Ich habe versucht, mehrere RecyclerView innerhalb eines Layouts zu implementieren, das Teil einer zusammenklappenden Registerkarte ist. Allerdings funktioniert meine RecyclerView nicht und ich weiß nicht, was ich in meinem Code falsch gemacht habe. Bitte hilf mir! HierRecyclerView wird nicht ordnungsgemäß angezeigt (scrunched up)
ist die Github-Link: github.com/arxbombus/RecipeDetails
Hier ist die gewünschte Ansicht: image
Hier ist, was ich aus irgendeinem Grund immer: image
Wie Sie kann sehen, alles ist alles zusammengeknüllt. :(
Unten habe ich die Layouts für meine MainActivity und auch die Java-Dateien für meine Adapter enthalten.
Hier ist meine activity_main.xml

}habe ich alle meine Code hier nicht, weil ich denke, die Frage ist lang genug, aber ich würde wirklich schätzen, wenn jemand mir geholfen. Vielen Dank!
kann u ... mehr darüber –
jede Ausnahme erklären? –
@NileshRathod Ich versuche ein RecyclerView zu erstellen, aber aus irgendeinem Grund wird es nicht richtig angezeigt und ich weiß nicht warum. Ich habe mehrere Elemente hinzugefügt, aber es zeigt sich nur als eines der Elemente und alles ist zusammengeknüllt. – Harrison
