Fire event when marquee completes

问题:

I want to marquee text, and when the marquee completes (the 1 full marquee cycle), I want to trigger another event. Is there a good way to do this? I haven't seen an OnEnd or similar function when marquee-ing a textview

回答1:

using a custom TextView, you can override onDraw to use reflection on mMarquee field and on mStatus field of the mMarquee field (see TextView code on grepcode or such).

mStatus value is 2 when marquee is running, and 0 when stopped.

onDraw is called a lot, but in particular, it is called right after the marquee is completed.
