CodePudding user response：

I don't know how to do that with progressBar, but you can create a Layout in the shape of progressBar with four views separated with vertical guidelines, and color each view with different color. Then programatically change the percents of the guidelines and the visibility of the view on buttons click.

Use material design Progress indicator and change indicator color dynamically when pressing on the specific button.

add dependency in your gradle,

implementation "com.google.android.material:material:1.5.0"
