解决方案

这里是你的需求的工作代码....

code： -

  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; 
 //示例值
 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....

I want to draw this type of circle in my application. I am able to draw circle using Canvas but I can't get any idea about how to make partitioned?

Can anyone suggest me how can I make partitioned of circle?

Edit:- I want to draw line that are in inner circle.

Thanks in advance.

解决方案

Here's the working code for your requirement....

Editing the code:-

    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);

I hope now you satisfy with my answer....
