Android custom circular ProgressBar direction

I guess you're using an rtl language? You can force the progress bar to an ltr or clockwise direction by setting the layoutDirection property on your ProgressBar.

<ProgressBar
    ...
    android:layoutDirection="ltr" />

By using latest versions of material design library, you can achieve this:

  • in the layout with this attribute
    app:indicatorDirectionCircular
    
  • or programmatically with this method
    setIndicatorDirection()
