http://forum.xda-developers.com – Hello. I wanted to edit the text of the pop-up lists to another color. As the above image suggests, the text color cannot be seen. So, I wanted to know how to change the pop-up list's text color to white or any other color. I do not know the location of the particular xml file which contains the text color of the list. I searched a lot, and almost all the users that did ask this ques never got an answer.. So, if anyone knows the location, do share it.:) Thank You. PS: I want to write down this location in a diary, open it up and check it after 3 decades!:fingers-crossed: (HowTos)
