本樣本基於網友現有安卓項目人肉翻譯,在Xamarin中替換和修改了很多方法的命名,比如某些屬性需要去掉getName的get首碼, 有些方法名稱需要使用Pascal命名法替換Java的Camel 命名規範

另外在內部類的使用方式上也有一些區別,但是整體上來說,大部分的方法名稱都與Java 原版Android一致,所以如果有現有的Android 項目需要轉換到Xamarin 還是很容易的.此處給Xamarin 66個贊

 參考Java版本:http://blog.csdn.net/wxdjaqgs/article/details/44561101

博主提供了源碼下載

我所做的只是將需要的圖片檔案貼過來.然後開始翻譯代碼

 

由於IOS品台的打包流程還沒有去研究,所以本次實驗沒有使用ios 測試.以後有時間補上

 

 

 

PS:全篇無注釋(別問我,打死都不會說的 - -!)

 

 

貼代碼:
