Android SeekBar custom material style, you could refer to :

Create your custom SeekBar style :

<style name="MySeekBar" parent="Widget.AppCompat.SeekBar">
    <item name="android:progressBackgroundTint">#f4511e</item>
    <item name="android:progressTint">#388e3c</item>
    <item name="android:colorControlActivated">#c51162</item>
</style>

Use it in your axml :

<SeekBar
    android:id="@+id/mySeekBar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    style="@style/MySeekBar"
