## Introduction
-Android has two main TextViews; one of them is **AppCompatTextView**, which has been available for quite a while, and **MaterialTextView** (which extends AppCompatTextView). They are identical, with the latter allowing a line height attribute to be set in a textAppearance (if you don’t know what that means, no worries). ***Go with MaterialTextView**.*

They are identical, with the latter allowing a line height attribute to be set in a textAppearance (if you don’t know what that means, no worries). _**Go with MaterialTextView**._
With Android 9.0 Pie, Google introduced 3 new attributes for TextViews: *firstBaselineToTopHeight*, *lastBaselineToBottomHeight* and *lineHeight*. These control everything you’d need to build a UI with.
-However, if you seek fidelity, you’ll find that ***lineHeight*** on Android differs from other platforms and most design tools.
+However, if you seek fidelity, you’ll find that _**lineHeight**_ on Android differs from other platforms and most design tools.
## How is it any different?
Let us take a look at some examples; one with a single line, then two lines, then three lines with line height set to 24pt/sp.

As you can probably tell, Android TextViews are always smaller than the ones given to a developer from a design tool and those implemented on the web. In reality, Android’s lineHeight is not line-height at all! **It’s just a smart version of line-spacing.**
-
+
-
+
Now you might ask yourself, “*How can I calculate the height of each TextView, then?*”
When you use a TextView, it has one parameter turned on by default: **includeFontPadding**. includeFontPadding increases the height of a TextView to give room to ascenders and descenders that might not fit within the regular bounds.
-

Now that we know how Android’s typography works, let’s look at an example.
Here’s a simple mockup, detailing the spacing between a title and a subtitle. It is built at 1x, with Figma, meaning line height defines the final height of a text box — not the text size. (This is how most design tools work)

*Of course, because it’s Android, the line height has no effect on the height of the TextView, and the layout is therefore 8dp too short of the mockups.*

Unfortunately, translating values from a design tool wasn’t possible. You had the option to either pixel nudge (pictured above, right), or forget about alignment altogether thus leading to an incorrect implementation that would, yet again, be shorter than the mockups.

*firstBaselineToTopHeight* and *lastBaselineToBottomHeight* are powerful tools for Android design. They do as the name suggests: If *firstBaselineToTopHeight *is set to 56sp, then that’ll become the distance between the first baseline and the top of a TextView.

This means that designers, alongside developers, can force the bounds of a TextView to match the design specs and open the door to perfect implementations of their mockups.

In reality, the new attributes were actually made to be used when creating layouts: you want to make sure the baseline is a certain distance from another element, and it also helps to align the first and lastBaseline to a 4dp grid. This mirrors the way iOS layouts are built.

As you might imagine, **if we want to keep our text aligned to a baseline grid, we need to ensure that the height of each TextView is a multiple of 4 while doing so.** This means we must apply first and lastBaseline attributes to both / all of the stacked TextViews — and that becomes hard to maintain.

+Ultimately, overriding first and lastBaseline in layouts also causes major issues if you want to change a font style or text size in the future.
