Android TabHost 구성 요소 사용 방법 상세 설명

최근 에 Contacts 소스 코드 를 연 구 했 는데 위 에 자신 이 쓴 TabHostTest 프로그램 을 본 떠 서 다음 과 같이 정리 합 니 다.
main.xml 레이아웃 파일:

<?xml version="1.0" encoding="utf-8"?> 
<TabHost xmlns:android="http://schemas.android.com/apk/res/android" 
 android:id="@android:id/tabhost" 
 android:layout_width="match_parent" 
 android:layout_height="match_parent"> 
 
 <LinearLayout 
  android:orientation="vertical" 
  android:layout_width="match_parent" 
  android:layout_height="match_parent"> 
 
  <TabWidget android:id="@android:id/tabs"

   android:layout_width="match_parent" 
   android:layout_height="0dip" 
   android:layout_weight="1" 
  /> 
 </LinearLayout> 
</TabHost> 

inner.xml 파일:

<?xml version="1.0" encoding="utf-8"?>

  <TabWidget android:id="@android:id/tabs"
