Show a DialogFragment in Xamarin.Android

Question

I have a class which is derived from Android.App.DialogFragment , now I need to show this dialog fragment. I am trying to show this dialog fragment from a class which is derived from Android.Support.V4.App.Fragment . The following code is what I use to show the DialogFragment :

 Android.Support.V4.App.FragmentTransaction ft = FragmentManager.BeginTransaction();
            PlaylistSettingsDialogFragment psdf = new PlaylistSettingsDialogFragment();
            psdf.Show(ft, "PlaylistSettings");

I get a error from the last line. It says:

Cannot convert the first parameter(ft) from Android.Support.V4.App.FragmentTransaction to Android.App.FragmentManager

Answer 1

Show method for DialogFragment has 2 variants:

int     Show(FragmentTransaction transaction, String tag)

or

void    Show(FragmentManager manager, String tag) 

so You can use it like this:

Android.Support.V4.App.FragmentTransaction ft = FragmentManager.BeginTransaction();
PlaylistSettingsDialogFragment psdf = new PlaylistSettingsDialogFragment();
var transactionId = psdf.Show(ft, "PlaylistSettings");

or

PlaylistSettingsDialogFragment psdf = new PlaylistSettingsDialogFragment();
psdf.Show(FragmentManager, "PlaylistSettings");

I usually use these lines of code to use Dialog Fragment in xamarin android i hope it helps!

FragmentTransaction fragmentTransaction = _activity.FragmentManager.BeginTransaction();
                    //remove fragment from backstack if any exists
                    Fragment fragmentPrev = _activity.FragmentManager.FindFragmentByTag(_activity.Resources.GetString(Resource.String.dialogfragment_tag_name));
                    if (fragmentPrev != null)
                        fragmentTransaction.Remove(fragmentPrev);
                    fragmentTransaction.AddToBackStack(null);
                    DialogFragmentFeedBackRating dialogFragment = DialogFragmentFeedBackRating.NewInstace(null,_activity);
                    dialogFragment.Show(fragmentTransaction, _activity.Resources.GetString(Resource.String.dialogfragment_tag_name));
