Get the height of a block of text constrained to a max width.

GetTextHeight.java

	public static int getTextHeight(String text, int maxWidth, float textSize, Typeface typeface) {
		TextPaint paint = new TextPaint(Paint.ANTI_ALIAS_FLAG | Paint.SUBPIXEL_TEXT_FLAG);
		paint.setTextSize(textSize);
		paint.setTypeface(typeface);

		int lineCount = 0;

		int index = 0;
		int length = text.length();

		while(index < length - 1) {
			index += paint.breakText(text, index, length, true, maxWidth, null);
			lineCount++;
		}

		Rect bounds = new Rect();
		paint.getTextBounds("Py", 0, 2, bounds);
		return (int)Math.floor(lineCount * bounds.height());
	}

It helped me today too :)
