我使用的只有一个选项卡主机单Tab_bar.class

I am using only one single Tab_bar.class for Tab Host

public class Tab_Bar extends TabActivity  {

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.tab);
    setTabs() ;

}
 void setTabs()
{
    addTab("My Profile", R.drawable.home_normal, MyProfile.class);
    addTab("Search", R.drawable.search_normal, JobSearch.class);

    addTab("Saved Jobs", R.drawable.starred, Saved_jobs.class);
    addTab("Job Alert", R.drawable.job_match, JobAlert.class);
}

private void addTab(String labelId, int drawableId, Class<?> c)
{
    TabHost tabHost = getTabHost();
    Intent intent = new Intent(this, c);
    TabHost.TabSpec spec = tabHost.newTabSpec("tab" + labelId); 

    View tabIndicator = LayoutInflater.from(this).inflate(R.layout.tab_indicator, getTabWidget(), false);
    TextView title = (TextView) tabIndicator.findViewById(R.id.title);
    title.setText(labelId);
    ImageView icon = (ImageView) tabIndicator.findViewById(R.id.icon);
    icon.setImageResource(drawableId);

    spec.setIndicator(tabIndicator);
    spec.setContent(intent);
    tabHost.addTab(spec);
    tabHost.setCurrentTab(1);

}

我使用这些XML文件 TabIndicator.xml

I am using these xml file TabIndicator.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="0dip"
android:layout_height="55dip"    
android:layout_weight="1"
android:orientation="vertical"

 android:background="@drawable/tab_indicator"
android:padding="5dp">

<ImageView android:id="@+id/icon"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:src="@drawable/icon"

/> 

 <TextView android:id="@+id/title"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true" 
    android:layout_centerHorizontal="true"
    style="?android:attr/tabWidgetStyle"
    android:textSize="13sp"

/>    

和Tab.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">

    <FrameLayout android:id="@android:id/tabcontent"
        android:layout_width="fill_parent" android:layout_height="0dip"
        android:layout_weight="1" />

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

推荐答案

这是不是eaxctly你所需要的，但可能的帮助。我用这个设置来创建动态选项卡，然后做不同的事情与他们。

This is not eaxctly what you need, but might help. I used this setup to create dynamic tabs and then do different things with them.

protected void onCreate(Bundle savedInstanceState) {
...

    final TabHost Tabs = (TabHost) findViewById(android.R.id.tabhost);
    Tabs.setup();
    int count;
        for (count =0;count < 2;count++){

            ...

            final int passedTabId = count; 
            NewTab.setContent(new TabHost.TabContentFactory()
            {
                public View createTabContent(String tag)
                {

                   ...

                 RelativeLayout layout = new RelativeLayout(getApplicationContext);
                android.widget.RelativeLayout.LayoutParams params = 
                    new RelativeLayout.LayoutParams(
                LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
                layout.setLayoutParams(params);
                layout.setId(some ID);
                layout.setBackgroundResource(R.drawable.room_background);

                   TextView dynText = new TextView(getApplicationContext);
                    ...
                   layout.addView(dynText);


                   return layout;

    // You can set onClickListeners, etc here and then assign them some functions you need
 // You can also create different layouts for every tab according to the passedTabId
                }

            });

            Tabs.addTab(NewTab);
        }
}

事情是，你不能只是简单的设置其它活动在每个选项卡中运行。您需要设置您需要您在该选项卡中创建对象的某些功能，但主要的活动是相同的。祝你好运：）

Thing is, you cant just simply set another activity to run in each tab. You need to set some functions you need to the objects you create in that tab, but the main activity remains the same. Good luck :)
