CircleProgressBar 两个进度值的 圆环进度条，原谅我是个小白，只能写一写简单的自定义控件

今天又写了一个demo，带有两个进度值的 圆环进度条，原谅我是个小白，只能写一写简单的自定义控件，我会继续努力的。。先看效果图

@Override
protected void onDraw(Canvas canvas) {
    /*偏移量*/
    float dMax = (dotDiameter - maxProgressWidth)*0.5F;
    float dFirst = (dotDiameter - firstProgressWidth)*0.5F;
    float dSecond = (dotDiameter - secondProgressWidth)*0.5F;
    /*1.圆心（x,y）坐标值*/
    float centerX = (width - getPaddingLeft() - getPaddingRight()) / 2.0f;
    float centerY = (height - getPaddingTop() - getPaddingBottom()) / 2.0f;
    /*2.圆环半径*/
    float maxRadius = centerY - maxProgressWidth / 2;
    float firstRadius = centerY - firstProgressWidth / 2;
    float secondRadius = centerY - secondProgressWidth / 2;
    if (getWidth() >= getHeight()) {
        maxRadius = centerY - maxProgressWidth / 2;
        firstRadius = centerY - firstProgressWidth / 2;
        secondRadius = centerY - secondProgressWidth / 2;
    } else {
        maxRadius = centerX - maxProgressWidth / 2;
        firstRadius = centerX - firstProgressWidth / 2;
        secondRadius = centerX - secondProgressWidth / 2;
    }
    maxRectF.left =  centerX - maxRadius + dMax;
    maxRectF.right = centerX + maxRadius - dMax;
    maxRectF.top = centerY - maxRadius + dMax;
    maxRectF.bottom = centerY + maxRadius - dMax;
    firstRectF.left =  centerX - firstRadius + dFirst;
    firstRectF.right = centerX + firstRadius - dFirst;
    firstRectF.top = centerY - firstRadius + dFirst;
    firstRectF.bottom = centerY + firstRadius - dFirst;
    secondRectF.left = centerX - secondRadius + dSecond;
    secondRectF.right = centerX + secondRadius - dSecond;
    secondRectF.top = centerY - secondRadius + dSecond;
    secondRectF.bottom = centerY + secondRadius - dSecond;
    canvas.drawArc(maxRectF, 0, 360 , false, maxProgressPaint);
    float firstAngle = (float) 360 * firstProgress / (float) maxProgress;
    float secondAngle = ((float) 360 * secondProgress / (float) maxProgress);
    float dotAngle =  (float) (Math.PI*secondAngle/180.0F);
    canvas.drawArc(firstRectF, 0 - 90, firstAngle, false, firstProgressPaint);
    canvas.drawArc(secondRectF, 0 - 90, secondAngle , false, secondProgressPaint);
    float dotCx = (float) (width*0.5 + (width - dotDiameter)*0.5 * Math.sin(dotAngle));
    float dotCy = (float) (height*0.5 - (height -dotDiameter) *0.5 * Math.cos(dotAngle));
    if(canDisplayDot){
        canvas.drawCircle(dotCx, dotCy, dotDiameter * 0.5F, dotPaint);
    }
}
