在KLineChartView声明一个接口回调，重写onSingleTapUp

@Override public boolean onSingleTapUp(MotionEvent e) { if(childClickListener != null){ if(getChildCount() >= 1 && getChildRect() != null){ int x = (int) e.getX(); int y = (int) e.getY(); if(getChildRect().contains(x,y)){ childClickListener.childClick(); } } } return super.onSingleTapUp(e); }
