Seek bar, change path color from yellow to white

Question

I have two questions:

1) how do I change the color of the seek bar (path) from yellow (the default color) to white. What I mean to say is, while I slide the thumb ,

Answer 1

I want to complete the answer from above for the people who are new to the system,

the missing xmls ( background_fill , progress_fill and progress could look like that for a gradient red

progress.xml

background_fill.xml

progress_fill.xml

i did not complete the implementing for android:thumb, so the thumb will be still the original one

Therefore we just have to delete this line again from our layout xml where we define the seekbar

android:thumb="@drawable/thumb"

Good luck!!!
