I got it the marquee TextView working after all !
A bit of a mystery about the combination of attributes that works so
maybe I am relying on undocumented behavior.
For some reason adding android:focusableInTouchMode="true" causes the
marquee to activate. Why is that?
android:focusable="true" is required for the marquee to work. But it
won't start scrolling until you navigate with the down arrow key to
the marquee view. With focusableInTouchMode it also starts scrolling
initially (which is what I wanted).
Not sure why that view initially has focus. There are two buttons in
a RelativeLayout above this view. Why does this text marquee start
scrolling and get focus initially?
Here is what works:
<TextView
android:id="@+id/WantaMarqueeText"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:paddingLeft="4dp"
android:paddingRight="4dp"
android:singleLine="true"
android:ellipsize="marquee"
android:focusable="true"
android:focusableInTouchMode="true"
android:text="Blah blah blah on and on we go
andlongwordandmore"
></TextView>
Adding the <requestFocus> element child to the TextView or any other
view doesn't seem to do anything.
