Kind of, I can change the settings, but the keyboard is mostly the same, but the word prediction is in spanish.
settings - language and input - android keyboard(icon next to it) - and then input languages - uncheck system languages - check spanish - then uncheck english
About as close as I can get it for you so far.
Are you just wanting the keyboard to be in spanish or everything?
If you want everything in Spanish,
settings - language and input - language - click espanol
