您可以简单地使用PlaceAutoCompleteFragment。
首先确保您使用的是最新版本的 Google Play 服务 (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'
然后在您的 xml 布局中包含 PlaceAutoCompleteFragment:
<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>
然后在你的 Activity 中设置一个监听器:
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;
}
}
运行此代码时,您会在 Google 地图上方看到自动完成栏:
当您点击自动完成栏时,它将如下所示:
然后,开始输入,并选择一个地点:
当您点击一个地点以选择它时,您将看到来自 PlaceSelectionListener 的日志:
D/Maps: Place selected: San Francisco
