[Android] Tab 이미지 배경색 넣기, 아이콘 생성하기.

일반적으로 Tab의 배경 이미지 적용은 간단하다.
즉, 아래와 같이 "setBackgroundColor()" 를 적용하면 간단하다.

'm_tabHost.getTabWidget().getChildAt(0).setBackgroundColor(Color.parseColor("#534512"));'
하지만, 내가 원하는 것은 아래와 같이 여러 속성을 적용하고자 한다.

- 'Touch 했을 때 색상 or 이미지'
- 'Touch Up 했을 때 색상 or 이미지'
- 'Tab에 포커싱 되어 있을 때 색상 or 이미지'
...

위와 같이 하기 위해서는 기본으로 제공되는 Android Control을 조합해야 한다.

※ Example Code
- TapView_Custom.java
public class TapView_Custom extends TabActivity implements OnTabChangeListener {
    /** Called when the activity is first created. */

    private TabHost m_tabHost = null;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        
        setContentView(R.layout.tapview_custom_layout);
        
        /** TabHost ID */ 
        m_tabHost= (TabHost)findViewById(android.R.id.tabhost);  
        TabSpec aaa_TabSpec = m_tabHost.newTabSpec("aaa");  
        TabSpec bbb_TabSpec = m_tabHost.newTabSpec("bbb");
        TabSpec ccc_TabSpec = m_tabHost.newTabSpec("ccc");
        
        LayoutInflater vi1 = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        LayoutInflater vi2 = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        LayoutInflater vi3 = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View View_1 = (View)vi1.inflate(R.layout.tab_row_item, null);        View View_2 = (View)vi2.inflate(R.layout.tab_row_item, null);
        View View_3 = (View)vi3.inflate(R.layout.tab_row_item, null);
        LinearLayout Layout_1 = (LinearLayout)View_1.findViewById(R.id.LinearLayout01);
        LinearLayout Layout_2 = (LinearLayout)View_2.findViewById(R.id.LinearLayout01);
        LinearLayout Layout_3 = (LinearLayout)View_3.findViewById(R.id.LinearLayout01);
        Layout_1.setBackgroundResource(R.drawable.tab_1_bg);
        Layout_2.setBackgroundResource(R.drawable.tab_2_bg);
        Layout_3.setBackgroundResource(R.drawable.tab_3_bg);
        
        ImageView iv_1 = (ImageView)View_1.findViewById(R.id.icon);
        ImageView iv_2 = (ImageView)View_2.findViewById(R.id.icon);
        ImageView iv_3 = (ImageView)View_3.findViewById(R.id.icon);
        
        TextView tv_1 = (TextView)View_1.findViewById(R.id.text);
        TextView tv_2 = (TextView)View_2.findViewById(R.id.text);
        TextView tv_3 = (TextView)View_3.findViewById(R.id.text);
        tv_1.setText("aaa");
        tv_2.setText("bbb");
        tv_3.setText("ccc");
        
        aaa_TabSpec.setIndicator(View_1);
        aaa_TabSpec.setContent(new Intent(this,test_activity.class));  
        bbb_TabSpec.setIndicator(View_2);
        bbb_TabSpec.setContent(new Intent(this,test_activity.class));  
        ccc_TabSpec.setIndicator(View_3);
        ccc_TabSpec.setContent(new Intent(this,test_activity.class));  
        
       /** 탭을 TabHost 에 추가한다 */ 
        m_tabHost.addTab(aaa_TabSpec);        m_tabHost.addTab(bbb_TabSpec);
        m_tabHost.addTab(ccc_TabSpec);
        
        m_tabHost.getTabWidget().setCurrentTab(0);  
    }
}
