How to increase the rotation speed in android?

Question

I have an image drawable. i rotating the image like a progress bar.

Answer 1

According to this link:

The rotation speed of the indeterminate progress bar is fixed at one revolution every 4 seconds, changing the duration attribute in the drawable XML has no effect. If you prefer to speed it up, you can change the toDegrees attribute to multiples of 360:

• 720 makes one turn in 2 seconds
• 1080 makes one turn in 1.33 seconds
• 1440 makes one turn in 1 second

In addition, you can just use indeterminateDuration for the ProgressBar.
