问题
The horizontal progressbar in ActionbarSherlock is too thin, and is very hard to see. How can I style it to be a few pixels thicker?
I've tried applying a custom style in styles.xml by inhering the style from Widget.Sherlock.Light.ProgressBar.Horizontal, but it's really confusing and I don't know which properties to set.
回答1:
Instead of attempting to make the ProgressBar thicker, try using a color that contrasts from the ActionBar color to make it stand out, and be noticible.
That's what I did with my app. I have a grey ActionBar, with a bright red ProgressBar.
Hope this helps!
