.xml（アンドロイド）のCoverviewウィジェット

Question

Coverviewはhttp://www.inter-fuser.com/2010/02/android-coverflow-widget-v2.htmlから実装されたウィジェットのアイブで、ボタンや素材を追加する代わりに.xmlを使用するまで動作します。

（これは、IVEが運とリンクが、しようとするものです）

マイmain.xml：私は2つをリンクする方法が分からないし、すべてのヘルプは本当に

私の主な活動をいただければ幸いですあなたは

のsetContentようなものが必要ビューとリンクする

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




<cover.flow.test.CoverFlow 
    android:id="@+id/coverflow" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:layout_above="@+id/button1" 
    android:layout_alignParentTop="true" /> 


<Button 
    android:id="@+id/button1" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_alignParentBottom="true" 
    android:layout_centerHorizontal="true" 
    android:text="Button" /> 

Answer 1

ビュー（R.layout.main）;

と（その代わりなど、findViewByIdでそれを得る）
