使用Google Places API安装Android PlaceFilter

Question

我正在尝试使用Google Places API,我想将搜索过滤为仅限于健身房类型.

我使用的是https://developers.google.com/places/上提供的代码

public void onPickButtonClick(View v) {
// Construct an intent for the place picker
try {
    PlacePicker.IntentBuilder intentBuilder =
        new PlacePicker.IntentBuilder();
    Intent intent = intentBuilder.build(this);
    // Start the intent by requesting a result,
    // identified by a request code.
    startActivityForResult(intent, REQUEST_PLACE_PICKER);

} catch (GooglePlayServicesRepairableException e) {
    // ...
} catch (GooglePlayServicesNotAvailableException e) {
    // ...
}
}

@Override
protected void onActivityResult(int requestCode,
    int resultCode, Intent data) {

if (requestCode == REQUEST_PLACE_PICKER
    && resultCode == Activity.RESULT_OK) {

    // The user has selected a place. Extract the name and address.
    final Place place = PlacePicker.getPlace(data, this);

    final CharSequence name = place.getName();
    final CharSequence address = place.getAddress();
    String attributions = PlacePicker.getAttributions(data);
    if (attributions == null) {
        attributions = "";
    }

    mViewName.setText(name);
    mViewAddress.setText(address);
    mViewAttributions.setText(Html.fromHtml(attributions));

} else {
    super.onActivityResult(requestCode, resultCode, data);
}
}

我试图做的是创建一个像下面这样的过滤器,并以某种方式将(placeFilter)添加到intent.

PlacePicker.IntentBuilder intentBuilder = new PlacePicker.IntentBuilder();
PlaceFilter placeFilter;
ArrayList<String> restictToGyms = new ArrayList<>();
restictToGyms.add("44");
placeFilter = new PlaceFilter(false, restictToGyms);
intent.SOMEHOWADD(placeFilter);
Intent intent = intentBuilder.build(this);

但我不确定如何将此过滤器添加到意图中.事实上,我不确定这是否是正确的做法.任何指针将不胜感激.谢谢!

我一直想做同样的事情。不幸的是，这似乎不可能——PlaceFilter 使用的是地点 ID，而不是类型。PlaceFilter 类是最终类，因此无法扩展（我讨厌 API 编写者将类设为最终类，几乎没有理由这样做）。您需要实际进行调用并在结果返回后通过循环进行过滤。
