You can simply set progressDrawble,thumb and backgroung attribute and you will get all you want.
// ------------ custom seekbar
LayerDrawable layer = (LayerDrawable) verticalSeekBar_1
.getProgressDrawable();
Drawable draw1 = (Drawable) layer
.findDrawableByLayerId(android.R.id.progress);
Bitmap bitmap1 = BitmapFactory.decodeResource(getApplicationContext()
.getResources(), R.drawable.scroll_on);
draw1 = new ClipDrawable(new BitmapDrawable(bitmap1),
Gravity.AXIS_PULL_BEFORE, ClipDrawable.HORIZONTAL);
layer.setDrawableByLayerId(android.R.id.progress, draw1);
Drawable draw2 = (Drawable) layer
.findDrawableByLayerId(android.R.id.background);
Bitmap bitmap2 = BitmapFactory.decodeResource(getApplicationContext()
.getResources(), R.drawable.scroll_off);
draw2 = new BitmapDrawable(bitmap2);
layer.setDrawableByLayerId(android.R.id.background, draw2);
