Android地图活动标题未显示

androidgoogle-maps
4

我将跟随Hello MapView的示例，但我的地图标题无法显示，不知道是什么原因导致了这个问题。

以下是我的主清单文件：

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

        </intent-filter>
    </activity>
    <uses-library android:name="com.google.android.maps" />
</application> </manifest>

我的地图布局

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/mainlayout"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <com.google.android.maps.MapView
        android:id="@+id/mapview"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:clickable="true"
       android:apiKey="0f724slL07SJV93E_oZAPQDt54ewoD-PD7zTmDw"
    />

我的电脑有两个硬盘，我的代码存储在一个硬盘上，而Java JDK和Eclipse存储在另一个硬盘上，这可能导致问题吗？

你能上传你的Logcat记录吗？ - Shabbir Panjesha
真的不明白你的问题是什么。请粘贴您的代码和 Logcat 详细信息。 - Arun Badole

我已经检查了您的日志记录。几天前我也遇到了同样的问题。我发现当您的apiKey与keystore不兼容时，会出现异常“java.io.IOException: Server returned: 3”。请检查apiKey是否与keystore兼容。这是您需要解决的唯一问题。 - Shabbir Panjesha

ApiKey 在调试版本和发布版本中是不同的。也许您已经将发布密钥库的指纹提供给了该网站？ 如果是这样，您也需要为调试密钥库执行相同的操作。
是的，你说得对。我忘记了调试版和发布版的apikey是不同的。 - dns

我认为这是您的API密钥的问题... Google Maps API

我的manifest.xml文件...您看到有什么不同吗？

<com.google.android.maps.MapView
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 android:apiKey="XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX" />
