问题 I'm trying to work out the correct way to pass in an Object to a Fragment or DialogFragment without breaking the 'empty constructor' rule. For example I have created a custom View and for each one I instantiate I want to associate a DiaglogFragment. This DialogFragment will be used to display controls with which the user can alter certain aspects of the custom View it is associated with. Because View is an Object I understand I cannot use setArguments(). I could implement a newInstance(View)

问题 I am working on my first Android application. I just came to discover Fragments and I need them to create a ViewPager to create nice transitions between my activities, but I fear that it's too late to implement that.

问题 Strange, neither Fragment nor v4.Fragment implemented the "onContextMenuClosed". Other events are there, like onCreateContextMenu and onContextItemSelected. I need to clean up something when the context menu is dismissed, which can be activated by back button, tapping on the blank area on screen, or select one menu item in the context menu. How do I monitor the dismissal of a context menu in a fragment then? 回答1: The menu close event in a fragment will also trigger its parent activity's
