arcCanvas.java

    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);

        mPaint.setStyle(Paint.Style.STROKE);
        mPaint.setStrokeWidth(50);
        // Setting the color of the circle
        mPaint.setColor(Color.BLUE);

        // Draw the circle at (x,y) with radius 250
        int radius = 250;
        canvas.drawCircle(mX, mY, radius, mPaint);

        mPaint.setColor(Color.YELLOW);
        mPaint.setDither(true);                    // set the dither to true
        mPaint.setStyle(Paint.Style.STROKE);       // set to STOKE
        mPaint.setStrokeJoin(Paint.Join.ROUND);    // set the join to round you want
        mPaint.setStrokeCap(Paint.Cap.ROUND);      // set the paint cap to round too
        mPaint.setPathEffect(new CornerPathEffect(50) );   // set the path effect when they join.
        mPaint.setAntiAlias(true);

        RectF oval = new RectF(mX - radius, mY - radius, mX + radius, mY + radius);
        canvas.drawArc(oval, -90, 90, false, mPaint);
        mPaint.setColor(Color.RED);
        canvas.drawArc(oval, -90, 89, false, mPaint);
        // Redraw the canvas
        //invalidate();
