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

Since SeekBar uses colorAccent by default, you can create a new style with your custom color as colorAccent then use theme attribute to apply it to the SeekBar.

<SeekBar>
    .
    .
    android:theme="@style/MySeekBarTheme"
    .
</SeekBar>

in the @style:

 <style name="MySeekBarTheme" parent="Widget.AppCompat.SeekBar" >
        <item name="colorAccent">#ffff00</item>
 </style>
