fix(android): Fix keyboard hiding "done" button
Major changes: - Add Done FAB to AppBottomBar when editing (shows checkmark button) - Lift editing state from FileViewScreen to MainActivity via callback - FileViewScreen notifies parent of editing state changes - Wrap entire UI in Box with imePadding() so bottom bar moves with keyboard - Add adjustResize to manifest for keyboard handling - Remove nested Scaffold from FileViewScreen (use parent's bottom bar) - Add inline formatting support (bold, italic, code, strikethrough, links) - Fix content corruption when switching between editable blocks Architecture: - AppBottomBar accepts isEditing and onDoneClick parameters - FileViewScreen exposes onEditingChanged callback with save function - MainActivity tracks editing state and passes save callback to bottom bar - Enter key now inserts newlines; use Done button to finish editing Prompts: - "the 'done' button gets hidden by the keyboard because it's bottom right, how do other apps have these floating buttons without ending up covering the thing being worked on or being covered up by the keyboard" - "top-right: yuck. smaller - not really a fix. inline, maybe. or what a toolbar at the bottom stuck to the top of the keyboard. we are likely to add more stuff like bold, italic etc" - "@shutter_20264-13_08.png - missed!" - "still way off. is it because it's on top of the home bar in the app?" - "so what is our current bar with the home button and hamburger? that should move with the keyboard too and probably include the done button" - "toolbar looks tidy and works, but still hidden by keyboard (doesn't move up at all)" - "Two things, 1, this has way too much padding above the keyboard, and 2 this can cover up the textbox the user is editing. ideas?" - "fab when the edited block is near top, if I pick a block near the bottom it scrolls the content up (which is good, though not quite far enough), but the bottombar goes way over" - "that's worse i've reverted that. it is supposed to move up with the keyboard, but not fly off the top of it" - "nope" (with screenshot showing gap still present) - "that's the wrong answer, the tick should still be there, keyboard or no, and you haven't fixed it. i'm convinced you are using the wrong pattern here entirely. think about the proper kotlin/android UI design pattern for things that stick to the bottom keyboard or not. research if needed" - (provided link to Android BottomAppBar docs) - "aaaaaaaaaand now we are back to it being stuck at the bottom, do you know what you are doing? do you need to think harder?" - "no change, keyboard still covers it. will @run-apk-adb-emulator.sh definitely get the updated manifest?" - "omg you are so bad at following your instructions. read the current commit message, and add in all the prompts you couldn't be arsed to add" - "include what I just said, stop leaving gaps" Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> https://developer.android.com/develop/ui/compose/components/app-bars#bottom This patch moves the Done button into the existing bottom nav bar (with the hamburger & home button), and makes the bar move up to stay visible when the keyboard slides up.
