I recently wanted the title of my activity to scroll like a marquee whenever it was too long to fit in its space (because it is fetched from the net and can be pretty much anything). I didn't want to use a custom multi-line title view because that would waste screen space and because I want to preserve the native look and feel. The solution I've found is rather hackish, but it works. Here goes the code, with explanatory comments and all:
// make the title scroll!
// find the title TextView
TextView title = (TextView) findViewById(android.R.id.title);
// set the ellipsize mode to MARQUEE and make it scroll only once
title.setEllipsize(TruncateAt.MARQUEE);
title.setMarqueeRepeatLimit(1);
// in order to start strolling, it has to be focusable and focused
title.setFocusable(true);
title.setFocusableInTouchMode(true);
title.requestFocus();
Hi. I tried the code but does not work. Even I set max lines to 1. Are you sure TextView is focusable?
ReplyDeleteYew Felix I too didnt find this working..
ReplyDeleteThanks, worked straight away as-is. The only edit I needed was to change to setMarqueeRepeatLimit(-1) for continuous scrolling.
ReplyDeleteThanks, worked out of the box.
ReplyDeleteI'm not sure why you think that's "hackish". That's simply a feature of the system. :D
ReplyDeleteIt doesn't work for me either...
ReplyDeleteMake sure of
ReplyDelete1)title.setMarqueeRepeatLimit(-1); in java file
2)android:singleLine="true" attribute in TextView of layout.xml file.
3) in manifest file.
Works like a charm...Thanks Felix :)
Hi All,
ReplyDeleteThanks a lot for the code, it works like a charm. Anyway I'm currently using the native ActionBar provided by the Theme.Holo theme of android, and I had a hard time finding the title item. So I'll share some code required to ensure you are using the title TextView of the ActionBar.
From the main activity of your application you can do this: http://pastebin.com/jVtEi3GD
I hope someone finds this usefull.
Regards.
Wow man you did it, i was fooling around looking for the $·"%$ id, thank you.
