java - 如何从 Google Places API 中删除不需要的地点？

Question

我为我的应用程序创建了一个 Google Places API，它目前显示附近的所有地点，如医院、餐馆、学校等。我希望它只显示餐馆。是否可以？如果是这样，怎么办？非常感谢您的帮助。谢谢:)

Answer 1

place.getPlaceTypes() 返回一个整数列表，如果您想要查找餐厅类型，请检查它是否包含 Place.TYPE_RESTAURANT。您可以在 Place 类中获取以 TYPE_ 开头的类型值。

[编辑]在您的代码中:

final Place place = PlacePicker.getPlace(this, data);
List<Integer> types = place.getPlaceTypes();
for(Integer i : types){
    if (i == Place.TYPE_RESTAURANT){
           // its restaurant do something
        final CharSequence name = place.getName();
        final CharSequence address = place.getAddress();
        String attributions = (String) place.getAttributions();
        if (attributions == null) {
            attributions = "";
        }

        mName.setText(name);
        mAddress.setText(address);
        mAttributions.setText(Html.fromHtml(attributions));
    } 
}

您所描述的红色图标是一个标记，您可以将它们添加到 map 上。因此，在您的 onActivityResult 中，您会得到一个 Place (已在您的代码中显示)。地点包含名称和位置，使用它在 map 上显示标记，如下所示:

Marker markerPlace = map.addMarker(new MarkerOptions().position(place.getLatLng()).title(place.getName));

查看 map 标记的文档和相关文章。
