Animate/hide button when close to end of ListView

由 谁都会走 提交于 2019-12-11 22:08:27
问题 I have view like this: ListView is on the whole screen and the button is always visible (on FrameLayout). I want to hide the button outside the screen (below it) with animation when user is scrolling list and he's reaching the end (animation must start before he reaches the end so it could nicely move out of the screen). How to achieve that? EDIT Thanks to PPartisan I created simple method onScroll which is working very well: public void onScroll(AbsListView view, int firstVisibleItem, int

I want that button to be always visible. With this code, the RelativeLayout and the button are not displayed. Where am i wrong? RelativeLayout (fixed) - Button

Android: Make view on top of listview scroll together with the listview

由 泪湿孤枕 提交于 2019-12-03 13:19:30
问题 I have a listview which is obviously scrollable. The listview contains some form questions.
