XYMultipleSeriesRenderer 绘制K线图，点击弹出pop

本文是讲述如何使用XYMultipleSeriesRenderer绘制K线图，并且点击弹出pop的实例，由于是从项目中摘出来的，所有只有主要代码并不是完成能够直接运行的程序。

首先：绘制K线图，并设置其相关属性

变量：

    private LinearLayout containerbody;private GraphicalView mLineChartView;private PopupWindow mPopupWindow;private PopupWindow mPopupWindow1;private PopupWindow popWin;private View mPopupView;private View mPopupView1;private TextView mPopTxt1;private TextView mPopTxt2;private TextView mPopTxt3;private TextView mPopTxt4;private XYSeries series;private final int CHART_MARGINS_LEFT = 20;private final int CHART_MARGINS_TOP = 30;private final int CHART_MARGINS_RIGHT = 20;
//    private final int CHART_MARGINS_BOTTOM = 0;private int chart_margins_bottom;private final int CHART_X_LABELS = 9;private final int CHART_Y_LABELS = 6;private final int CHART_X_AXISMAX = CHART_X_LABELS + 1;private final int CHART_Y_AXISMAX = CHART_Y_LABELS * 10;private int panXLimit;private int lineEndX;private int mEventStartX;
//    private int mEventStartY;private int mEventEndX;private int mEventEndY;private int mScreenOffsetX = 0;
//    private int mScreenOffsetY = 0;private int POPWIN_WIDTH ;private int POPWIN_HEIGHT;private int POPWIN_WIDTH1 ;private int POPWIN_HEIGHT1;

initChartView:

private void initChartView(){System.out.println("initChartView here !");// 1, 构造显示用渲染图XYMultipleSeriesRenderer renderer = new XYMultipleSeriesRenderer();
//  renderer.setPointSize(5);// 2,进行显示XYMultipleSeriesDataset dataset = new XYMultipleSeriesDataset();// 2.1, 构建数据series = new XYSeries("业绩曲线");// 填充数据System.out.println("initChartView here !lineEndX = " + lineEndX);for (int x = 0; x < lineEndX; x++){// 填x,y值mDataMap = mDataMapList.get(x);// X轴从1开始，所以x+1series.add(x + 1, Integer.parseInt(mDataMap.get("BUSTOTAL")));
//   series.add(x + 1, (int) Math.abs(Math.random() * CHART_Y_AXISMAX));System.out.println("x = " + (x + 1) + " | y = " + Integer.parseInt(mDataMap.get("BUSTOTAL")));}// 需要绘制的点放进dataset中dataset.addSeries(series);// 3, 对点的绘制进行设置XYSeriesRenderer xyRenderer = new XYSeriesRenderer();// 3.1设置K 线颜色xyRenderer.setColor(Color.RED);// 3.2设置点的样式xyRenderer.setPointStyle(PointStyle.CIRCLE);xyRenderer.setFillPoints(true);//设置线的宽度xyRenderer.setLineWidth(3);// 3.3, 将要绘制的点添加到坐标绘制中renderer.addSeriesRenderer(xyRenderer);// 4, 设置图表属性// 显示网格renderer.setShowGrid(true);// 设置4周边距chart_margins_bottom = (int) getResources().getDimension(R.dimen.chart_margin_bottom);renderer.setMargins(new int[] { CHART_MARGINS_TOP, CHART_MARGINS_LEFT, chart_margins_bottom, CHART_MARGINS_RIGHT });// 边框外侧颜色
//  renderer.setMarginsColor(Color.argb(0, 0xff, 0, 0)); // 穿透背景色renderer.setMarginsColor(Color.WHITE);// 设置背景颜色renderer.setBackgroundColor(Color.TRANSPARENT);// 设置背景颜色生效renderer.setApplyBackgroundColor(true);// 是否支持图表移动renderer.setPanEnabled(true, false);// 坐标滑动上、下限renderer.setPanLimits(new double[]{1, panXLimit, 0, 100});// 是否支持图表缩放renderer.setZoomEnabled(false, false);// X轴等分，最小、最大坐标值renderer.setXLabels(CHART_X_LABELS);renderer.setXAxisMin(1);renderer.setXAxisMax(CHART_X_AXISMAX);// Y轴等分，最小、最大坐标值renderer.setYLabels(CHART_Y_LABELS);renderer.setYAxisMin(0);renderer.setYAxisMax(CHART_Y_AXISMAX);// 坐标轴颜色renderer.setAxesColor(Color.rgb(242, 103, 16));// 坐标轴单位文字颜色、字号renderer.setLabelsColor(Color.rgb(25, 110, 172));renderer.setLabelsTextSize(16);// 坐标轴文字对齐renderer.setYLabelsAlign(Paint.Align.RIGHT);//设置原点大小renderer.setPointSize(5);// 设置图表标题文字
//  renderer.setChartTitle(getString(R.string.chart_title));// 是否显示图例renderer.setShowLegend(false);// 生成图表视图mLineChartView = ChartFactory.getLineChartView(ShowChartActivity.this, dataset, renderer);mLineChartView.setOnTouchListener(chartViewOnTouchListener);mLineChartView.setId(0);// 添加至父容器containerbody = (LinearLayout) findViewById(R.id.container_chart);containerbody.addView(mLineChartView, new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
//  firstShowChart();}

