问题 I have an android app that uses some custom dialogs which are inflated from XML layouts. The contents of the dialog's view come from the XML layout, but the actual positive and negative buttons are added by calling the builder's setPositiveButton and setNegativeButton methods, so I have no control over (or at least don't know how to control) the styling of the buttons themselves.

问题 I have a DialogFragment that I launch when a user taps a menu item on the ActionBar. Everything about the Dialog functions properly - it launches just fine and it does everything I've set it up to do. Unfortunately, as soon as I rotate my device, the DialogFragment disappears. This seemed to be a common problem back in 2012 - I've scoured StackOverflow and tried all of the common fixes that have been posted in the last couple of years.

问题 Scenario : I am having a list fragment which displays a list of friends. When an list item is pressed, I'm showing the details of the friend in a dialog fragment. Problem: In the dialog fragment, I'm having an option to delete the friend from my friend list (in a remote server) . I'm using Async tack to perform this. After returning from the dialog fragment, how should I update the 'old' friend list. How do I trigger a fragment 'reload'. Since the async task is not aware of the custom list

问题 I don't understand DialogFragment at all. How to create one, how to get the user input out of it, and set it into a TextView. I would like for the TITLE button, when clicked, to bring up a DialogFragment asking the user to enter the title of their Mood Board. The user enters a title. When they click the PostiveButton "Done", the user's title is set into the top left frame of the mood board, which has a TextView with a hint. Please! Ask questions, because I don't really understand the dialog

问题 When I set the style of a dialog fragment, the android is allowing to take the screen shot of dialog fragment, but after removing the style it works. Below is the code of dialog fragment's onCreate @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setStyle(DialogFragment.STYLE_NO_TITLE, android.R.style.Theme_Holo_Light); getActivity().getWindow().setFlags(WindowManager.LayoutParams.FLAG_SECURE, WindowManager.LayoutParams.FLAG_SECURE);
