The method setOnClickListener(View.OnClickListener) in the type View is not applicable for the arguments

android新手請問setOnClickListener這句中那里錯了？系統報錯說The?method?setOnClickListener(View.OnClickListener)?in?the?type?View?is?not?applicable?for?the?arguments?(********.CalculateListener) 解決方法：

引入的類不對： import?android.content.DialogInterface.OnClickListener; 應該是View類里面的OnClickListener
