Android - 繪製路徑

使用此示例Drawing a line/path on Google Maps我不斷收到來自LogCat的以下錯誤信息：它顯示無法找到類com.google.android.maps.Mapview - 我已導入com.google.android。 maps.MapView但不知道如何創建這個明顯的類 - 可有人請指教？謝謝Android - 繪製路徑

您是否在清單中包含下一行？

<uses-library android:required="true" android:name="com.google.android.maps" />

，並把它在正確的地方（開放應用標籤後），例如：

<application 
    android:hardwareAccelerated="true" 
    android:icon="@drawable/ic_launcher" 
    android:label="@string/app_name" > 
    <uses-library 
     android:name="com.google.android.maps" 
     android:required="true" /> 

    <activity ...

我有同樣的問題，我發現我失蹤了「谷歌」參考在我的XML標籤。我最初有它像「com.android.maps.MapView」這是顯而易見的錯誤。它應該像下面的東西

<com.google.android.maps.MapView 
    android:id="@+id/map" 
    android:apiKey="mapAPIkey" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:clickable="true" 
/>
