Answer 1

entfernen
if (convertView==null) { } else { } beiden Gruppen und Kind. Es wird in Ihrem Szenario funktionieren.

Answer 2

können Sie gemeinsame Vorliebe verwenden Sie den Wert Ihrer EditText zu speichern und zu füllen, wann immer und notwendig ...

Answer 3

Try-Tag zu jeder Ansicht einzustellen.

für zB

holder.compliance.setTag(Integer.parseInt(groupPosition+""childPosition)); 

oder Sie können eine beliebige eindeutige Nummer in setTag geben den Tag zu erkennen, in diesem Fall habe ich die Kombination von Gruppenposition und Kind verwendet.

dann abrufen Tag

holder.compliance.getTag();
