Change Screen Orientation programmatically using a Button

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

Android-Kotlin:

to make rotate X:

binding.btnRotateHorizontal.setOnClickListener {
     requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE
}

to make rotate Y:

binding.btnRotateVertical.setOnClickListener {
     requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED
}

mine worked with:

setLandscapeIcon.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
            setLandscapeIcon.setVisibility(View.GONE);
            setPortraitIcon.setVisibility(View.VISIBLE);
        }
    });

setPortraitIcon.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED);
                setLandscapeIcon.setVisibility(View.VISIBLE);
                setPortraitIcon.setVisibility(View.GONE);
            }
        });

In Manifest

android:configChanges = "orientation|screenSize"
android:screenOrientation="portrait"

NOTE: setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); was not working on my device

Yes ، Hariharan answer works fine . but you should add below line to AndroidManifest.xml in activity tag :

android:screenOrientation="fullSensor"
android:configChanges="orientation|screenSize"

if not add above line , Hariharan answer not work .

A working code:

private void changeScreenOrientation() {
    int orientation = yourActivityName.this.getResources().getConfiguration().orientation;
    if (orientation == Configuration.ORIENTATION_LANDSCAPE) {
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
        showMediaDescription();
    } else {
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
        hideMediaDescription();
    }
    if (Settings.System.getInt(getContentResolver(),
            Settings.System.ACCELEROMETER_ROTATION, 0) == 1) {
        Handler handler = new Handler();
        handler.postDelayed(new Runnable() {
            @Override
            public void run() {
                setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR);
            }
        }, 4000);
    }
}

call this method in your button click

Wherever possible, please don't use SCREEN_ORIENTATION_LANDSCAPE or SCREEN_ORIENTATION_PORTRAIT. Instead use:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_PORTRAIT);

These allow the user to orient the device to either landscape orientation, or either portrait orientation, respectively. If you've ever had to play a game with a charging cable being driven into your stomach, then you know exactly why having both orientations available is important to the user.

Note: For phones, at least several that I've checked, it only allows the "right side up" portrait mode, however, SENSOR_PORTRAIT works properly on tablets.

Note: this feature was introduced in API Level 9, so if you must support 8 or lower (not likely at this point), then instead use:

setRequestedOrientation(Build.VERSION.SDK_INT < 9 ?
                        ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE :
                        ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE);
setRequestedOrientation(Build.VERSION.SDK_INT < 9 ?
                        ActivityInfo.SCREEN_ORIENTATION_PORTRAIT :
                        ActivityInfo.SCREEN_ORIENTATION_SENSOR_PORTRAIT);

Yes it is implementable!

ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

ActivityInfo.SCREEN_ORIENTATION_PORTRAIT

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

ActivityInfo

http://developer.android.com/reference/android/content/pm/ActivityInfo.html

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);
   }

});

Yes, you can set the screen orientation programatically anytime you want using:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

for landscape and portrait mode respectively. The setRequestedOrientation() method is available for the Activity class, so it can be used inside your Activity.

And this is how you can get the current screen orientation and set it adequatly depending on its current state:

Display display = ((WindowManager) getSystemService(WINDOW_SERVICE)).getDefaultDisplay();
final int orientation = display.getOrientation(); 
 // OR: orientation = getRequestedOrientation(); // inside an Activity

// set the screen orientation on button click
Button btn = (Button) findViewById(R.id.yourbutton);
btn.setOnClickListener(new View.OnClickListener() {
          public void onClick(View v) {

              switch(orientation) {
                   case Configuration.ORIENTATION_PORTRAIT:
                       setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
                       break;
                   case Configuration.ORIENTATION_LANDSCAPE:
                       setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
                       break;                   
               }
          }
   });

EDIT

Also, you can get the screen orientation using the Configuration:

Activity.getResources().getConfiguration().orientation

Use this to set the orientation of the screen:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

or

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

and don't forget to add this to your manifest:

android:configChanges = "orientation"
