how to reduce the font size in Grid view in Android?

Hi I am new to android.I just create the Gri开发者_StackOverflowd view by using java code(not using xml design) I need to reduce the font size of the Grid view .How to do this ?

GridView does not have a font size, because GridView does not have a font, because GridView does not have any text.

If you are putting text into cells of a GridView by some sort of Adapter, then you need to modify your Adapter -- or the layout it is using for the cells -- to use a different font size.
