personalize strikeThrough Textview

Question

I use this to have stike through a textView

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

but now I wanna personalize the color and rotate it 45° to fit the diagonal of the content.

What I tied:

I though about extending the textview widget and override onDraw method .. but I'm very beginner at designing ...

so any help how to draw the red(color) rotated line on the textView ?

@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);
}
