遇到的问题

问题一:

  无法画虚线

解决:

Paint xuLinePaint = new Paint();
		xuLinePaint.setStyle(Paint.Style.STROKE);
		xuLinePaint.setColor(Color.parseColor("#fc5a9c"));
		PathEffect effects = new DashPathEffect(new float[]{5,5,5,5},1);  
		xuLinePaint.setPathEffect(effects);

 

 path.moveTo(initPointX, initPointY); // from
								 path.lineTo(pointX, pointY); // to
								 canvas.drawPath(path, xuLinePaint);

 

问题二:不能初始化的时候就指定滑动的位置,无法滑动,用scrollTo()方法,滚动过的区域无法正常绘制了。真是纠结!

new Handler().postDelayed(new Runnable() {
			
			@Override
			public void run() {
////				chartView.scrollTo(-1000, 0);
				if (todayPosition > 7) {
					chartView.offsetLeftAndRight(-(70 * (todayPosition - 5)));
				}
////				chartView.invalidate();
			}
		}, 500);

 一定要等待绘制完毕后再执行,否则无效!
