阅读更多关于 DialogFragment buttons pushed off screen API 24 and above

问题 I am making a custom DialogFragment that displays a selectable list of data. The list is too long to fit on the screen without scrolling. For up to API 23, everything seems to work fine, but when I test on API 24+, the DialogFragment's button's are no longer visible. I looked at Missing buttons on AlertDialog | Android 7.0 (Nexus 5x), but that doesn't seem to apply because my buttons do show up when I reduce the amount of content in the list so that it all fits on the screen. How can I make

阅读更多关于 Detect back button but don't dismiss dialogfragment
