編輯：關於Android編程
寫正文之前，小小的吐槽一下，還有一個月就放假了，作業、考試、還有實習（研一，下半學期課不多，也不想在實驗室）的考慮，最近基於hadoop的數據分析馬上也要驗收了，真的忙的“外焦裡嫩”啊！目前定的方向是Android開發，所以想過年來了找一個Android的實習工作，提高一點在真正的項目中的經驗。
好了，說了這麼多廢話，開始進入正題吧。
整個計步器的項目已經上傳到github上了，感興趣的朋友可以去看看（最好能給小弟我打顆星星哦~）

首先，這是兩張今天要實現的效果圖：
最主要的實現自己寫的一個HistogramView的類（柱狀圖類）
HistogramView的代碼如下：
