Пример динамического создания табов:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TabHost android:id="@+id/tabhost"

<FrameLayout android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingTop="62px">
<Button android:id="@+id/buttontab"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:text="A semi-random button"
/>
</FrameLayout>
</TabHost>
</LinearLayout>

Java:

public class DynamicTabDemo extends Activity {

Button btn=(Button)tabs.getCurrentView().findViewById(R.id.buttontab);
btn.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
TabHost.TabSpec spec=tabs.newTabSpec("tag1");
spec.setContent(new TabHost.TabContentFactory() {
