activity 中找到控件： KView mMyChartsView = (KView) findViewById(R.id.kview);

最主要的是数据的显示，数据 mode 的封装，主要封装在 MarketChartData 中：结构如下：

public class MarketChartData { long time = 0; double openPrice = 0; double closePrice = 0; double lowPrice = 0; double highPrice = 0; double vol = 0;

public MarketChartData() {

}

public long getTime() {
    return time;
}

public String getTime2() {
    SimpleDateFormat sdf = new SimpleDateFormat("HH:mm");
    return sdf.format(time*1000);
}
public String getTime3() {
    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    return sdf.format(time*1000);
}
public String getTime4() {
    SimpleDateFormat sdf = new SimpleDateFormat("MM-dd");
    return sdf.format(time*1000);
}
public void setTime(long time) {
    this.time = time;
}

public double getOpenPrice() {
    return openPrice;
}

public void setOpenPrice(double openPrice) {
    this.openPrice = openPrice;
}

public double getClosePrice() {
    return closePrice;
}

public void setClosePrice(double closePrice) {
    this.closePrice = closePrice;
}

public double getLowPrice() {
    return lowPrice;
}

public void setLowPrice(double lowPrice) {
    this.lowPrice = lowPrice;
}

public double getHighPrice() {
    return highPrice;
}

public void setHighPrice(double highPrice) {
    this.highPrice = highPrice;
}

public double getVol() {
    return vol;
}
public void setVol(double vol) {
    this.vol = vol;
}

}

new 个数组装载 model 数据： private List marketChartDataLists = new ArrayList(); 你的 activity 界面请求 json 数据,封装在这个模型中，在代码中添加

  mMyChartsView.setOHLCData(marketChartDataLists);
  mMyChartsView.postInvalidate();

  就能将图表数据显示出来

  主要方法：
        mMyChartsView.setClose();//关闭指标
        mMyChartsView.setMACDShow();//显示 macd
        mMyChartsView.setKDJShow();//显示 kdj

网络接口封住了，以下是 json 格式的数组，可以写入本地，加载本地数据显示效果，数组数据 0-5 依次为：时间戳，最低价，最高价，开盘价，收盘价，成交量 对应设置好 MarketChartData 模型数据，就能显示 { "des": "", "isSuc": true, "datas": [ [ 1473538260000, 4158.18, 4158.18, 4157.17,
