Question

My application needs to create a small ProgressBar programmatically.
ProgressBar doesn’t have a method to set the style (I want a small
ProgressBar). The constructor can take an AttributeSet, however, it is an
interface and requires me to implement a set of functions. Is there a way
to set the ProgressBar to a small style? (I can’t use XML to create
ProgressBar.)

Most of the time if you provide an AttributeSet manually you have to use one of Android’s. Luckily, they’ve exposed the attribute set that describes a small progress bar. Use this code:

progressBar = new ProgressBar(activity, null, android.R.attr.progressBarStyleSmall);
