Tablayout + viewpager in Fragment, müssen ein EditText Daten in viewpager löschen

Question

ich ein Projekt mit Tablayout mit 3 viewpager Artikel entwickelt haben, Daten in edittext von jedem viewpager bekommen, ich brauche von viewpager alle Daten zu löschen und alle uns gesetzt leer, wenn ein Button-Klick-Ereignis eintritt, das zuletzt eingestellt wurde viewpager item.

Dies ist übergeordnete fragment, Homefragment .class-

     Log.i("MYLOG", "Message was not handled " + e.getMessage()); 

    } 
    Toast.makeText(getActivity(), "Cleared ", Toast.LENGTH_SHORT).show(); 
} 
} 

Ich habe versucht, die Einzelteile durch diese Methode zu löschen,

1. edittext.setText(" ");
2. edittext.getText().clear();

Nur Ordnung und Klasse Zahlung allein Daten Daten erhalten gelöscht Kunde konnte nicht gelöscht. Wie behebe ich mein Problem?

Answer 1

versuchen, diese mViewPager.setOffscreenPageLimit(3); innen setUpViewPager() Methode

Upate

standardmäßig eingestellt setOffscreenPageLimit() auf 1 gesetzt wird, das heißt youll 2 ​​-Fragment Seiten haben auf einmal aktiv. Da Sie die Texte von EditText aller drei Fragmentseiten löschen müssen, wird die Einstellung setOffscreenPageLimit(3) (weil Sie 3 Fragmente verwenden) alle 3 Fragmentseite aktiv und hilfreich bei der Durchführung notwendiger Änderungen in allen haben. Für weitere Informationen siehe das Docs

Leere setOffscreenPageLimit (int limit) Legen Sie die Anzahl der Seiten, die auf beiden Seiten der aktuellen Seite in der Ansichtshierarchie in einem Ruhezustand gehalten werden sollen. Seiten über diese Grenze hinaus werden bei Bedarf vom Adapter neu erstellt.
