使用Google API時，如何在應用程序中獲得僅城市名稱而不是整個地址的輸出？

Question

即使用戶搜索城市中的任何地區，輸出也應該是城市名稱。

package com.example.rajat.location;

import android.content.Intent; import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.util.Log; import android.view.View; import android.widget.TextView;

import com.google.android.gms.common.GooglePlayServicesNotAvailableException; import com.google.android.gms.common.GooglePlayServicesRepairableException; import com.google.android.gms.common.api.Status; import com.google.android.gms.location.places.Place; import com.google.android.gms.location.places.ui.PlaceAutocomplete;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    /*
     * In this method, Start PlaceAutocomplete activity
     * PlaceAutocomplete activity provides--
     * a search box to search Google places
     */
    public void findPlace(View view) {
        try {
            Intent intent =
                    new PlaceAutocomplete
                            .IntentBuilder(PlaceAutocomplete.MODE_FULLSCREEN)
                            .build(this);
            startActivityForResult(intent, 1);
        } catch (GooglePlayServicesRepairableException e) {
            // TODO: Handle the error.
        } catch (GooglePlayServicesNotAvailableException e) {
            // TODO: Handle the error.
        }
    }

    // A place has been received; use requestCode to track the request.
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == 1) {
            if (resultCode == RESULT_OK) {
                // retrive the data by using getPlace() method.
                Place place = PlaceAutocomplete().getPlace(this, data);
                Log.e("Tag", "Place: " + place.getAddress() + place.getPhoneNumber());

                ((TextView) findViewById(R.id.searched_address))
                        .setText(place.getName()+",\n"+
                                place.getAddress() +"\n" + place.getPhoneNumber());

            } else if (resultCode == PlaceAutocomplete.RESULT_ERROR) {
                Status status = PlaceAutocomplete.getStatus(this, data);
                // TODO: Handle the error.
                Log.e("Tag", status.getStatusMessage());

            } else if (resultCode == RESULT_CANCELED) {
                // The user canceled the operation.
            }
        }
    } }

您需要使用特定於Google Places API的密鑰來從JSON響應對象中檢索城市名稱。

此鏈接顯示您返回的JSON響應（鍵值對） https://developers.google.com/places/web-service/details

檢查您的JSON響應對象（我相信這是您的“ Place”對象）。

在這行代碼上運行調試語句。 Place place = PlaceAutocomplete（）。getPlace（this，data）;

知道城市的鍵后，獲取城市值，然后僅用城市值填充UI。
