Android：无法从视图投射到图库

我想在android 中制作一个图库。为了设置需要获取我在 xml 文件中定义的图库的适配器。我这样做是：图库 g = (图库) findViewById(R.id.gallery1); 但是使用这段代码我无法编译我的项目，因为我收到错误“无法从视图转换到图库”。我的 xml 文件如下所示： “

<?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"
   >
 <Gallery android:id="@+id/gallery1"
       android:layout_width="fill_parent"
       android:layout_height="wrap_content"
       android:gravity="bottom"
 />
</LinearLayout>

有人知道如何解决我的问题吗？非常感谢

I'd like to make a Gallery in android. In order to set the adapter in need to get the gallery which I defined in my xml file. Im doing that as:
Gallery g = (Gallery) findViewById(R.id.gallery1);
But with this code I can't compile my project, since I get the Error "Cannot cast from View to Gallery". My xml-file looks like this:
"

<?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"
   >
 <Gallery android:id="@+id/gallery1"
       android:layout_width="fill_parent"
       android:layout_height="wrap_content"
       android:gravity="bottom"
 />
</LinearLayout>

Anybody knows how to solve my problem? Thanks a lot
