Android開源框架ImageLoader的完美例子

2013年8月19日開源框架之Universal_Image_Loader學習

很多人都在討論如何讓圖片能在非同步載入更加流暢，可以顯示大量圖片，在拖動ListView的時候不會出現卡的現象。關於ImageLoader這個開源框架的使用有很多網友都介紹過，不過還不夠清楚，這裡有一個關於這個開源專案的完美例子，ListView的圖片載入、GridView的圖片載入、ViewPager的圖片載入、Gallery畫廊的圖片載入、Widget的使用。很完善的一個例子，在這裡我把所有介面效果做出部落格分享出來，需要原始碼的朋友到我的資源頁下載

要使用ImageLoader就要到這裡下載jar包：

然後匯入專案中去就行了

專案文件結構圖：

從介面說起，介面本身是沒什麼好說的，就是如何在xml當中進行定義罷了

有以下這麼多個佈局檔案

一個一個來看唄

首先是這樣的效果

這個在Android4.2.2比較好看，在Android2.3.3就顯得比較挫。
