SeekBar with min, max and negative values ​​for android

I am trying to create a SeekBar on Android and I would like to set its maximum and its minimum using both negative and positive values; for example, I would like to select a minimum of 5 and a maximum of 150; I can do this, and it's pretty simple: you can subtract minValue from the progress value and that's ok ...

My problem is that I am trying to set negative high and low.

Can anyone help me?

thank
