hi guys: I am looking for schematic for SSD1306 128x32 and 128x64 schematic.(eagle file will be the best). Is anyone know the links or something like that? I have been googling for a while. I just couldn't find it.

User 0miker0 created several custom pcb's for this display (he finished at least one). Read a bit about that in this (a bit lengthy) thread. I think he has a link to schematics in there. Or you can ask him directly if he allows you to send PM.
