我是谷歌地图的新手，因此很多事情对我来说还不够清楚。所以我期待一些专家在这方面的指导。我阅读了本指南并做了它所说的一切。我使用谷歌地图 api v2 并得到一个地图键。然后我按照该链接创建一个示例项目并选择目标版本 android 2.2（在运行项目时）。但是在运行 eclipse android 模拟器中的示例后出现错误列表。我的logcat视图显示：

</manifest>

我的main.xml是：

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/map"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  class="com.google.android.gms.maps.MapFragment"/>

我的activity.java是：

package com.googleMapApp;

import android.app.Activity;
import android.os.Bundle;


public class LocationProfileManagerActivity extends Activity {
    /** Called when the activity is first created. */
    //private GoogleMap map;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        //map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();

     }
}

很抱歉这个冗长的描述，但我想告诉你我做了什么。我认为作为一个新手，我在这种方式上犯了很多错误。所以我希望有人会指导我。

您正在使用仅在以后的 API 中可用的功能，即Fragment. 如果要编译支持 2.2，则需要在项目中包含支持库。您还必须进行以下更改以使用支持片段而不是常规片段 -

在 main.xml 中，更改

class="com.google.android.gms.maps.MapFragment"/>

到

class="com.google.android.gms.maps.SupportMapFragment"/>

在你的activity.java中，改变

public class LocationProfileManagerActivity extends Activity {

到

public class LocationProfileManagerActivity extends FragmentActivity {

Maps API v2 无法在模拟器中运行，因为它依赖于捆绑在 Google Play 商店 .apk 中的 Google Play 服务。不过，它可以一起被破解，你可以在这里阅读关于“谷歌地图 v2 模拟器”的第一个谷歌结果。此外，您仍然可以在有限的时间内使用 V1，您可以从这里开始。

你需要做两个改变

由于您的 sdk 版本低于 12，因此需要进行以下更改

1) main.xml

代替

  class="com.google.android.gms.maps.MapFragment"/>

和

class="com.google.android.gms.maps.SupportMapFragment"/>

2)活动.java

需要扩展FragmentActivity而不是Activity

如果您想在模拟器中进行测试，请下载google_play_services_apk并将其安装在模拟器中。
