overridePendingTransition ~ 頁面切換的動畫效果

類似Microsoft Office PowerPoint的動畫效果, 除了Android內建的
(實現淡入淡出的效果)android.R.anim.fade_in, android.R.anim.fade_out;
(由左向右滑入的效果)android.R.anim.slide_in_left, android.R.anim.slide_out_right
我們更可在res/建立anim/來自行定義動畫

本範例建立5個button分別以不同的anim開啟Animation.java, 後點擊任意處回到Main_Activity.java, 結束一個動畫的展現.
