这是效果

这是代码：

private void drawCircle(Canvas c)
{
    RectF oval = new RectF(20, 20, 100, 100);

    c.drawArc(oval, -90, 180, false, getPaintWithColor(R.color.background));
    c.drawArc(oval, 90, 180, false, getPaintWithColor(R.color.font_grey));
}

private Paint getPaintWithColor(int colorId){
    Paint paint = new Paint();
    paint.setAntiAlias(true);
    paint.setDither(true);
    paint.setStyle(Paint.Style.STROKE);
    paint.setStrokeWidth(4);
    paint.setColor(getResources().getColor(colorId));

    return paint;
}
