Ich habe auf Click-Ereignis meiner Listview in meinem managerActivity hookied aber es funktioniert nicht. Ich habe auch meinen kundenspezifischen Adapter angeschlossen. Ich habe einen Test-Toast im Onclick-Ereignis angezeigt, aber es funktioniert nicht. Bitte helfen

Answer 1

Fügen Sie die Zeile (android: descendantFocusability = "blocksDescendants") in Sie Adapter xml Eltern Layout und android einfügen: fokussierbarem = "false" in der Checkbox oder Button in der Adapter xml-Datei.

Answer 2

Überprüfen Sie die ausgewählte Antwort here - die eine Möglichkeit bietet, was Sie tun möchten. Aber auch wenn Sie this answer betrachten, müssen Sie bestätigen, dass Sie keine fokussierbaren Objekte in Ihrem Zeilenlayout setzen - weil dies verhindert, dass die ListView die Berührungsereignisse erhält.
