android 自定義餅圖
阿新 • • 發佈：2018-12-31
本程式碼是一年前公司專案需要自己所寫,當時做android專案需要統計的功能，統計的圖表包括餅圖、柱狀圖、折線圖，程式碼寫的有些笨拙！希望大家能夠看懂！其程式碼做拋磚引玉，希望大家能夠再改寫下！可以用多執行緒做出動畫，是不是更好呢？這些後期我也沒有整理過，所以誰能再整理下！

不能把全部程式碼粘貼出來望諒解！涉及到公司的利益
用法
/**波段金額比例**/
private Cookie mCkAddBangAmount;
/**波段數量比例**/
private Cookie mCkAddBangQuantity;
/**大類金額比例**/
private Cookie mCkAddTypeAmount;
/**大類數量比例**/
private Cookie mCkAddTypeQuantity;
/**預期和實際對比**/
private LineHistogram mHgAddContrast;
方法操作
