hirxn45624 回答：在地图中放置AutoCompleteTextView

我自己使用另一种方法解决了问题，该方法是developers.google.com在文档中使用的新方法。我使用第一种方法添加为自动完成小部件。

在我的活动的onCreate我初始化的地方实例上。

Places.initialize(getApplicationContext(),getResources().getString(R.string.google_maps_key));
PlacesClient placesClient = Places.createClient(activity);

再次在onCreate上初始化并声明我的pickupFragment并将其与侦听器绑定。

pickupFragment = (AutocompleteSupportFragment) getSupportFragmentManager().findFragmentById(R.id.pickupFragment);
pickupFragment.setCountry("PK");
pickupFragment.setPlaceFields(Arrays.asList(Place.Field.ID,Place.Field.NAME,Place.Field.ADDRESS,Place.Field.LAT_LNG));
pickupFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {
        @Override
        public void onPlaceSelected(Place place) {
            // TODO: Get info about the selected place.
            Log.e(TAG,"Place: " + place.getName() + "," + place.getId() + "," + place.getLatLng());
        }

        @Override
        public void onError(Status status) {
            // TODO: Handle the error.
            Log.e(TAG,"An error occurred: " + status);
        }
    });

并在我的xml中使用了这段代码

<fragment
 android:id="@+id/pickupFragment"
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:name="com.google.android.libraries.places.widget.AutocompleteSupportFragment" />

我为我的pickupFragment和dropoffFragment都做了。
