Ich habe eine Autocompletetextview zum Öffnen von URLs in Webview verwendet. Ich möchte ".com" als Postfix automatisch zu URLs hinzufügen, die keine Erweiterungen wie .com, .tv, .co.in, etc. haben. Problem ist aber, wie man überprüft, ob in der eingegebenen URL bereits eine Erweiterung vorhanden ist . Ich suchte danach und fand dieses post, aber es prüfte nur für bestimmte bekannte Erweiterungen. Ich möchte prüfen, ob eine Erweiterung vorhanden ist oder nicht. Wenn die Erweiterung vorhanden ist, öffnet sie die URL, wenn nicht, fügt ".com" als Postfix zu URL hinzu.Postfix zu URL in Autocompletetextview hinzufügen
