Google places API返回单个类型"car_repair“

Question

我正在使用Google places API，它会返回我所在位置的所有位置。然而，我只想让它返回一个“汽车维修”的类型，我想我差不多就有了，但我遗漏了一些东西，如果有人能把我引向正确的方向，那就太好了:)

我到目前为止的代码PlacPickerActivity

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.text.Html;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

import com.google.android.gms.common.GooglePlayServicesNotAvailableException;
import com.google.android.gms.common.GooglePlayServicesRepairableException;

import com.google.android.gms.location.places.ui.PlacePicker;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.LatLngBounds;


public class PlacePickerActivity extends AppCompatActivity {

    private static final int PLACE_PICKER_REQUEST = 1;
    String url="https://maps.googleapis.com/maps/api/place/textsearch/json?type=car_repair&key=AIzaSyBKsTtLyMBQH8mhvbknJ4MvZwACotmeYO0";

    private TextView mName;
    private TextView mAddress;
    private TextView mAttributions;
    private TextView mNumber;
    private static final LatLngBounds Sligo = new LatLngBounds(
            new LatLng(54.27, -8.47), new LatLng(54.27, -8.47));

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_place_picker);
        mName = (TextView) findViewById(R.id.textView);
        mAddress = (TextView) findViewById(R.id.textView2);
        mAttributions = (TextView) findViewById(R.id.textView3);
        mNumber = (TextView) findViewById(R.id.textView4);
        Button pickerButton = (Button) findViewById(R.id.pickerButton);
        pickerButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                try {
                    PlacePicker.IntentBuilder intentBuilder =
                            new PlacePicker.IntentBuilder();
                    intentBuilder.setLatLngBounds(Sligo);

                    Intent intent = intentBuilder.build(PlacePickerActivity.this);
                    startActivityForResult(intent, PLACE_PICKER_REQUEST);

                } catch (GooglePlayServicesRepairableException
                        | GooglePlayServicesNotAvailableException e) {
                    e.printStackTrace();
                }
            }
        });
    }

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

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

            final Place place = PlacePicker.getPlace(this, data);
            final CharSequence name = place.getName();
            final CharSequence address = place.getAddress();
            final CharSequence formatted_phone_number = place.getPhoneNumber();
            String attributions = (String) place.getAttributions();
            if (attributions == null) {
                attributions = "";
            }

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


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

}

当我在PC上的浏览器中输入URL时，它会返回我所在区域的所有类型"car_repair“，因此我的API键可以正常工作

Answer 1

尝试使用类似如下的查询: Location is in format latitude，longitude...and小心是"types“而不是type。

https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=54.27,-8.47&radius=1000&types=car_repair&key=AddYourOwnKeyHere

Answer 2

因为此API返回作用域中的place类型。有一种方法可能会改善结果，但仍然不是最优的，那就是setLatLngBounds.The link is https://developers.google.com/android/reference/com/google/android/gms/location/places/ui/PlacePicker.IntentBuilder#public-method-summary我以前试过这个接口，发现它在某种程度上完全是一团糟。例如，如果您要查找大学内部的餐厅，此接口不仅会返回餐厅，还会返回许多其他类型，如University。设置一个界限可能是好的，但如果你只使用API，仍然会得到恼人的结果。如果你只想要car-repair的类型，我建议你写一个过滤器来过滤其他类型，只保留汽车维修类型和相关信息。

这是我为你准备的，希望对你有所帮助

 // A class to store your results
 public class Place {
     private String icon;
     private Double latitude;

    public void setIcon(String icon) {
        this.icon=icon;
    }

    public void setLatitude(Double latitude) {
        this.latitude=latitude;
    }

    // .....
}

// Utility class to keep things simple
public class Functions {

     public static JSONObject convertInputStreamToJSONObject(InputStream inputStream)
        throws JSONException, IOException 
   {
       BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
       String line = "";
       String result = "";
       while ((line = bufferedReader.readLine()) != null)
           result += line;

       inputStream.close();
       return new JSONObject(result);

   }

   public static ArrayList<Place> parsePlacesFromJson(JSONObject datos) throws JSONException {

       List<Place> placesList = new ArrayList<>();

       // in your case this must be "results" I think
       final int LIST_LENGTH = datos.getJSONArray("results").length();
       //final int LIST_LENGTH = datos.getJSONArray("nameOfTheJsonMainArray").length();

       Log.d("Length", String.valueOf(LIST_LENGTH));


       // For every element in the list
       for(int i = 0; i < LIST_LENGTH; i++) {

           // Instance of a new Place
           Place place = new Place();

           // Get data as needed, this represents one place
           JSONObject obj = datos.getJSONArray("results").getJSONObject(i);

           Double latitude = obj.getJSONObject("geometry").getJSONObject("location").getDouble("lat");
           String icon = obj.getString("icon");

           place.setLatitude(latitude);
           place.setIcon(icon);
           //....
           placesList.add(place)

       }

       return placesList;
   }
 }

// The google places reader class
public class ApiReader {


   private static final String TAG = "API_READER";
   Context context;
   View v; 

   public ApiReader(Context context, View v) {

   // Method to be called 
   public void getCarRepairs() throws IOException {
       URL url = new URL(String.format(ENDPOINT, APIKEY));
       new GetPlaces().execute(url);
   }




   // Inner asyctask class 
   private class GetPlaces extends AsyncTask<URL, Integer, List<Place>> {
       List<Place> lista;
       @Override
       protected List<Place> doInBackground(URL... params) {
           JSONObject datos;
           URL url = params[0];
           HttpURLConnection urlConnection = null;


           try {

               datos = Functions.convertInputStreamToJSONObject(in);
               Log.i(TAG, datos.toString());

                 // De los datos obtenemos un objeto Place

               lista  = Functions.parsePlacesFromJson(datos);
               Log.i(TAG, "" + lista.toString());
               Log.i(TAG, "Went into try was OK.");

           } catch (Exception e) {

           } finally {
               urlConnection.disconnect();

           }

           return lista;
       }


       // This method it gets what the "doInBackGround" returns
       protected void onPostExecute(List<Place> placesList) {

           if(placesList != null) {

               // Do whatever with the list of places
               //Functions.updateView(v, placesList);

           }
       }
   }

 }

 // And to make things work in yout activity just do like this

        ApiReader api = new ApiReader(this, findViewById(R.id.mainLayout));

        try {
            api.getCarRepairs();
        } catch (IOException e) {
            e.printStackTrace();
        }

享受吧!！
