Show DialogFragment from onActivityResult

Question

I have the following code in my onActivityResult for a fragment of mine:

onActivityResult(int requestCode, int resultCode, Intent data){
   //other code
   P         


        

Answer 1

EDIT: Yet another option, and possibly the best yet (or, at least what the support library expects...)

If you're using DialogFragments with the Android support library, you should be using a subclass of FragmentActivity. Try the following:

onActivityResult(int requestCode, int resultCode, Intent data) {

   super.onActivityResult(requestCode, resultCode, intent);
   //other code

   ProgressFragment progFragment = new ProgressFragment();  
   progFragment.show(getActivity().getSupportFragmentManager(), PROG_DIALOG_TAG);

   // other code
}

I took a look at the source for FragmentActivity, and it looks like it's calling an internal fragment manager in order to resume fragments without losing state.

I found a solution that's not listed here. I create a Handler, and start the dialog fragment in the Handler. So, editing your code a bit:

onActivityResult(int requestCode, int resultCode, Intent data) {

   //other code

   final FragmentManager manager = getActivity().getSupportFragmentManager();
   Handler handler = new Handler();
   handler.post(new Runnable() {
       public void run() {
           ProgressFragment progFragment = new ProgressFragment();  
           progFragment.show(manager, PROG_DIALOG_TAG);
       }
   }); 

  // other code
}

This seems cleaner and less hacky to me.
