다른 탭 안에있는 버튼

Question

3 개의 탭이 있고 각각 하나가 Activity를 확장하고 View.OnClickListener를 구현합니다. SomeTabActivity로 구현 된 OnClickListener가 일부 탭을 선택하고 버튼을 클릭하면 작동하지 않습니다. 왜? 내 활동을 만들려면 어떻게해야합니까? 일부 탭을 선택할 때마다 새로운 활동을 시작해야합니까?

내 코드 :

// 주요 활동

public class TripoidActivity extends TabActivity { 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 
     init(); 
    } 

    private void init() { 
     final TabHost tabHost = (TabHost) findViewById(android.R.id.tabhost); 
     tabHost.setup(); 
     final Resources res = getResources(); 

     createTabA(tabHost, res); 
     createTabB(tabHost, res); 
     createTabC(tabHost, res); 

    } 

} 

// 탭 A 활동

public class TabAActivity extends Activity implements View.OnClickListener { 


    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     init(); 
    } 

    private void init() { 
     buttonAddItem = (Button) findViewById(R.id.btAddItem); 
     buttonAddItem.setOnClickListener(TabAActivity.this); 
    } 

    @Override 
    public void onClick(View v) { 
     //do something (show a toast msg) 
    } 

    } 

// 메인 레이아웃 XML

<?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="fill_parent" 
    android:layout_height="fill_parent" > 

    <LinearLayout 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent" 
     android:orientation="vertical" 
     android:padding="5dp" > 

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

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

      <include layout="@layout/tab_a" /> 
      <include layout="@layout/tab_b" /> 
      <include layout="@layout/tab_c" /> 

     </FrameLayout> 
    </LinearLayout> 
    </TabHost>
