android刪除線

A. 如何改變在Android中刪除線的顏色

I think this is not possible for simple textview so you have to do the following:-
1.Create a custom TextView by extending View class
2.Declare this custom textview inside XML layout same like we do for TextView.
And at last write an onDraw() method like following.

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