use this programmatically not from xml:
textView.setSingleLine(true);
textView.setEllipsize(TruncateAt.MARQUEE);
textView.setFocusableInTouchMode(true);
textView.setFreezesText(true);
textView.setMarqueeRepeatLimit(-1);
textView.setFocusable(true);
textView.setSelected(true);
With xml you use this :
<TextView
android:id="@+id/tVMessage"
style="@style/tVMessage"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:textDirection="anyRtl"
android:singleLine="true"
android:text="Good bye Good bye Good bye Good bye Good bye Good bye Good bye Good bye Good bye Good bye Good bye Good bye Good bye Good bye Good bye Good bye Good bye Good bye Good bye Good bye Good bye Good bye" />
use single line in your xml.
