安卓实现achartengine+动态饼图+动态柱形图

构建动态柱形图，官方的API并没有提供可以借鉴的动态更新饼图的方法，考虑到数据都是活动的，不可能总是用静态数据，具体是通过定时器+Handler实现定时任务，通过Handler更新主线程UI，在更新之前要把之前的数据清除掉，否则那些数据都会被加载，最后重新绘制饼图，构建动态饼图的步骤主要分为以下四步，还需要在项目中引入AChartEngine依赖jar包，在Manifest中添加

/** Automatically generated file. DO NOT MODIFY */
package com.qiuzhping.achart;

public final class BuildConfig {
    public final static boolean DEBUG = true;
}
