How to handle a decibel meter type component/widget?

Question

I'd like to be able to have some sort of volume panel looking something like :

|||||||||||||||||||||

Where the lines highlight according to how loud/quiet the sound is according to decibels. Is there a built in Android component to handle this, or does anyone have any ideas as to how I could handle this?

Answer 1

My approach would be to use a Rating Bar and override the android:numStars value to be the number of bars you want. Then, create a drawable that will replace the star images with bars. Really hope this helps.

Best of luck.
