Suche Ansicht ist nicht meine Gridview Suche

Question

Alles in dem Code unten funktioniert außer die, wenn Sie versuchen und nach einem Wert suchen, reagiert die Anwendung nur nicht, wenn Sie Buchstaben in die Searchview eingeben, die die Gridview filtern sollte.

String[] Champions = {"Aatrox", "Ahri", "Akali"};

Answer 1

Sie haben einen kleinen Fehler in dieser Zeile:

if (filterlist.get(i).getChampion().toUpperCase().contains(constraint)); 

der Fehler ist ; Symbol am Ende der if Aussage. Es macht Code unter if laufen jedes Mal, daher funktioniert Filter nicht. Entfernen Sie einfach ; Symbol nach if Anweisung