2、监听其onTouch事件：其中，弹出pop窗口是根据项目需要弹出蓝色向左、蓝色向右、绿色向左、绿色向右四种pop.

private OnTouchListener chartViewOnTouchListener = new OnTouchListener(){@Overridepublic boolean onTouch(View v, MotionEvent event){// TODO Auto-generated method stubdismissPopupWindow();switch (event.getAction()){case MotionEvent.ACTION_DOWN:mEventStartX = (int) event.getX();
//    mEventStartY = (int) event.getY();break;case MotionEvent.ACTION_UP:// *图表点击坐标mEventEndX = (int) event.getX();mEventEndY = (int) event.getY();System.out.println("1.------------------------------");// 屏幕是否位移mScreenOffsetX += mEventEndX - mEventStartX == 0 ? 0 : mEventEndX - mEventStartX;// 是否超出X轴原点（是，归0）mScreenOffsetX = mScreenOffsetX > 0 ? 0 : mScreenOffsetX;System.out.println("############ mOffsetX = " + mScreenOffsetX);if (event.getX() < CHART_MARGINS_LEFT || event.getX() > containerbody.getRight() - CHART_MARGINS_LEFT || event.getY() < CHART_MARGINS_TOP|| event.getY() > containerbody.getBottom() - CHART_MARGINS_TOP){// out of the chartView, do nothing.}else{// 取屏幕宽、高int screenWidth = getWindowManager().getDefaultDisplay().getWidth();int screenHeight = getWindowManager().getDefaultDisplay().getHeight();// 取图表区域宽、高int chartViewWidth = mLineChartView.getWidth();int chartViewHeight = mLineChartView.getHeight();// 求图表单元格宽、高int chartCellWidth = (chartViewWidth - CHART_MARGINS_LEFT * 2) / CHART_X_LABELS;int chartCellHeight = (chartViewHeight - CHART_MARGINS_TOP - chart_margins_bottom) / CHART_Y_LABELS;// 是否超出X轴上限（是，取上限值）mScreenOffsetX = mScreenOffsetX < -chartCellWidth * (panXLimit - CHART_X_AXISMAX) ? -chartCellWidth * (panXLimit - CHART_X_AXISMAX): mScreenOffsetX;System.out.println("-chartCellWidth * panXLimit = " + -chartCellWidth * (panXLimit - CHART_X_AXISMAX));System.out.println("@@@@mScreenOffsetX = " + mScreenOffsetX);// *求图表像素坐标 换算成图表单位坐标int chartEventX = 1 + Math.round((mEventEndX - CHART_MARGINS_LEFT) / chartCellWidth);int chartEventY = CHART_Y_AXISMAX - Math.round((mEventEndY - CHART_MARGINS_TOP) / chartCellHeight * 10);System.out.println("chartEventX = " + chartEventX);System.out.println("chartEventY = " + chartEventY);// 求位移单元格int chartOffsetX = Math.round(mScreenOffsetX / chartCellWidth);System.out.println("############ chartOffsetX = " + chartOffsetX);System.out.println("2.================================");// 求图表像素坐标 换算成屏幕像素坐标     int screenEventX = mEventEndX + (screenWidth - chartViewWidth) / 2;int screenEventY = mEventEndY + (screenHeight - chartViewHeight) / 2;
//     System.out.println("chartEventX = " + event.getX());
//     System.out.println("chartEventY = " + event.getY());
//     System.out.println("screenEventX = " + screenEventX);
//     System.out.println("screenEventY = " + screenEventY);boolean mType = true;isShowPopWin: for (int i = 0; i < lineEndX; i++){int pxSeriesX = ((int) (series.getX(i)) - 1) * chartCellWidth + CHART_MARGINS_LEFT;int pxSeriesY = (CHART_Y_AXISMAX - (int) (series.getY(i))) * chartCellHeight / 10 + CHART_MARGINS_TOP;System.out.println("3.**********************************");
//      System.out.println(" mEventEndX = " + mEventEndX);
//      System.out.println(" pxSeriesX + mScreenOffsetX - chartCellWidth / 2 = " + (pxSeriesX + mScreenOffsetX - chartCellWidth / 2));
