當我滾動可展開的listview時，我已經在bean中保存了edittext值所有的值都被刪除。如何保存價值和地位？
任何人都可以建議如何保存edittext值？EditText在滾動Expandable ListView時丟失值

將標記設置爲textview，然後再次在滾動上檢索標記。 –
你可以請簡單解釋一下。我把setTag和getTag來獲得價值嗎？ – Babu
'final ChildViewHolder finalHolder = holder;'和'final ChildViewHolder finalHolder = holder;'。你應該擺脫那些無用的東西。他們將始終指向最後調用getGroupView的項目。 – greenapps
