如何制作类似于Gmail或G +的“进度栏”？

Question

I could add a simple progressbar to XML activity and put a padding / margin negative, but I think Google inserted directly into the actionbar progressbar.

If I do something like this:

Activity act = this;
act.setProgress (20 * 100);
...

In the action bar displays a spinner, but I'm interested in one horizontal style bar as does Google. What is the best solution?

I am using android-support-v7 to be compatible with older versions (I'm not interested in using libraries like ActionBarSherlock)

Answer 1

There is no built-in component in Android that does what you want. I suggest you use the third party ActionBar-PullToRefresh instead.
