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

I've read all the other questions relating to this issue, but none of them have actually solved the problem.

The problem is on different android versions the title text color is changing automatically so it looks sometimes ugly. I want to set a standard title text color for all smartphones.

问题 I show a DialogFragment from another DialogFragment . I need to set title and a button just next to it. I don't want to reimplement the theme and create a custom view inside DialogFragment 's content view instead of dialog title (because it's error-prone and time wasting). Is it even possible?

问题 So I previously solved this problem thanks to the help of another thread, but due to some new changes to my app the previous solution no longer works. Here's the previous thread: Android App: Replace default button background with custom background in a Dialog Fragment I'm trying to style the background drawables of the positive/negative buttons of a custom DialogFragment, and cannot seem to get any change to stick.
