Ich habe Listenansicht mit mehreren Elementen. Jede Zeile enthält Bild und Text im Zick-Zack-Verfahren Ich überprüfe die Position if ((Position% 2) == 0) Dann füge ich Bild an links und Text an rechts und sonst ich Bild rechts und Text nach links. es funktioniert ordnungsgemäß, aber wenn ich scrollen oder scrollen, dann bekomme ich ein Problem mit der Sequenz. Ich brauche wie diese 
Android Listview Sequenz falsch
Listview, aber wenn ich zur Listenansicht scrollen dann i wie dieses

Ihr Code extrem versaut besteht. Das gepostete Problem hängt mit der Wiederverwendbarkeit der Zeilenansicht zusammen. Ich denke, Sie sollten versuchen, Recycle View zu verwenden. Übrigens, warum setzen Sie die Ränder dynamisch? Sie können linkes und rechtes Layout in .xml erstellen und Ränder von Dimen –
