Question

我在画布上画了一个圆圈然后我在它上面绘制另一个形状，最终的结果应该是我需要绘制的新形状在我正在绘制的第一个圆圈下面

有没有办法可以将旧圆圈的高度再次改为顶部？

我不想在所有内容上绘制另一个圆圈，因为我想将此功能调用3次，每秒4次

这是我的班级：

Paint ciclePaint = new Paint();
        ciclePaint.setColor(getResources().getColor(R.color.cicleShapeOutline));
        ciclePaint.setStrokeWidth(40f);
        ciclePaint.setStyle (Paint.Style.STROKE);

        Paint innerCiclePaint = new Paint();
        innerCiclePaint.setColor(getResources().getColor(R.color.cicleShapeOutline));
        innerCiclePaint.setStrokeWidth(3f);
        innerCiclePaint.setStyle (Paint.Style.STROKE);

        canvas.drawCircle(getWidth()/2f, getHeight()/2f, (600f), ciclePaint);

        canvas.drawCircle(getWidth()/2f, getHeight()/2f, (450f), innerCiclePaint);

        canvas.drawCircle(getWidth()/2f, getHeight()/2f, (300f), innerCiclePaint);

        canvas.drawCircle(getWidth()/2f, getHeight()/2f, (150f), innerCiclePaint);



        //THIS NEEDS TO SHOW BEFORE THE THREE CIRCLES

        Paint canvasFillForTestings = new Paint();
        canvasFillForTestings.setColor(getResources().getColor(R.color.colorAccent));

        canvas.drawPath( pathsArray.get(7), canvasFillForTestings);

您必须在圆圈之前绘制新形状以显示在下方。 z顺序取决于绘图顺序。

绘图后如何在画布中更改Z的圆形高度？
