TabActivity 구성 방법(xml 레이아웃 파일 이용)

1. xml 파일의 구성

<?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:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        android:padding="5dp" >

        <TabWidget
            android:id="@android:id/tabs"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />

        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:padding="5dp" />
    </LinearLayout>

</TabHost>

XML파일 작성시 요구사항

• 탭호스트: android:id="@android:id/tabhost"
• 탭   위젯: @android:io="@android:id/tabs"
• 탭컨텐트: @android:id="@android:id/tabcontent"

 

2. java파일 작성

package com.android.example.hellotabwidget;

import android.app.TabActivity;
import android.content.Intent;
import android.content.res.Resources;
import android.os.Bundle;
import android.widget.TabHost;

public class HelloTabWidget extends TabActivity {

 public void onCreate(Bundle savedInstanceState) {   
        TabHost.TabSpec spec; 
        Intent intent; 
     
       super.onCreate(savedInstanceState);
       
       //반드시 getContentView()가 getTabHost()보다 먼저 호출되어야 함
        setContentView(R.layout.main);   
        Resources res = getResources();
        TabHost  tabHost = getTabHost();
        // TabHost  tabHost = (TabHost) findViewById(android.R.id.tabhost);
        // tabHost.setup();
    
        // Artist 탭
        intent = new Intent().setClass(this, ArtistsActivity.class);   
        spec = tabHost.newTabSpec("artists").setIndicator("Artists",                     
                            res.getDrawable(R.drawable.ic_tab_artists)).setContent(intent);    
        tabHost.addTab(spec);   

         // Album 탭
        intent = new Intent().setClass(this, AlbumsActivity.class);             
        spec = tabHost.newTabSpec("albums").setIndicator("Albums",                     
                         res.getDrawable(R.drawable.ic_tab_albums)).setContent(intent);   
        tabHost.addTab(spec);  

        // Song 탭
        intent = new Intent().setClass(this, SongsActivity.class);   
        spec = tabHost.newTabSpec("songs").setIndicator("Songs",                     
                          res.getDrawable(R.drawable.ic_tab_songs)).setContent(intent);   
        tabHost.addTab(spec);
        
        // 앱이 실행될때 초기에 선택되어질 탭
        tabHost.setCurrentTab(2);
    }
}
