推荐答案

行间距由它的高度乘以行乘数和一个额外的间距。这会给你一个TextView的路线linespacing：

Line spacing consists of its height multiplied by line multiplier and an extra spacing. This will give you linespacing of a TextView's line:

textView.getPaint().getFontSpacing() * textView.getLineSpacingMultiplier() + textView.getLineSpacingExtra();

但是，请记住，您可以利用getLineSpacingMultiplier（）和getLineSpacingExtra的（）仅适用于API级别的方法+ 16

However, keep in mind that you can make use of the getLineSpacingMultiplier() and getLineSpacingExtra() methods only for API level 16+.
