即使用户搜索城市中的任何地点，输出也应该是城市的名称。

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.
            }
        }
    } }

您需要使用特定于Google Places API的密钥才能从JSON响应对象中检索城市名称。

此链接显示您要回复的JSON响应（键值对） https://developers.google.com/places/web-service/details

检查您的JSON响应对象（我认为是您的＆＃34; Place＆＃34;对象）。

在这行代码上运行调试语句。 Place place = PlaceAutocomplete（）。getPlace（this，data）;

知道City的键后，抓住City值并仅使用City值填充UI。

在使用Google API时，如何才能将输出视为我的应用中的城市名称而不是整个地址？
