Calling DialogFragment from Fragment (not FragmentActivity)?

Question

I do have a FragmentActivity which contains a Fragment list (with methods to navigate between them). In one of those fragments I need to call a DialogFragment to display a "zoom" on a Picture contained in that fragment.

But it seems that you can't call a DialogFragment directly from a Fragment.

Is there any way to get some kind of "callback" to the FragmentActivity to make this display the DialogFragment over the fragment.

Or simply a "glitch" to call it directly from the Fragment.

If that is the case what are my options?

Answer 1

When you create a new Dialog, you can simply call it using this (very) simple method from a Fragment.

DialogFragment dialog = DialogFragment.instantiate(getActivity(), "Hello world"); dialog.show(getFragmentManager(), "dialog"); 

If you want to use your own dialog, please use that kind of code.

public class MyDialogFragment extends DialogFragment {     //private View pic;      public MyDialogFragment()     {     }      @Override     public Dialog onCreateDialog(Bundle savedInstanceState)     {         View view = getActivity().getLayoutInflater().inflate(R.layout.fragment_my_dialog, new LinearLayout(getActivity()), false);          // Retrieve layout elements         TextView title = (TextView) view.findViewById(R.id.text_title);          // Set values         title.setText("Not perfect yet");          // Build dialog         Dialog builder = new Dialog(getActivity());         builder.requestWindowFeature(Window.FEATURE_NO_TITLE);         builder.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));         builder.setContentView(view);         return builder;     } } 

Answer 2

it will help if you need to show a fragment dialog inside a fragment

DialogFragment

public class DialogBoxFragment extends DialogFragment {     @Override     public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){         View rootView = inflater.inflate(R.layout.dialog_fragment, container, false);         getDialog().setTitle("simple dialog");         return rootView;     } } 

Now showing the fragment dialog into a fragment

DialogFragment dialogFragment = new DialogFragment ();                             dialogFragment.show(getActivity().getFragmentManager(),"simple dialog");
