在画布上要绘制测量文本高度（安卓） [英] Measuring text height to be drawn on Canvas ( Android )

问题描述

任何直接的方式来衡量文字的高度？ 我现在做的方法是使用涂料的measureText（）来获得的宽度，然后通过反复试验找到一个值，以得到一个近似的高度。我也一直在茫然的的FontMetrics，但所有这些看起来像吸吮近似的方法。

Any straight forward way to measure the height of text? The way I am doing it now is by using Paint's measureText() to get the width, then by trial and error finding a value to get an approximate height. I've also been messing around with FontMetrics, but all these seem like approximate methods that suck.

我想扩展事情不同的分辨率。我能做到这一点，但我结束了令人难以置信的详细code，有很多的计算，以确定相对大小。我讨厌它！必须有一个更好的办法。

I am trying to scale things for different resolutions. I can do it, but I end up with incredibly verbose code with lots of calculations to determine relative sizes. I hate it! There has to be a better way.

什么办法，一件事的时间：谢谢

Any way, one thing at a time: Thanks.
