Java 如何在android中创建自定义形状：跨圆

我想画一个圆圈，然后在android中使用Shape drawable，就像

如果有人知道如何实现这一目标。请帮忙。我无法在圆内创建十字

使用这个代码

    class MyView extends View {
              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;
    @Override
        protected void onDraw(Canvas canvas) {
            super.onDraw(canvas);
                // Example values
                rect.set(getWidth() / 2 - mRadius, getHeight() / 2 - mRadius,
                        getWidth() / 2 + mRadius, getHeight() / 2 + mRadius);
                paint1.setColor(Color.RED);
                paint1.setStrokeWidth(16);
                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.RED);
                paint3.setStrokeWidth(16);
                paint3.setAntiAlias(true);
                paint3.setStrokeCap(Paint.Cap.BUTT);
                paint3.setStyle(Paint.Style.STROKE);
                canvas.drawArc(rect, 0, 3600, false, paint1);

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

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

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

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