Screen rotation while playing video

Question

I am playing a video and it has got a fullscreen icon.On clicking on it i am forcefully rotating the device orientation to landscape mode.But then when i rotate the screen,the video is locked into landscape mode only.It is not coming back to potrait mode.I want the video rotation to happen similar to Youtube/Hotstar app,where change of rotation happens both on button click and device orientation change.Kindly suggest some way forward.

findViewById(R.id.landscape).setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
  setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE);
    }
}
});

public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    setAutoOrientationEnabled(this,false);
}

Question:
My simple requirement is after forcefully rotating the activity using setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENS‌OR_LANDSCAPE); how can i again go back to potrait mode by rotating the device without calling setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENS‌OR_POTRAIT);

have you added `configChanges` in your manifest for the activity running the video? — not_again_stackoverflow, Sep 22 '16 at 11:46
Yes my Manifest file has this " android:configChanges="orientation|screenSize|keyboardHidden"" — Arunabha Dutta Choudhury, Sep 22 '16 at 11:49

Once you invoke this statement setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENS‌OR_LANDSCAPE); the screen is not rotating back to potrait mode even if i rotate device.The activity remains in Landscape mode only.I tried the solution you advise but it seems to have no impact — Arunabha Dutta Choudhury, Sep 22 '16 at 12:59
In a nutshell i am trying to replicate the rotation behavior of Youtube/Hotstar player — Arunabha Dutta Choudhury, Sep 23 '16 at 06:06

For the button you can just change it by using this lines :

Button buttonSetPortrait = (Button)findViewById(R.id.setPortrait);
Button buttonSetLandscape = (Button)findViewById(R.id.setLandscape);

buttonSetPortrait.setOnClickListener(new Button.OnClickListener(){

   @Override
   public void onClick(View arg0) {
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
   }

});

buttonSetLandscape.setOnClickListener(new Button.OnClickListener(){

   @Override
   public void onClick(View arg0) {
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
   }

});

Answer from : https://stackoverflow.com/a/18268304
Use the following code set the videos orientation when the device orientation changes Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig);

    // Checks the orientation of the screen
    if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
        Toast.makeText(this, "landscape", Toast.LENGTH_SHORT).show();
    } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT){
        Toast.makeText(this, "portrait", Toast.LENGTH_SHORT).show();
    }

For enable or disable auto rotate take a look at this answer: (https://stackoverflow.com/a/4909079/4585226)

import android.provider.Settings;
public static void setAutoOrientationEnabled(Context context, boolean enabled)
{
      Settings.System.putInt( context.getContentResolver(), Settings.System.ACCELEROMETER_ROTATION, enabled ? 1 : 0);
}

Add permission to the AndroidManifest.xml

<uses-permission android:name="android.permission.WRITE_SETTINGS" />

Thanx @476rick for your quick reply.For button i am doing exactly what you mentioned above,which is nothing but forceful rotate and locking.Now once its rotated how to unlock that rotation? — Arunabha Dutta Choudhury, Sep 22 '16 at 11:56
As per my understaing untill and unless i do something like this setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED); the locked rotation wont be unlocked — Arunabha Dutta Choudhury, Sep 22 '16 at 11:57
But where exactly i need to put that code after forceful rotation? — Arunabha Dutta Choudhury, Sep 22 '16 at 11:58
I changed my answer, now do you have enough info for your question? — 476rick, Sep 22 '16 at 12:04
Not really,i am now calling setAutoOrientationEnabled method from inside onConfigurationChanged,but the issue persist.Let me post my code here — Arunabha Dutta Choudhury, Sep 22 '16 at 12:41
