So senden Sie einen Wert von einem Fragment an ein anderes Fragment von Recyclerview Adapter. Dann schließe das erste Fragment und öffne das neue Fragment.

Question

Ich muss einen Wert senden, wenn ich auf eine Zeile in recyclerview auf ein anderes Fragment klicke (Ich verdünne OnBind im Adapter). Dann muss ich das Fragment, das die Recycleransicht enthält, schließen und das Empfängerfragment öffnen. Ich habe irgendwo gelesen, dass wir Bundle verwenden können, aber ich bin ziemlich neu in der Android-Programmierung, also bin ich verwirrt.

Dies ist das Fragment, das RecyclerView

Answer 1

Sie enthalten Datenbündel-Fragment unter Verwendung senden. EG. `Bündel Daten = neues Bündel(); data.putString ("Schlüssel", "Wert");

NewFragment newFragment = new NewFragment(); newFragment.setArguments (eventDetailsData); `

Dann laden Fragment.

Um das aktuelle Fragment zu löschen/entfernen, führen Sie den folgenden Code aus: getActivity(). OnBackPressed();
