Android: TextView is not scrolling Automatically

Question

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 ?

"scroll it automatically" are you referring to marquee here? — waqaslam, Apr 23 '12 at 07:29
Could you define "scroll" more? Because if you want it to scroll through the text that is in the TextView, you're gonna have a problem, since you've put it on singleLine="true". — Loyalar, Apr 23 '12 at 07:30
Why the text won't scroll if we set singleLine="true". Its working for me. — Dileep Perla, Apr 23 '12 at 09:42

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);
