The listener is stopping too often

Question

Hi,
I'm new using Oracle Database, here is my problem:
Initializes the listener and start the database, but after this operation the listener just stops seconds after initialization. the listener only works as 4 seconds.
So, I can't initialize SQL Developer but on SqlPlus is working...
Any ideas?
Thanks :)
