Android仿火币K线图实现(包含MA,BOLL,MACD,KDJ,RSI,WR指标)
本项目是在 tifezh的KChartView 基础上进行修改的,新增了KDJ、WR指标、最大值和最小值展示,对UI展示进行了修改。
建议使用之前先查看常见问题
<com.github.fujianlian.klinechart.KLineChartView
android:id="@+id/kLineChartView"
android:layout_width="match_parent"
android:layout_height="match_parent" />
主图和附图初始化
// KLineChartView
private void initView() {
...
// 依次添加副图子视图
addChildDraw(mMACDDraw);
addChildDraw(mKDJDraw);
addChildDraw(mRSIDraw);
addChildDraw(mWRDraw);
// 设置成交量视图
setVolDraw(mVolumeDraw);
// 设置主视图
setMainDraw(mMainDraw);
}
BaseKLineChartView
// 主图显示隐藏调用
public void changeMainDrawType(Status status) {
if (mainDraw != null && mainDraw.getStatus() != status) {
mainDraw.setStatus(status);
invalidate();
}
}
// 主视图当前子视图
public enum Status {
MA, BOLL, NONE
}
// 设置子视图,position依据初始化添加先后顺序下标
public void setChildDraw(int position) {
if (mChildDrawPosition != position) {
if (!isShowChild) {
isShowChild = true;
initRect();
}
mChildDraw = mChildDraws.get(position);
mChildDrawPosition = position;
isWR = position == 5;
invalidate();
}
}
// 子视图隐藏
public void hideChildDraw() {
mChildDrawPosition = -1;
isShowChild = false;
mChildDraw = null;
initRect();
invalidate();
}
KLineChartView
// 是否显示为分时图
public void setMainDrawLine(boolean isLine) {
mMainDraw.setLine(isLine);
}

布局时修改KLineChartView的相关颜色即可
