android报表图形引擎(AChartEngine)demo解析与源码

AchartEngine支持多种图表样式，本文介绍两种：线状表和柱状表。 AchartEngine有两种启动的方式：一种是通过ChartFactory.get***View()方式来直接获取到view放入到我们设置好的布局文件中，还有一种是通过ChartFactory.get***Intent()来获得启动activity的intent（需要在AndroidManifest.xml中注册一个activity：org.achartengine.GraphicalActivity）。 需有添加jar包：achartengin.jar，可以到http://code.google.com/p/achartengine/downloads/list这个地址去下载，也可以下地我写的demo的源码，libs文件夹里有。 先上两张效果图： 代码如下： 线状图布局文件： [html] <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context=".LineChartBuilder" > <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/hello_world" /> <LinearLayout android:id="@+id/chart" android:orientation="horizontal" android:layout_height="fill_parent" android:layout_width="fill_parent" ></LinearLayout> </RelativeLayout> [/html] 主布局文件 [html] <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <Button android:id="@+id/lineButton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="50dp" android:layout_gravity="center_horizontal" android:text="线状图" /> <Button android:id="@+id/barButton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginTop="10dp" android:layout_gravity="center_horizontal" android:text="柱状图" /> </LinearLayout> [/html] 线状图主要代码： [java] public class LineChartBuilder extends Activity { private XYMultipleSeriesDataset mDataset =new XYMultipleSeriesDataset();
