Doppelklicken Sie auf OnClickListener eines Recycler View Adapters
Ich versuche, einem Element einer Recycling-Ansicht eine einfache Klick-Ansicht hinzuzufügen. Aus irgendeinem Grund muss ich jedoch zweimal auf ein Element klicken, um eine Aktion auszuführen. Auf einen Klick scheint es so, als würde der Recycler View keinen Klick erkennen. Beim nächsten erkennt es jedoch das Klicken und führt eine geeignete Aktion aus.

Ich konnte anscheinend das Problem nicht finden, das dieses Problem verursacht. Kann ich dazu bitte Hilfe bekommen? Vielen Dank
