如何在“查找当前位置”中获取以后可以单独选择的响应响应

Question

我需要做一个活动，允许用户点击getLocation按钮，该按钮又根据可能性分数返回地点列表。来自FindCurrentPlaceResponse的响应返回20个项目，我希望它们以列表或卡片视图的形式出现，用户最终从中选择最合适的位置。如何使响应返回可放入可点击列表中的各个位置？我已经遵循并完全使用谷歌地点文档 https://github.com/googlemaps/android-places-demos 我的活动这是文档中将列表转换为单个字符串的确切代码@RequiresPermission(allOf = {ACCESS_FINE_LOCATION, ACCESS_WIFI_STATE})private void findCurrentPlaceWithPermissions() {setLoading(true);    FindCurrentPlaceRequest currentPlaceRequest = FindCurrentPlaceRequest.newInstance(getPlaceFields());    Task<FindCurrentPlaceResponse> currentPlaceTask = placesClient.findCurrentPlace(currentPlaceRequest);    currentPlaceTask.addOnSuccessListener(        (response) ->            responseView.setText(StringUtil.stringify(response, isDisplayRawResultsChecked())));    currentPlaceTask.addOnFailureListener(        (exception) -> {          exception.printStackTrace();          responseView.setText(exception.getMessage());        });    currentPlaceTask.addOnCompleteListener(task -> setLoading(false));  }

Answer 1

字符串化就是这样做的。回应本身已经是“回应”。你可能需要一个带有回调的接口才能将结果添加到磁贴列表中。

// The callback interface

interface MyCallback {

void callbackCall(List<String> response);

}

// The class that takes the callback

class Worker {

MyCallback callback;

void onEvent(List<String> response) {

  callback.callbackCall(response);

   }

}

// Option 1: MainActivity or where the list is

class Callback implements MyCallback {

  void callbackCall() {

   // callback code goes here

   // update your adaptor 

   }

 }

worker.callback = new Callback();

// Option 2:

worker.callback = new MyCallback() {

void callbackCall(List<String> results ) {

  // callback code goes here

   }

};
