我在我的活动中使用autoComplete Places API和google maps。我想删除自动完成Places API下拉列表中显示的徽标Powered by google，但我发现只有javascript的解决方案不适用于Android。

最后我实施如下：
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();
}
}
}
这是活动：
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.");
}
}
答案 1 :(得分：0)
如果您的应用程序在Google Maps上显示Places API中的数据，则将包含Google徽标，并且不得更改。
如果您的应用在没有Google Map的页面或视图上显示Places API数据，则必须显示带有该数据的“由Google提供支持”图片。
