Scrollview scrollt nicht im Fragment

Question

AKTUALISIERTE FRAGE: Ich versuche zu scrollen, aber nicht zu blättern. Überprüfen Sie das Bild:

OLD:
Ich habe 5 mehr cardviews in meinem Linearlayout, aber ich klebte nur 1. Ich weiß nicht, was Probleme mit der Scroll verursacht. Ich habe bereits versucht, das erste lineare Layout zu entfernen, aber nicht funktioniert.
