问题描述
我正在创建基于地方搜索的应用。我想知道如何将搜索栏添加到我的Google地图中,用户可以在其中选择地点,并且可以捕捉用户选择的内容。
我尝试在用户界面中显示在Google地图上方显示的自动完成搜索框。 您可以简单地使用一个
当您点击自动完成栏,它将如下所示:
然后,开始输入,然后选择一个地方:
当你点击一个地方选择它时,你会看到来自PlaceSelectionListener的日志:
D /地图:选择地点:旧金山
I'm creating an app based on places search. I would like to know how can I add a search bar into my Google Map, where the user can select a Place, and I can capture what the user chose.
I'm trying to include an autocomplete Search Box that is displayed above the Google Map in the UI.
You can simply use a PlaceAutoCompleteFragment.
First ensure that you're using the latest version of Google Play Services (Version 8.4.0 and up includes the PlaceAutoCompleteFragment class):
compile 'com.google.android.gms:play-services-maps:11.0.2'
compile 'com.google.android.gms:play-services-location:11.0.2'
compile 'com.google.android.gms:play-services-places:11.0.2'
Then include the PlaceAutoCompleteFragment in your xml layout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MapsActivity"
android:orientation="vertical"
android:weightSum="1">
<fragment
android:id="@+id/place_autocomplete"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:name="com.google.android.gms.location.places.ui.PlaceAutocompleteFragment"
/>
<fragment
android:id="@+id/map"
class="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
Then set up a listener in your Activity:
import com.google.android.gms.common.api.Status;
import com.google.android.gms.location.places.Place;
import com.google.android.gms.location.places.ui.PlaceAutocompleteFragment;
import com.google.android.gms.location.places.ui.PlaceSelectionListener;
public class MapsActivity extends AppCompatActivity implements OnMapReadyCallback {
private GoogleMap mMap;
PlaceAutocompleteFragment placeAutoComplete;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
placeAutoComplete = (PlaceAutocompleteFragment) getFragmentManager().findFragmentById(R.id.place_autocomplete);
placeAutoComplete.setOnPlaceSelectedListener(new PlaceSelectionListener() {
@Override
public void onPlaceSelected(Place place) {
Log.d("Maps", "Place selected: " + place.getName());
}
@Override
public void onError(Status status) {
Log.d("Maps", "An error occurred: " + status);
}
});
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
}
@Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
}
}
When you run this code, you'll see the AutoComplete bar above the Google Map:
When you click on the AutoComplete bar, it will look like this:
Then, start typing, and select a Place:
When you tap on a place to select it, you will see the log from the PlaceSelectionListener:
D/Maps: Place selected: San Francisco
