我正在Android中制作一个简单的地方选择程序，问题是当我点击按钮时，地方选择器打开并在2 - 3秒后自动关闭......请帮忙！

MainActivity.java 

package com.example.akshay.myapplication;

import android.content.Intent;

import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;

import android.view.View;
import android.widget.Button;

import com.google.android.gms.maps.model.LatLngBounds;

public class MainActivity extends ActionBarActivity implements View.OnClickListener {

    Button b;
    private static final int PLACE_PICKER_REQUEST = 1;
    private static final LatLngBounds BOUNDS_MOUNTAIN_VIEW = new LatLngBounds(
            new LatLng(37.398160, -122.180831), new LatLng(37.430610, -121.972090));


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        b = (Button) findViewById((R.id.bOpenMap));
        b.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
            try {
                PlacePicker.IntentBuilder intentBuilder =
                        new PlacePicker.IntentBuilder();
                intentBuilder.setLatLngBounds(BOUNDS_MOUNTAIN_VIEW);
                Intent intent = intentBuilder.build(getApplicationContext());
                startActivityForResult(intent, PLACE_PICKER_REQUEST);
            } catch (GooglePlayServicesRepairableException e) {
                e.printStackTrace();
            } catch (GooglePlayServicesNotAvailableException e) {
                e.printStackTrace();
            }
        }

    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == PLACE_PICKER_REQUEST) {
            if (resultCode == RESULT_OK) {
                Place place = PlacePicker.getPlace(data, this);
                String toastMsg = String.format("Place: %s", place.getName());
                Toast.makeText(this, toastMsg, Toast.LENGTH_LONG).show();
            }
        }
    }
}

答案 0 :(得分：0)

我运行了您的代码和配置，并看到了您所看到的相同行为。

在将您的配置与我工作的配置进行比较后，我意识到问题在于您的AndroidManifest.xml中需要更改此设置：

android:name="com.google.android.maps.v2.API_KEY"

对此：

android:name="com.google.android.geo.API_KEY"

我回去并使用这两种配置进行了多次测试，以确保这是造成问题的原因。使用第一个配置，PlacePicker每次都会立即关闭。

使用com.google.android.geo.API_KEY，每次都能完美运作。

这也是您需要为Places API使用的the documentation州。

使用您的代码进行测试的结果，以及使其运行所需的一项修改：
