확장 가능 목록 뷰, 수직 하위

Question

http://www.techienjoy.com/android-expandable-list-dynamically-created-example.php과 같은 확장 가능한 목록을 만들었지 만, 아이가 가로로 보이지 않게 세로로 보게하고 싶습니다. 다른

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:orientation="vertical" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent"> 
<ExpandableListView android:id="@android:id/list" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:groupIndicator="@null"/> 

모든 클래스에 있습니다

난 단지 1 XML을 가지고있다. 어떻게 수직으로 설정할 수 있습니까? 내 자바 코드는 링크와 동일합니다.
