android - How to animate the textview (very very long text )scroll automatically horizontally

Question

I am not interested in Marquee because, in Marquee you can not control the speed of marquee. I have tried to animate the textview but Parent view clips the text at the end even though all parent layout and view groups encompassing textviews are set with two flags clipchildren= false, clipToPadding=false.

Am I missing something or is there a better work around ?

The xml looks like

<TextView
        android:id="@+id/textview1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true"
        android:layout_marginBottom="66dp"
        android:maxLines="1"
        android:singleLine="true"
        android:textColor="#585858"
        android:textSize="32sp" >
    </TextView>

and code snippet look like

TextView textView2 = (TextView)findViewById( R.id.textview1 );    
textView2.startAnimation((Animation)AnimationUtils.loadAnimation(this, R.anim.translate));

I think you can use translate animation. Something like this

<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="5000"
    android:fromXDelta="100"
    android:interpolator="@android:anim/linear_interpolator"
    android:repeatCount="infinite"
    android:repeatMode="restart"
    android:toXDelta="-100" />

And add to your textview like this

textview.startAnimation((Animation)AnimationUtils.loadAnimation(Context,R.anim.scroll_animation));

Hope it can help you.
