  • @Nishit Panchal did you got the solution?I am not sure but i think for seekbar you can use circular image view and set its background to desired color that u want and for filter i think you have to filter your layout color. – Danish Nov 08 '21 at 18:34
  • @Danish thanks for your reply...i think i need to add more information about the question so here i am giving a brief desc: so basically i want to create a night mode app which willl run in the background and change the colour of the whole screen to green or any desired colour. i want to create a app similar like this app : https://play.google.com/store/apps/details?id=com.eyefilter.nightmode.bluelightfilter – Nishit Panchal Nov 10 '21 at 15:20
