Android:MapView使用GoogleMap

在建立專案時，BuildSDK要選GoogleAPIs版本的

<Manifest>
開啟網路權限以及地圖之程式庫
<uses-permission android:name="android.permission.INTERNET"/>
<uses-library android:name="com.google.android.maps"/>


<XML>

 <com.google.android.maps.MapView
                android:id="@+id/map"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:apiKey="0lDmUngY4dnrsMtVjU12ySKKSMU-y2G0edVeXXX"
                <--讓地圖可以滑動-->
                android:clickable="true" >


            </com.google.android.maps.MapView>
