How to make Google Play like TextView animation when text is too long?

In Google Play when the name of a certain title is too long then they apply an animation on this TextView when the name is going out from one end of the TextView, goes in from the other end, stops for a second on the beginning of the Title text, and then goes for the next round.
Does anyone have any explanation how can this be achieved?

This was what worked for me, you have to actually request for focus in order for the marquee animation to work:
<TextView
android:id="#+id/tvAddress"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="#+id/tvName"
android:layout_toLeftOf="#+id/ivLogo"
android:text=""
android:textColor="#color/cups_white"
android:textSize="18sp"
android:ellipsize="marquee"
android:singleLine="true"
android:marqueeRepeatLimit ="marquee_forever"
android:scrollHorizontally="true"
android:focusable="true"
android:focusableInTouchMode="true"
android:duplicateParentState="true">
<requestFocus
android:focusable="true"
android:focusableInTouchMode="true"
android:duplicateParentState="true" />
</TextView>

In your xml file where the TextView is declared you can use the following attributes:
android:ellipsize="marquee"
android:marqueeRepeatLimit="marquee_forever"
android:singleLine="true"
with the singleline you going sure thats the Text is showend only in one line.

Android: TextView is not scrolling Automatically

I have a TextView with following attributes :
<TextView
android:id="#+id/appheader"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_centerVertical="true"
android:textColor="#ffffff"
android:layout_marginLeft="3dp"
android:textSize="21sp"
android:singleLine="true"
android:ellipsize="marquee"
android:marqueeRepeatLimit="marquee_forever"
android:scrollHorizontally="true"
android:focusable="true"
android:focusableInTouchMode="true"/>
Actually the TextView scrolls ONLY when I click the TextView. But I want to scroll it automatically when I launch the Activity. How can I do this ?

<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="very long text to srollll dkfjadkfjkldjfkjdkghjhtudhfjhdjfkdfkadjsajekdfjak"
android:singleLine="true"
android:marqueeRepeatLimit="marquee_forever"
android:ellipsize="marquee"
android:focusable="true"
android:focusableInTouchMode="true"/>

By-default TextView marquee effect works when it get focus. To make an automatic marquee effect you need to extend TextView class. See this link for reference.

set android:scrollHorizontally="true" for that textview.
Also set the following two properties:
text.setMovementMethod(new ScrollingMovementMethod());
text.setSelected(true);
