到达子活动中标题栏中的按钮

Question

创建带有按钮的标题栏时，这在所有活动中都很常见，例如在选项卡活动中创建的标题栏。如何才能到达所有子活动中的按钮？

public class tabActivity extends TabActivity  implements OnClickListener{
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState);
    c = this;
    requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);

    setContentView(R.layout.tabactivity);

    getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.window_title);

    mTabHost.addTab(mTabHost.newTabSpec("tab_test1").setIndicator("Settings",
            res.getDrawable(R.drawable.preferences)).setContent(
                    new Intent(this, Settings.class)));

    mTabHost.addTab(mTabHost.newTabSpec("tab_test1").setIndicator("About",
            res.getDrawable(R.drawable.newspaper)).setContent(
                    new Intent(this, About.class)));

这是我初始化选项卡和带有按钮的自定义标题的地方。

在这个类中，我想访问自定义标题中的按钮。：

public class About extends Activity 
{
@Override
public void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);

    setContentView(R.layout.about);

    ImageView imag = (ImageView) findViewById(R.id.Position);
    imag.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {
            // TODO Auto-generated method stub
            System.out.println("heeey");
        }
    });

}

侦听器不起作用？

呼这可能吗？

public class tabActivity extends TabActivity{ 
public void onCreate(Bundle savedInstanceState) {  
    super.onCreate(savedInstanceState); 
    c = this; 
    requestWindowFeature(Window.FEATURE_CUSTOM_TITLE); 

    setContentView(R.layout.tabactivity); 

    ImageView imag = (ImageView) findViewById(R.id.Position);         
    imag.setOnClickListener(new OnClickListener() {         

    public void onClick(View v) {         
       tabActivity.listener.onClick(v);
    }         

    getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.window_title); 

    mTabHost.addTab(mTabHost.newTabSpec("tab_test1").setIndicator("Settings", 
        res.getDrawable(R.drawable.preferences)).setContent( 
                new Intent(this, Settings.class))); 

    mTabHost.addTab(mTabHost.newTabSpec("tab_test1").setIndicator("About", 
        res.getDrawable(R.drawable.newspaper)).setContent( 
                new Intent(this, About.class))); 
}

public static void setListner(OnClickListener listener)
{
    tabActivity.listner = listener;
}

主活动没有实现 eventListener

public class About extends Activity implements OnClickListener
{      
    @Override      
    public void onCreate(Bundle savedInstanceState)       
    {      
        super.onCreate(savedInstanceState);      

        setContentView(R.layout.about);      

    });         

    public void onResume()
    {
        tabActivity.setListener(this);
    }


}      

代码是这样的。很难解释

这样做的目的是什么？事件控件在主活动中可用。
