Create volume control for android app - repost

I am designing a music player application, I am doing it myself but I want to complete this in 24 hours so I need someone's help. I want a developer to design one "Volume Control" horizontal slider. You don't need to write the whole code, I just want the slider to move Left/Right horizontally. I'll take care of rest of the thing. You can find the type of control I am looking for in the following application [login to view URL] Or you can have a look at picture attached.
