I've spent most of the day searching and trying various solutions and while I've come most of the way, I'm cursed by the "close" (maybe it has more appropriate name, idk) button on the nav bar when the keyboard is displayed (as in the attached image.)
I have a few editTexts which allow the user to adjust some parameters before a graph is recomputed and redrawn. I need to know when their input is complete. I've managed to sort out the "Done" button but for the life of me I can't figure out how to handle hitting that close button. I've also adapted some code which determines if the keyboard was opened and then closed (which is the case with these editTexts) but it only works when using the Done button (so is somewhat redundant).
So.. is there some way of picking up when the user has closed the keyboard using the nav bar?
