android-dialogfragment

I am trying to call a DialogFragment from my Fragment class. I have an ImageView, and would like to call my DialogFragment class in the onClickListener of the ImageView I have set up. I am getting an error in the onClick with the code I have set up trying to call the DialogFragment. I am getting an error on "show" stating "The method show(FragmentManager, String) in the type DialogFragment is not applicable for the arguments (FragmentManager, String)" and an error on "new Instance" stating "The method newInstance() is undefined for the type MyDialogFragment" Here's my code: @Override public

I need to handle the end of a DialogFragment (after a call to .dismiss) - for example, I would show a toast inside the activity that "contains" the fragment after dismiss. How do I handle the event?

It may be worthwhile noting that I am running this on API 24 so issues with transitions not being supported below version 21 is not the problem.

I am currently messing around with DialogFragment to learn to use it. I assumed that compared to onCreateView() , onCreate() can do this: public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); testTextView.setText("SUCCESS!"); //ERROR HERE } But I am wrong. Not sure why its not working. The error goes away when I comment out testTextView.setText("Success!"); The error is a NullPointerException, and then it just flags line 39 which is where the offending line of code is. Any clarifications much appreciated. EDIT: public View onCreateView(LayoutInflater inflater,
