Font Size

For controls that can display text (such as textview edittext radiobutton button checkbox chronometer), you sometimes need to control the font size. The Android platform defines three font sizes.

"? Android: ATTR/textappearancelarge"

"? Android: ATTR/textappearancemedium"

"? Android: ATTR/textappearancesmall"

Usage:

Android: textappearance = "? Android: ATTR/textappearancelarge"
Android: textappearance = "? Android: ATTR/textappearancemedium"
Android: textappearance = "? Android: ATTR/textappearancesmall"

Or

Style = "? Android: ATTR/textappearancelarge"
Style = "? Android: ATTR/textappearancemedium"
Style = "? Android: ATTR/textappearancesmall"

Font color

Android: textcolor = "? Android: ATTR/textcolorprimary"
Android: textcolor = "? Android: ATTR/textcolorsecondary"
Android: textcolor = "? Android: ATTR/textcolortertiary"

Android: textcolor = "? Android: ATTR/textcolorsecondaryinverse"
