I called it Helixbar. It could've been a Snailbar, but I like Helixbar :) Hope you like it.

This is my implementation effect
how to use ?
in layout.xml
<com.cjj.SnailBar
android:id="@+id/seekBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:thumb="@anim/snailanim" />SnailBar is a subclass of Seekbar, so you can use it like Seekbar
seekBar = (SeekBar) findViewById(R.id.seekBar);about me
