      android:tag="@+id/mvMain" 
      android:enabled="true" 
      android:clickable="true" /> 

</LinearLayout>

我沒有得到這兩個語句（forcebly關閉應用程序）地圖=（MapView的地圖）findViewById（R.id.mvMain）; map.setBuiltInZoomControls（true）;
如果它必須工作我需要給我什麼？

使用它： - main.xml--

<?xml version="1.0" encoding="utf-8"?> 
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
     android:orientation="vertical" android:layout_width="fill_parent" 
     android:layout_height="fill_parent"> 
    <RelativeLayout 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:enabled="true" 
       android:clickable="true" android:apiKey="0zWsBUUrp7PHyoVnmV5qN5nHhXhZ-VJHhlnjYig" /> 
      <LinearLayout android:id="@+id/zoom" 
       android:layout_width="wrap_content" android:layout_height="wrap_content" 
       android:layout_alignParentBottom="true" 
       android:layout_centerHorizontal="true" /> 
     </RelativeLayout> 
</LinearLayout>

在activity--

LinearLayout zoomLayout = (LinearLayout)findViewById(R.id.zoom); 
    View zoomView = mapView.getZoomControls(); 

    zoomLayout.addView(zoomView, 
     new LinearLayout.LayoutParams(
      LayoutParams.WRAP_CONTENT, 
      LayoutParams.WRAP_CONTENT)); 
    mapView.displayZoomControls(true);

使用它

Hpoe它會幫你..
