android学习：模拟微博看看界面
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
這幾天學會了ListView組件，這個組件真的很有用。希望在今后的開發中能大量用到。

通過ListView的學習，模擬了新浪微博的隨便看看頁面。
要實現的效果：
代碼如下：
[html] view plaincopyprint?????????? layout_view.xml
?????????
??? 代碼如下：
[html] view plaincopyprint?5.java代碼
???????? MainActivity.java
[html] view plaincopyprint???????????? ArticleAdapter.java
[html] view plaincopyprint?????????? Messages.java
[html] view plaincopyprint?總結
