在我的布局 xml 中：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <TextView
        android:id="@+id/tv_distance_time"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" 
        android:layout_alignParentTop="true" />

    <fragment 
        android:id="@+id/map"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"        
        class="com.google.android.gms.maps.SupportMapFragment" 
        android:layout_below="@id/tv_distance_time" />    

</RelativeLayout>

在 MainActivity 中：

 SupportMapFragment fm =
 (SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map);

我的 manifest.xml ：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    </application>

</manifest>

更新：

我在 manifest.xml 中添加了以下代码：

<meta-data
    android:name="com.google.android.gms.version"
    android:value="@integer/google_play_services_version" /> 

我将片段元素从：

<fragment 
    android:id="@+id/map"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"        
    class="com.google.android.gms.maps.SupportMapFragment" 
    android:layout_below="@id/tv_distance_time" />

到：

 <fragment
    android:name="com.google.android.gms.maps.SupportMapFragment"
    xmlns:map="http://schemas.android.com/apk/res-auto"
    android:id="@+id/map"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@id/tv_distance_time"/> 

我的项目运行了，但是我在屏幕上看不到任何地图。（我在真实设备上测试过）。

Answer 1

您需要将布局文件中的片段更改为：

<fragment 
    android:id="@+id/map"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"        
    class="com.google.android.gms.maps.SupportMapFragment" 
    android:layout_below="@id/tv_distance_time" />   

收件人：

 <fragment
    android:name="com.google.android.gms.maps.SupportMapFragment"
    xmlns:map="http://schemas.android.com/apk/res-auto"
    android:id="@+id/map"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

仔细看看：class="com.google.android.gms.maps.SupportMapFragment"之间的区别

和：

android:name="com.google.android.gms.maps.SupportMapFragment"

还请阅读我就该主题撰写的这篇博文，确保您没有遗漏任何您在 Manifest xml 文件中遗漏的 mata-data 部分，从您收到的错误中可以清楚地看出这一点：

Google Maps API V2 Guide

更新：

您在清单文件中有双重权限：

<!-- Required OpenGL ES 2.0. for Maps V2 -->
<uses-feature
    android:glEsVersion="0x00020000"
    android:required="true" />

<!-- Requires OpenGL ES version 2 -->
<uses-feature
    android:glEsVersion="0x00020000"
    android:required="true" />

您应该删除其中一个。 而且您没有理由使用SupportMapFragment，因为您正在为高于11 的API 编写应用程序。所以只需使用MapFragment，并对Activity 进行相关更改。

Answer 2

您的清单中缺少此元标记：

<meta-data
    android:name="com.google.android.gms.version"
    android:value="@integer/google_play_services_version" />

错误中很明显地说明了：

> java.lang.IllegalStateException: The meta-data tag in your app's
> AndroidManifest.xml does not have the right value.  Expected 5089000
> but found 0.  You must have the following declaration within the
> <application> element:     <meta-data
> android:name="com.google.android.gms.version"
> android:value="@integer/google_play_services_version" /> 09-03

Answer 3

只需在AndroidManifest.xml 文件中的<application> 标记内添加以下行

<meta-data
 android:name="com.google.android.gms.version"
 android:value="@integer/google_play_services_version" />

如果您想获取 GoogleMap，则可以按如下方式对其进行初始化以访问它并将其加载到您的应用程序中。

更改以下代码行：

SupportMapFragment fm =
 (SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map);

到

private GoogleMap mMap;
mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
                .getMap();
