iPhone- like tab bar in Android?

<?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:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"        
android:layout_marginBottom="0dp" 
>
    <FrameLayout
    android:id="@android:id/tabcontent"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"            
    android:layout_weight="1" 
    />

    <TabWidget
    android:id="@android:id/tabs"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_weight="0"
   />
</LinearLayout>
</TabHost>

There's a tutorial for creating a "Tab Layout" on the android dev site:

You can implement your tab content in one of two ways: use the tabs to swap Views within the same Activity, or use the tabs to change between entirely separate activities

_{(source: android.com)}

There are a couple of examples around

This one is scrollable http://code.google.com/p/mobyfactory-uiwidgets-android/

Sorry, I really don't know the iPhone, but may a QuickAction Dialog help you??

I imagine a list of some activities in that dialog.

I hope this is close to what you want.
