如何在android中绘制分区圈？

Question

我想在我的应用程序中绘制这种类型的圆圈。我可以使用Canvas绘制圆圈，但我不知道如何进行分区？

任何人都可以建议我如何分割圈子？

编辑： - 我想绘制内圈中的线条。

提前致谢。

以下是您的要求的工作代码....

    Paint paint1 = new Paint();
        Paint paint2 = new Paint();
        Paint paint3 = new Paint();
        Paint paint4 = new Paint();
        Paint paint5 = new Paint();
        final RectF rect = new RectF();
        int mRadius = 130;
        //Example values
        rect.set(getWidth()/2- mRadius, getHeight()/2 - mRadius, getWidth()/2 + mRadius, getHeight()/2 + mRadius); 
        paint1.setColor(Color.GREEN);
        paint1.setStrokeWidth(mRadius/2);
        paint1.setAntiAlias(true);
        paint1.setStrokeCap(Paint.Cap.BUTT);
        paint1.setStyle(Paint.Style.STROKE);
        paint2.setColor(Color.RED);
        paint2.setStrokeWidth(mRadius/2);
        paint2.setAntiAlias(true);
        paint2.setStrokeCap(Paint.Cap.BUTT);
        paint2.setStyle(Paint.Style.STROKE);
        paint3.setColor(Color.BLUE);
        paint3.setStrokeWidth(5);
        paint3.setAntiAlias(true);
        paint3.setStrokeCap(Paint.Cap.BUTT);
        paint3.setStyle(Paint.Style.STROKE);
        canvas.drawArc(rect, 0, 60, false, paint1);
        canvas.drawArc(rect, 60, 60, false, paint2);
        canvas.drawArc(rect, 120, 60, false, paint1);
        canvas.drawArc(rect, 180, 60, false, paint2);
        canvas.drawArc(rect, 240, 60, false, paint1);
        canvas.drawArc(rect, 300, 60, false, paint2);

        canvas.drawLine(getWidth()/2, 
                getHeight()/2, getWidth()/2-mRadius/2, getHeight()/2-mRadius/2,paint3);

        canvas.drawLine(getWidth()/2, 
                getHeight()/2, getWidth()/2+mRadius/2, getHeight()/2-mRadius/2,paint3);

        canvas.drawLine(getWidth()/2, 
                getHeight()/2, getWidth()/2-mRadius/2, getHeight()/2+mRadius/2,paint3);

        canvas.drawLine(getWidth()/2, 
                getHeight()/2, getWidth()/2+mRadius/2, getHeight()/2+mRadius/2,paint3);

        canvas.drawLine(getWidth()/2, 
                getHeight()/2, getWidth()/2-mRadius/4-mRadius/2, getHeight()/2,paint3);

        canvas.drawLine(getWidth()/2, 
                getHeight()/2, getWidth()/2+mRadius/4+mRadius/2, getHeight()/2,paint3);

        paint4.setColor(Color.BLACK);

        canvas.drawCircle(getWidth()/2, getHeight()/2, mRadius/2, paint4);

        paint5.setColor(Color.YELLOW);
        paint5.setStrokeWidth(3);
        paint5.setAntiAlias(true);
        paint5.setStrokeCap(Paint.Cap.BUTT);
        paint5.setStyle(Paint.Style.STROKE);
        canvas.drawCircle(getWidth()/2, getHeight()/2, mRadius/2, paint5);

我希望你现在满意我的答案......

Answer 2

我有一个想法首先使用

在分区内绘制分区

        can.drawArc(oval, startAngle, sweepAngle, useCenter, paint)

取角度值如0 t0 60，然后再次绘制另一个弧，相同的中心取角度值从60到120，依此类推。每次在Paint中设置不同的颜色。完成内圈后，几乎所有的工作都完成了。现在绘制第一个圆圈后具有相同中心但小半径的白色圆圈。因此它将创建第一个

希望它会对你有所帮助:)。

嘿，我找到了我的查询解决方案，

final RectF rect1 = new RectF();
int mWidth = this.getWidth()/2;
int mHeight = this.getHeight()/2;
int mRadius = 130, mRadius1 = 50;
rect1.set(mWidth -(mRadius-mRadius1), mHeight - (mRadius-mRadius1), mWidth + (mRadius-mRadius1), mHeight + (mRadius-mRadius1));

Paint paintLines = new Paint();
paintLines.setColor(Color.BLACK);
paintLines.setStrokeWidth((mRadius-mRadius1)/2);
paintLines.setAntiAlias(false);
paintLines.setStrokeCap(Paint.Cap.BUTT);
paintLines.setStyle(Paint.Style.STROKE);

canvas.drawArc(rect1, 0, 1, false, paintLines); 
canvas.drawArc(rect1, 30, 1, false, paintLines);
canvas.drawArc(rect1, 60, 1, false, paintLines);
canvas.drawArc(rect1, 90, 1, false, paintLines);
canvas.drawArc(rect1, 120, 1, false, paintLines);
canvas.drawArc(rect1, 150, 1, false, paintLines);
