdatePlaceDetailsCallback
            = new ResultCallback<PlaceBuffer>() {
        @Override
        public void onResult(PlaceBuffer places) {
            if (!places.getStatus().isSuccess()) {
                Log.e("Location", "Place query did not complete. Error: " +
                        places.getStatus().toString());
                return;
            }
            // Selecting the first object buffer.
            final Place place = places.get(0);

            Log.i("name", place.getName().toString());
            Log.i("coordinates", place.getLatLng().toString());
        }
    };

    @Override
    public void onConnected(Bundle bundle) {
        mPlaceArrayAdapter.setGoogleApiClient(mGoogleApiClient);
        Log.i("Location", "Google Places API connected.");

    }

    @Override
    public void onConnectionFailed(ConnectionResult connectionResult) {
        Log.e("Location", "Google Places API connection failed with error code: "
                + connectionResult.getErrorCode());

        Toast.makeText(this,
                "Google Places API connection failed with error code:" +
                        connectionResult.getErrorCode(),
                Toast.LENGTH_LONG).show();
    }

    @Override
    public void onConnectionSuspended(int i) {
        mPlaceArrayAdapter.setGoogleApiClient(null);
        Log.e("Location", "Google Places API connection suspended.");
    }

}
