The four attributes that you mention can be applied to a ProgressBar
‘s style like so:
style="?android:attr/progressBarStyleHorizontal"
The style constant android:progressBarStyleHorizontal
is your typical incremental progress bar:
While the other three are varying sizes of the same circular progress bar:
style="?android:attr/progressBarStyleSmall"
style="?android:attr/progressBarStyle"
style="?android:attr/progressBarStyleLarge"
Update:
According to adamp’s comments:
These are attributes of the theme that
point at themed styles you can use for
progress indicators…They are not attributes for ProgressBar itself.
