Question

預期結果：在autocomplete小部件中查詢返回嵌入式Google地圖片段中用標記指示的位置。

到目前爲止的代碼：

// Get the SupportMapFragment and request notification 
// when the map is ready to be used. 
SupportMapFragment mapFragment = (SupportMapFragment) getChildFragmentManager(). 
     findFragmentById(R.id.mapView); 
mapFragment.getMapAsync(this); 

PlaceAutocompleteFragment autocompleteFragment = (PlaceAutocompleteFragment) 
     getActivity().getFragmentManager().findFragmentById(R.id.place_autocomplete_fragment); 

EditText attributeText = (EditText)autocompleteFragment.getView().findViewById(R.id.place_autocomplete_search_input); 
attributeText.setHint("find your space!"); 
autocompleteFragment.getView().setBackgroundDrawable(getResources().getDrawable(R.drawable.gradient_search)); 

autocompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() { 

    @Override 
    public void onPlaceSelected(Place place) { 
     // TODO: Get info about the selected place. 
     Log.i(TAG, "Place: " + place.getName()); 
    } 

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

@Override 
public void onMapReady(GoogleMap googleMap) { 

// Customise the styling of the base map using a JSON object defined 
// in a raw resource file. 
googleMap.setMapStyle(
     MapStyleOptions.loadRawResourceStyle(
       getContext(), R.raw.style_json)); 

// adjust camera view 
LatLng kekistan = new LatLng(54.60651219, -9.931456); 
googleMap.addMarker(new MarkerOptions().position(kekistan) 
     .title("Kekistan City Centre")); 
googleMap.moveCamera(CameraUpdateFactory.newLatLng(kekistan)); 
googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(kekistan, 16)); 
}

首先，您需要保存在實例的GoogleMap的參考變量，並將其分配在中回調：

GoogleMap mMap; 

@Override 
public void onMapReady(GoogleMap googleMap) { 

    mMap = googleMap; 

    //........... 

} 

然後，你只需要得到的名稱和位置，然後放置標記：

autocompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() { 
    @Override 
    public void onPlaceSelected(Place place) { 
     Log.i(TAG, "Place: " + place.getName()); 
     String name = (String) place.getName(); 
     LatLng latLng = place.getLatLng(); 

     MarkerOptions markerOptions = new MarkerOptions(); 
     markerOptions.position(latLng); 
     markerOptions.title(name); 
     markerOptions.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_MAGENTA)); 
     mMap.addMarker(markerOptions); 

     //move map camera 
     mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(latLng,11)); 
    } 

    @Override 
    public void onError(Status status) { 
     Log.i(TAG, "An error occurred: " + status); 
    } 
});
