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] [/html] 主布局文件 [html] [/html] 线状图主要代码： [java] public class LineChartBuilder extends Activity { private XYMultipleSeriesDataset mDataset =new XYMultipleSeriesDataset(); private XYMultipleSeriesRenderer mRenderer =new XYMultipleSeriesRenderer(); private XYSeries mCurrentSeries; private XYSeriesRenderer mCurrentRenderer; private String mDataFormatString; private GraphicalView mChartView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.line_chart); //设置图表的属性 String seriesTitle="玩家年龄趋势"; XYSeries series =new XYSeries(seriesTitle); mDataset.addSeries(series); mCurrentSeries=series; XYSeriesRenderer seriesRenderer=new XYSeriesRenderer(); seriesRenderer.setColor(Color.GREEN); seriesRenderer.setFillBelowLine(true); seriesRenderer.setFillBelowLineColor(Color.RED); seriesRenderer.setFillPoints(true); seriesRenderer.setPointStyle(PointStyle.POINT); seriesRenderer.setLineWidth(3.0f); mRenderer.addSeriesRenderer(seriesRenderer); mRenderer.setYAxisMin(0d); mRenderer.setYAxisMax(120d); mRenderer.setXAxisMax(24d); mRenderer.setShowGrid(true); mRenderer.setXLabels(24); mRenderer.setChartTitle("玩家年龄--24小时变化图"); mCurrentRenderer=seriesRenderer; double x=0; double y=0; int [] [] xyValues=getValues(); for (int i = 0; i < xyValues.length; i++) { x=xyValues[i][0]; y=xyValues[i][1]; mCurrentSeries.add(x, y); } } /** * 画图 */ protected void onResume() { super.onResume(); if (mChartView==null) { LinearLayout layout=(LinearLayout) findViewById(R.id.chart); mChartView=ChartFactory.getLineChartView(this, mDataset, mRenderer); layout.addView(mChartView,new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT)); }else { mChartView.setBackgroundResource(R.id.chart); mChartView.repaint(); } } /** * 拆线点的坐标 * @return */ private int[][] getValues(){ int [][] xyValues={{ 0, 88 }, { 1, 79 }, { 2, 75 }, { 3, 71 }, { 4, 90 }, { 5, 88 }, { 6, 66 }, { 7, 65 }, { 8, 50 }, { 9, 78 }, { 10, 67 }, { 11, 77 }, { 12, 79 }, { 13, 85 }, { 14, 89 }, { 15, 93 }, { 16, 95 }, { 17, 99 }, { 18, 66 }, { 19, 55 }, { 20, 44 },{24,30}}; return xyValues; } } [/java] 主界面和柱状图主要代码： [java] public class ChartBuilder extends Activity { private XYMultipleSeriesDataset dataset; private XYMultipleSeriesRenderer renderer; private Button lineButton; private Button barButton; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.chart_builder); lineButton = (Button) findViewById(R.id.lineButton); lineButton.setOnClickListener(onButtonClickListener); barButton = (Button) findViewById(R.id.barButton); barButton.setOnClickListener(onButtonClickListener); } private OnClickListener onButtonClickListener = new OnClickListener() { @Override public void onClick(View v) { if (v.getId() == R.id.lineButton) { startLineChart(); } if (v.getId() == R.id.barButton) { startBarChart(); } } }; private void startLineChart() { Intent intent = new Intent(); intent.setClass(this, LineChartBuilder.class); startActivity(intent); } private void startBarChart() { renderer = this.getBarRenderer(); dataset = this.getBarDataset(this.getMoney()); initNames(); Intent intent = ChartFactory.getBarChartIntent(this, dataset, renderer, org.achartengine.chart.BarChart.Type.DEFAULT); startActivity(intent); } private XYMultipleSeriesRenderer getBarRenderer() { XYMultipleSeriesRenderer renderer = new XYMultipleSeriesRenderer(); SimpleSeriesRenderer simpleRenderer = new SimpleSeriesRenderer(); simpleRenderer.setColor(Color.RED); renderer.addSeriesRenderer(simpleRenderer); this.setCharSettings(renderer); return renderer; } /** * 设置描绘器的属性 * @param renderer */ private void setCharSettings(XYMultipleSeriesRenderer renderer) { renderer.setChartTitle("个人收入表"); renderer.setXTitle("姓名"); renderer.setYTitle("金额"); renderer.setXAxisMin(0.5); renderer.setXAxisMax(10.5); renderer.setBarSpacing(0.5); renderer.setYAxisMin(0); renderer.setYAxisMax(10000); renderer.setYLabelsAlign(Align.RIGHT); renderer.setDisplayChartValues(true); renderer.setShowGrid(true); renderer.setXLabels(0); renderer.setXLabelsAlign(Align.CENTER); renderer.setPanEnabled(true, false); } /** * 适配数据到数据集XYMultipleSeriesDataset * @param moneys * @return */ private XYMultipleSeriesDataset getBarDataset(double[] moneys) { XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset(); CategorySeries series = new CategorySeries("2013年3月金额"); for (int i = 0; i < moneys.length; i++) { series.add(moneys[i]); } dataset.addSeries(series.toXYSeries()); return dataset; } /** * y轴上的数值 * @return */ private double[] getMoney() { double[] moneys = { 1500, 2000, 4000, 4500, 5000, 6000, 7600, 8000, 9100, 9500 }; return moneys; } /** * x轴下面的label名称 */ private void initNames() { String[] names = { "张三", "李四", "王五", "刘六", "肖七", "周一", "杨二", "袁八", "封九", "潘十" }; for (int i = 0; i < names.length; i++) { renderer.addTextLabel(i+1, names[i]); } } } [/java] 源码下载地址：http://download.csdn.net/detail/homg92/6216873 源码用utf-8编码 获得intent和view的方法介绍：
