Cara merubah orientasi layar menjadi Landscape di Video Player Android Studio - How to Change Screen Orientation in Android Studio 1.4 Video Player



Ternyata setelah sempat beberapa hari mencoba beberapa trik dari netters belum ada yang bisa merubah layar aplikasi android menjadi LANDSCAPE.

Mulai dari beberapa forum yang menyarankan untuk merubah file Manifest, tetap tidak bisa juga
akhirnya "hanya" sebaris kode ini dapat merubahnya.. Just use this code and then Boommm...SCREEN_ORIENTATION_USER_LANDSCAPE.


//This
 setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_USER_LANDSCAPE);
//End

Untuk memastikan kode ini dapat berjalan dengan baik di pemutar video, kamu bisa menggunakannya di baris kode setelah ..

//This
mContentView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE
                    | View.SYSTEM_UI_FLAG_FULLSCREEN
                    | View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                    | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
                    | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                    | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION)
//End

Atau lebih lengkapnya untuk file FullscreenActivity.java


//This

Selamat mencoba..
Note:
- jika kita hanya gunakan SCREEN_ORIENTATION_LANDSCAPE bukan SCREEN_ORIENTATION_USER_LANDSCAPE, maka user tidak bisa melakukan auto rotate layar waktu fullscreen, meskipun setting di smartphone nya sudah auto


Good Luck All
and keep trying..
