android - 个性化 strikeThrough Textview

Question

我用它来浏览 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。

我绑的是什么:

虽然我想扩展 textview 小部件并重写 onDraw 方法..但我是设计的初学者...

那么对于如何在 textView 上绘制红色(颜色)旋转线有什么帮助吗？

@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);
}
