垂直对齐TextView中由HTML定义的图像 [英] Vertically align images defined by HTML in TextView

问题描述

我有一个 TextView ，其中包含html中的文字和图片，即带有< img src = \的一些文字你好\/> image。

要正确显示图像，请使用 Html.ImageGetter 请求的资源可绘制并根据 TextView 的高度设置其边界。

目前看起来图像与基线对齐 TextView ，而我希望它们垂直居中显示。是否可能以及如何？

I have a TextView containing text and image(s) in html, i.e. "some text with <img src=\"hello\"/> image".
To display images properly the Html.ImageGetter is used, which reads the requested drawable from resources and sets its bounds according on the TextView's height.
Currently it looks like the images are aligned to the baseline of the TextView, while I would like them to appear vertically centered. Is it possible and how?
