android - 个性化删除线 Textview

Question

我用它来刺激 TextView

textView.setPaintFlags(textView.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);

但现在我想个性化颜色并将其旋转 45° 以适合内容的对角线。

我绑的东西:

我想扩展textview小部件并覆盖onDraw方法..但我在设计方面非常初学者......

那么如何在textView上绘制红色(颜色)旋转线有帮助吗？

@Override
protected void onDraw(Canvas canvas) {
    Paint paint = new Paint();
    paint.setColor(strikeThroughColor);
    paint.setStyle(Paint.Style.FILL);
    paint.setFakeBoldText(true);
    paint.setStrikeThruText(true);
    paint.setStrokeWidth(strikeThroughWidth);
    paint.setFlags(Paint.ANTI_ALIAS_FLAG);
    super.onDraw(canvas);
    float width = getWidth();
    float height = getHeight();
    canvas.drawLine(width / 10, height / 10, (width - width / 10), (height - height / 10), paint);
}
