# KLineView
股票走势图K线控件
[](https://jitpack.io/#xiesuichao/KLineView)
主图指标：MA, EMA, BOLL
副图指标：MACD, KDJ, RSI
根目录下有个apk文件夹，内有最新的测试包，可以先安装看效果
新增深度图控件，如下图所示，详情见demo
支持实时刷新最后一条数据。
支持添加最新的单条数据。
支持滑动时的分页加载更多数据。
支持惯性滑动。
支持多指触控缩放。
支持长按拖动。
支持横屏显示
支持xml布局自定义颜色，字体大小属性
已对性能做优化，总数据量十万条以上对用户体验没有影响。
首次加载5000条数据，页面初始化到加载完成，总共耗时400+ms，不超过0.5秒。
分页加载5000条数据时，如果正在滑动过程中，添加数据的那一瞬间会稍微有一下卡顿，影响不大。
经测试，800块的华为荣耀6A 每次添加4000条以下数据不会有卡顿，很流畅。
建议每次添加数据在2000条左右。
已对滑动事件冲突做处理，可上下滑动的父类（ScrollView、NestedScrollView等）无需再考虑滑动冲突
1.K线控件:
//初始化控件加载数据（仅作初始化用，数据重置请调用resetDataList）
mKLineView.initKDataList(getKDataList(5));
//设置十字线移动模式，默认为0：固定指向收盘价
mKLineView.setCrossHairMoveMode(KLineView.CROSS_HAIR_MOVE_FREE);
//分页加载时添加多条数据
mKLineView.addDataList(getKDataList(5));
//实时刷新时添加单条数据
mKLineView.addData(getKDataList(0.1).get(0));
@Override
public void onClick(View v) {
switch (v.getId()){
case R.id.btn_kline_reset:
//重置数据，可用于分时加载，是否需要定位到重置前的时间点请看方法注释
//在做分时功能重新加载数据的时候，请务必调用该方法
mKLineView.resetDataList(getKDataList(0.1));
break;
case R.id.btn_deputy:
//是否显示副图
mKLineView.setDeputyPicShow(!mKLineView.getVicePicShow());
break;
case R.id.btn_ma:
//主图展示MA
mKLineView.setMainImgType(KLineView.MAIN_IMG_MA);
break;
case R.id.btn_ema:
//主图展示EMA
mKLineView.setMainImgType(KLineView.MAIN_IMG_EMA);
break;
case R.id.btn_boll:
//主图展示BOLL
mKLineView.setMainImgType(KLineView.MAIN_IMG_BOLL);
break;
case R.id.btn_macd:
//副图展示MACD
mKLineView.setDeputyImgType(KLineView.DEPUTY_IMG_MACD);
break;
case R.id.btn_kdj:
//副图展示KDJ
mKLineView.setDeputyImgType(KLineView.DEPUTY_IMG_KDJ);
break;
case R.id.btn_rsi:
//副图展示RSI
mKLineView.setDeputyImgType(KLineView.DEPUTY_IMG_RSI);
break;
case R.id.btn_depth_activity:
//跳转到深度图页面
startActivity(new Intent(getApplicationContext(), DepthActivity.class));
break;
}
}
/**
* 当控件显示数据属于总数据量的前三分之一时，会自动调用该接口，用于预加载数据，保证控件操作过程中的流畅性，
* 虽然做了预加载，当总数据量较小时，也会出现用户滑到左边界了，但数据还未获取到，依然会有停顿。
* 所以数据量越大，越不会出现停顿，也就越流畅
*/
mKLineView.setOnRequestDataListListener(new KLineView.OnRequestDataListListener() {
@Override
public void requestData() {
//请求数据
}
});
2.深度图控件:
//添加购买数据
depthView.setBuyDataList(getBuyDepthList());
//添加出售数据
depthView.setSellDataList(getSellDepthList());
//重置深度数据
depthView.resetAllData(getBuyDepthList(), getSellDepthList());
//设置横坐标中间值
depthView.setAbscissaCenterPrice(10.265);
//设置数据详情的价钱说明
depthView.setDetailPriceTitle("价格(BTC)：");
//设置数据详情的数量说明
depthView.setDetailVolumeTitle("累积交易量：");
//设置横坐标价钱小数位精度
depthView.setPricePrecision(4);
//是否显示竖线
depthView.setShowDetailLine(true);
//手指单击松开后，数据是否继续显示
depthView.setShowDetailSingleClick(true);
//手指长按松开后，数据是否继续显示
depthView.setShowDetailLongPress(true);
