If you want to fix the orientation of one Activity in your project, you have to open the Manifest.xml and put in the section of parameters of the desired Activity (before the closure of the first tag < activity…> ):

android:screenOrientation="portrait" if you want VERTICAL fixed orientation

android:screenOrientation="landscape" if you want HORIZONTAL fixed orientation
