android - 如何在android中绘制带有分区的圆圈？

Question

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

谁能建议我如何分割圆圈？

编辑:- 我想在内圈画线。

提前致谢。

这是满足您要求的工作代码....

编辑代码:-

    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);

现在我希望你对我的回答感到满意....
