Apps Android Navigation Drawer with activities

I downloaded android navigationdrawer project from HERE

And i wanna change ImportFragment to activity and set it in Drawer?

Please if can anyone help me

instead of
Code:
 fm.beginTransaction().replace(R.id.content_frame, new ImportFragment()).commit();
You would use:
Code:
 Intent i = new Intent(this, ImportActivity.class)
startActivity(i);

Correct me if I am wrong as I am new to coding

-Change
