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

Question

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?

Answer 1

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>

Answer 2

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.
