我是android的新手,面对map的问题。在我的应用程序中,我可以看到包含地图的框但是地图除了白色网格外什么也没有显示,我看到一些以前的stackoverflow回答了同样的问题,但仍然不能解决问题。请帮助我。谢谢。

我的清单文件包含

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.maps"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="19" />
    <uses-permission android:name="android.permission.INTERNET">
    </uses-permission>

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <uses-library android:name="com.google.android.maps"/>
        <activity
            android:name=".Main"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <meta-data
        android:name="com.google.android.maps.v2.AIzaSyDhp2d1pq1R7qg0p4BjqdTCwaRuuXckTJU"
        android:value="AIzaSyDhp2d1pq1R7qg0p4BjqdTCwaRuuXckTJU"/>
        </application>
</manifest>

我的布局活动文件包含:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" 
    >
    <com.google.android.maps.MapView
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:apiKey="AIzaSyDhp2d1pq1R7qg0p4BjqdTCwaRuuXckTJU"
          android:id="@+id/mapdata"
          />
</LinearLayout>

我从unix命令获得了这个键

sau@sau-HP-Pavilion-dv6-Notebook-PC:/usr/local/java/jdk1.8.0_20/bin$ ./keytool 
-list -alias androiddebugkey -keystore /home/sau/.android/debug.keystore 
-storepass android -keypass android androiddebugkey, 11 Oct, 2014, PrivateKeyEntry, 

Certificate fingerprint (SHA1): 32:6D:54:16:96:66:82:39:EC:4C:5B:3A:16:79:
B3:96:EF:77:9D:C2

我使用这个sha1来获取密钥AIzaSyDhp2d1pq1R7qg0p4BjqdTCwaRuuXckTJU,

    Key for Android apps (with certificates)
    API key:    
    AIzaSyDhp2d1pq1R7qg0p4BjqdTCwaRuuXckTJU
    Android apps:   
    32:6D:54:16:96:66:82:39:EC:4C:5B:3A:16:79:B3:96:EF:77:9D:C2;com.example.maps

你的宣言应该是:

<?xml version="1.0" encoding="utf-8"?>

    <permission
        android:name="com.errorpoint.findlocation.permission.MAPS_RECEIVE"
        android:protectionLevel="signature" />

    <uses-permission android:name="com.errorpoint.findlocation.permission.MAPS_RECEIVE" />

    <uses-sdk

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity

            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <meta-data

            android:name="com.google.android.maps.v2.API_KEY"
            android:value="Key goes here" />
    </application>

</manifest>

xml文件

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <fragment
        android:id="@+id/map"
        android:name="com.google.android.gms.maps.MapFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</LinearLayout>
