Change Screen Orientation programmatically using a Button

Question

I think this is implementable since screen rotation behaviour can go up to the application level.

Answer 1

Yes it is implementable!

ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); 

ActivityInfo.SCREEN_ORIENTATION_PORTRAIT

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

Refer the link:

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);    }  });
