canvas和paint画劳力士表盘

效果图：

页面代码：{private Paint mPaint, minPaint;private float mRadius = 250;public WatchView(Context context, AttributeSet attrs) {super(context, attrs);}(Canvas canvas) {super.draw(canvas);mPaint = new Paint();mPaint.setColor(Color.BLACK);mPaint.setStyle(Paint.Style.STROKE);mPaint.setAntiAlias(true);mPaint.setStrokeWidth(8);canvas.translate(canvas.getWidth() / 2, canvas.getHeight() / 2);//把屏幕中心设为原点canvas.drawCircle(0, 0, mRadius, mPaint);//画表环canvas.drawCircle(0, 0, 8, mPaint);//画中心点canvas.drawLine(0, 20, 0, -180, mPaint);//画指针//使用path绘制路径文字Path path = new Path();//实例化路径RectF rectF = new RectF(-mRadius, -mRadius, mRadius, mRadius);//实例化一个矩形path.addArc(rectF, 180, -180);//绘制圆弧，圆弧为矩形rectF内切椭圆180°到-180°的那部分minPaint = new Paint(mPaint);//实例化新画笔minPaint.setStyle(Paint.Style.FILL);//设置实心minPaint.setTextSize(20);minPaint.setStrokeWidth(1);//设置线条粗度canvas.drawTextOnPath(count = 60;float distance = -mRadius + 20;for (int i = 0; i < count; i++) {if (i % 5 == 0) {canvas.drawLine(0, -mRadius, 0, distance + 10, minPaint);canvas.drawText(i == 0 ? “12” : String.valueOf(i / 5), -5, distance + 30, minPaint);} else {canvas.drawLine(0, -mRadius, 0, distance, minPaint);}canvas.rotate(360 / count);//旋转画纸,注意：canvas之前画的东西不会旋转，在调用rotate()后再画上的图形才会旋转}}}
