android - 如何使用油漆给圆圈加上边框

Question

您好，我已经实现了进度条并且工作正常，但我的问题是我需要使用油漆为圆圈提供唯一的边框。我致力于此，但它占据了圆圈的所有区域，我只需要边框。

我的绘画代码:

    mCirclePaint = new Paint();
    mCirclePaint.setAntiAlias(true);
    mCirclePaint.setDither(true);
    mCirclePaint.setColor(mCircleColor);
    mCirclePaint.setStrokeWidth(mCircleStrokeWidth);
    mCirclePaint.setStyle(Paint.Style.STROKE);
    mCirclePaint.setStrokeJoin(Paint.Join.MITER);
    // mCirclePaint.setShadowLayer(4.0f, 0.0f, 2.0f, Color.BLACK);
    mCirclePaint.setStrokeCap(Paint.Cap.SQUARE);
    canvas.drawPath(mCirclePath, mCirclePaint)

Answer 1

试试这个，

paint = new Paint();
paint.setColor(Color.GREEN);        
paint.setStrokeWidth(2);            
paint.setStyle(Paint.Style.STROKE);         
canvas.drawCircle(0, 0, (float) (width1/(1.4)), paint);
