Suche ListView mit onClick zeigt falsche Ergebnisse

Question

Meine Listview funktioniert ordnungsgemäß, aber ich suche mit einem SearchView nach einem Element in der Listview suchen. Wenn ich anfänglich auf ein Element in der ursprünglichen Listenansicht klicke, wird ein Dialogfeld angezeigt, das sich auf das angeklickte Objekt bezieht, aber nach der Suche ist der angezeigte Dialog falsch. Genauer gesagt zeigt es den Dialog des ursprünglichen Listview-Elements an dieser Position. Bitte helfen

Answer 1

Sie falsch machen hier

titlePosition = allTitles.get(position); 
expense = expenseManager.getExpense(titlePosition); 

Da es Daten von der ursprünglichen Liste von dieser Position geben wird. Sie müssen die getItem-Methode der Adapterklasse verwenden. in diesem Verfahren übergeben Position, wie es Daten gefiltert hat. für weitere Informationen here

aktualisieren

titlePosition = (String) adapter.getItem(position); 
expense = expenseManager.getExpense(titlePosition); 

überprüfen diesen Code versuchen.
