dpi value of default "large", "medium" and "small" text views android
See in the android sdk directory.
In \platforms\android-X\data\res\values\themes.xml
:
<item name="textAppearanceLarge">@android:style/TextAppearance.Large</item> <item name="textAppearanceMedium">@android:style/TextAppearance.Medium</item> <item name="textAppearanceSmall">@android:style/TextAppearance.Small</item>
In \platforms\android-X\data\res\values\styles.xml
:
<style name="TextAppearance.Large"> <item name="android:textSize">22sp</item></style><style name="TextAppearance.Medium"> <item name="android:textSize">18sp</item></style><style name="TextAppearance.Small"> <item name="android:textSize">14sp</item> <item name="android:textColor">?textColorSecondary</item></style>
TextAppearance.Large
means style is inheriting from TextAppearance
style, you have to trace it also if you want to see full definition of a style.

To put it in another way, can we replicate the appearance of these text views without using the android:textAppearance attribute?
Like biegleux already said:
- small represents 14sp
- medium represents 18sp
- large represents 22sp
If you want to use the small, medium or large value on any text in your Android app, you can just create a dimens.xml
file in your values
folder and define the text size there with the following 3 lines:
<dimen name="text_size_small">14sp</dimen><dimen name="text_size_medium">18sp</dimen><dimen name="text_size_large">22sp</dimen>
Here is an example for a TextView with large text from the dimens.xml
file:
<TextView android:id="@+id/hello_world" android:text="hello world" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textSize="@dimen/text_size_large"/>
Programmatically, you could use:
textView.setTextAppearance(android.R.style.TextAppearance_Large);
