我需要幫助。我得到「getText()。toString()」的錯誤,它說:「getTEXT方法應該從UI線程調用......」這是什麼意思呢?當提交數據時,數據不會保存在數據庫中。有人可以幫我請我的時間不多了已經?:'(如果有需要什麼,讓我知道getText()。toString()常量和資源類型不匹配
這裏是我的代碼:。

請更新您的代碼屬性,你不能比UI線程其他UI組件訪問由
args[]
提到他們。你也聲明瞭相同的字符串變量2次,所以更新你的代碼。讓我知道你更新後得到什麼錯誤 – Alok嗨,幫助我確定哪個變量,我宣佈2次?我只是從我研究複製粘貼。我仍然無法將數據保存到mysql數據庫。 – user6181358
