How to hide/show thumb in a SeekBar

Question

I'm trying to hide the thumb of seekBar by default and show it if you touch the seekbar for the first time, but I can't make the thumb invisible. I tried:

• https://stackoverflow.com/a/20855816/5479029 but then I can see a white gap instead of the thumb
• https://stackoverflow.com/a/43145751/5479029 but then the thumb is placed in a wrong place when I try to make it visible again and use this mySeekBar.setThumbOffset(0);
• seekbar.getThumb.setVisible(false, false) - it doesn't work as well

How can I do that?

Answer 1

Try this way:(To remove gap)

seekbar.setSplitTrack(false);
seekbar.getThumb().mutate().setAlpha(0);

Or, You can add following In the seekbar's XML layout.

android:splitTrack="false"
