Androidビューポケットベルとリサイクルビュー

Question

リサイズビューを使用してリストを表示したいのは、ビューページャ内です。 （例：アンドロイドのホームページのアイコンのように） しかし、ここではリストは表示されず、表示されずにページャーで表示されます。

誰が

activity.xml

<android.support.v4.view.ViewPager 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/pager" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" /> 

obj_tile.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:orientation="vertical" 
    android:padding="5dp"> 

    <ImageView 
     android:id="@+id/iv_icon" 
     android:layout_width="50dp" 
     android:layout_height="50dp" 
     android:src="@android:drawable/alert_light_frame" /> 

    <TextView 
     android:id="@+id/tv_title" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:maxLines="2" 
     android:text="Group Title" /> 

</LinearLayout>
