我只是嘗試了一切..凍結
什麼我的代碼不會從用戶以信息，並將其上傳到數據庫中..
所以錯誤狀態：應用程序時，點擊複選框
05-12 12:20:19.721: E/AndroidRuntime(688): java.lang.IllegalStateException: Could not find a method onCheckboxClicked(View) in the activity class com.example.senior.Userfilter for onClick handler on view class android.widget.CheckBox with id 'checkbox_secondhand'
這是我的代碼：

另一個問題如何發送複選框和整數的參數。謝謝
請嘗試將代碼縮小到相關部分。 –
