1.看一下 log 到底哪裡錯了。
2.為何要用 int 及 double 而不用 float ?
3.我猜是因為你輸入小數點的問題而造成 parseInt 拋出異常。
作者: jacy008723 時間: 2013-5-5 20:39
所以只要把int double 改成float就可以了嗎?
感謝大大的提點 馬上試試看

修改完之後 按下第二個按鈕沒反應
然後只輸入華氏那一欄 按第二個轉換當機 跳出

沒有 logcat ? 有的話應該很清楚問題 在哪邊吧.
作者: whl 時間: 2013-5-6 08:35
你貼出來的程式是不是有刪過？怎麼沒看到 setonClicklistener?
作者: jacy008723 時間: 2013-5-6 08:54
是的 我有刪
我先貼 logcat 給你看看

這就是問題點，212.0並不是整數，所以丟出來異常。

基本上, 你的程式好像不只一個錯誤, 另外把你的 Layout xml 放上來吧.

我現在發現只要不是整數就會當機
但是把度C轉成度F的"度F"那個數值用成整數不就不能使用小數點了?
有辦法從度C轉成度F為小數，小數再轉回度C嗎?
作者: clotai 時間: 2013-5-6 19:01
所有轉換都用 float 轉, 而不是用 Integer.parseInt,
使用 Float.parseFloat

感謝大大的指導
小弟已經成功了
不會當機嚕^^
