Android通訊錄管理(獲取聯系人、通話記錄、短信消息)(二)
前言:上一篇博客介紹的是獲取聯系人的實現,本篇博客將介紹通話記錄的實現。

代碼是最好的解釋了,這裡使用的幾個重要的類,一個是Uri(進行查詢的通用資源標志符),一個是AsyncQueryHandler(Android提供的異步操作數據庫的類),這裡我們調用它的startQuery方法來查詢數據庫,在它onQueryComplete方法中得到數據庫返回的游標cousor,通過curor來取得數據庫對應表中的字段值。
應用市場很多應用程序中都會看見一些數字紅點提示的效果,如QQ、微信以及一些提示更新應用的APP,以達到更好的提示功能的應用,本文將介紹一開源控件的使用實現紅點更新信息提示
在介紹本文動畫效果實現之前,先來介紹屬性動畫相關的幾個知識點。ValueAnimator與ObjectAnimator。 Interpolator插值器與TypeEval
開發App過程中,免不了要進行網絡請求操作進行數據交換,比如下載圖片,如果自己寫一個下載圖片的類進行操作的話,要考慮太多太多內容,必須線程池,內存溢出,圖片磁盤緩存操作,
1. UiObejct.getFromParent()的用法:從這個名字就知道,就是從當前對象的父對象中查找想要的子對象,該子對象和當前對象應該是同一層級。如上圖所示:M
