Android定制TabHost

我无法在自定义tabHost中传递intent。请任何人帮助我。我尝试将intent从customtabactivity.java传递到firsttab.java，其中包含作为setcontentview的firsttab.xml

Main.xml }

firsttab.xml

}

您好，这将使用full创建tabhost。如果您想在单个选项卡中切换活动，也可以创建ActivityGroup

public class MyTabHost extends TabActivity 
{   
public static TabHost tabHost;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    Resources res = getResources(); // Resource object to get Drawables
    tabHost = getTabHost();  // The activity TabHost 
    TabHost.TabSpec spec;  // Resusable TabSpec for each tab
    Intent intent;  // Reusable Intent for each tab



    intent = new Intent().setClass(this, MyFirst1.class);
    spec = tabHost.newTabSpec("MyFirst1").setIndicator("",res.getDrawable(R.drawable.image1)).setContent(intent);
    tabHost.addTab(spec);


    intent = new Intent().setClass(this, MyFirst2.class);
    spec = tabHost.newTabSpec("MyFirst2").setIndicator("",res.getDrawable(R.drawable.image2)).setContent(intent);
    tabHost.addTab(spec);


    tabHost.setCurrentTab(0);
}

}

我想在程序中传递intent。在何处调用intent。我尝试调用，但无法。因为我已经创建了spec，所以请查看将传递intent的代码。
