Seek bar, change path color from yellow to white

Question

Hello,

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 , it turns the line traversed from grey to yellow. I want track/line to either remain grey or white..Basically I want just the thumb to move with no color change in the seek bar.

2) How to change the thumb of seekbar from rectangle to circle/sphere/round shape.

any pointers will be appreciated.

You should set SeekBar XML properties:

<SeekBar 
            ....
    android:progressDrawable="@drawable/progress"
    android:thumb="@drawable/thumb"
            ....
/>

Where progress is something like this:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android"&gt;
<item android:id="@android:id/background" 
    android:drawable="@drawable/background_fill" />

<item android:id="@android:id/progress">
    <clip android:drawable="@drawable/progress_fill" />
</item>

and thumb is

<?xml version="1.0" encoding="utf-8"?>    
   <selector xmlns:android="http://schemas.android.com/apk/res/android"&gt;
   <item android:drawable="@drawable/thumb_fill" />
</selector>
