Ticker TextView in Notification Layout

Is there a way to make a TextView in a custom Notification layout look like a ticker? I'm using the following code to set Notification layout.

mNotificaionView = new RemoteViews(getPackageName(), R.layout.status_bar);
mNotificaionView.setTextViewText(R.id.ticker, getLongText());
mNotification.contentView = mNotificaionView;

And the following attrs for TextView in status_bar.xml

android:singleLine="true" 
android:ellipsize="marquee"
android:marqueeRepeatLimit ="marquee_forever"
android:scrollHorizontally="true"
android:focusable="true"
android:focusableInTouchMode="true"

In fewer words, how do I create a ticker like TextView in a RemoteViews object?

Look at Any.DO SmallWidget(4x1).

It's a ticker that fades text in and out. And it's an AppWidget. How does it work?

  • Create an array of colors for the text, from the opaque, to the transparent and then to the opaque again.
  • Create an alarm that when triggered it changes the text's color to the current color in the above array (the current index in the array will be saved).
  • Make the alarm create a another one, to do the same for the next index in the array
  • When the index is in the transparent part of the array - change the text to the next line we want to present
  • When reaching the last index, we'll reset the array's index, and set an alarm to start the whole thing again. That alarm will be set to about 5 seconds from that moment (to give the user enough time to read the text)

The problem - battery consumption. All those alarms don't do well with the battery, but test it to see how bad is it first.

I never tried this on a notification bar widget, but since they are built with the same technique, this might work.

Good luck!

This should work, but only while your View has focus. See this answer, it may help you. Android notification Marquee not working
