Mein CardView in einem RecyclerView gestaffelt sah in dieses Format ähnlichCardView plötzlich in RecyclerView
jetzt ist es heraus gesperrt
Es ist ein kleines passiert k vor. Ich dachte, ich hätte eine Codezeile verlegt. habe keine Ahnung was ich gemacht habe. Ich dachte, es wäre ein kleiner Fehler, den ich irgendwann finden würde ....
Ein Moment, der Adapter war in Ordnung, dann im nächsten Moment, es ist alles auseinander. Ich habe mir die lokale Geschichte angeschaut usw. Ich kann nicht finden, was ich getan habe.
Wenn es nichts Kleines ist, habe den Verdacht, dass irgendwie die RecyclerView-Bibliothek in meinem Projekt irgendwie durcheinander ist, weil ein anderer Adapter, den ich in einem anderen Bereich benutzte, auch das Abstandsproblem hat. Allerdings bin ich nirgendwo in der Nähe gewesen.
Allerdings habe ich einen anderen RecyclerView-Adapter aus einem anderen Projekt online kopiert und eingefügt, und es lief gut in meinem, so glaube ich, dass ich einen Fehler gemacht habe irgendwo, den ich nicht finden kann. UPDATE 3/22 Ich habe es geschafft, ein Backup zu finden, das ich gemacht habe, bevor das alles aufkam. Ich kopierte den "schlechten" Code und fügte ihn in das unbeschädigte Backup ein und der Adapter kam so heraus, als ob er es sein sollte. Im Original erscheint es jedoch nicht so.
