Dynamically rotate buttons in landscape view

I am working with OpenCV in android. I am forced to use 

android:screenOrientation="landscape"

in my AndroidManifest.xml

The problem I am facing is that I want to rotate only one Button according to screen orientation. The rest must remain un rotated.

Is that possible?
Will the line I added to Manifest File prevent detection of all future rotations?

you need to provide layout for that.

for Example. 

res
    layout
        main.xml
    layout-land
        main.xml

Now create your layout you want under -land folder. And it will load when phone is rotate.

Feel free to ask anything.

Yes the line added prevent all rotations.

You can create a new folder under /res , called 'layout-land' (without quotes), copy your layout to these folder and modify. Android read layout folder to protait orientation, and layout-land to show the layout landscape orientation.

You can leverage the Position Sensor as described in this article (Position Sensor) to determine the orientation of your phone.

With that, you can get the angle in onSensorChanged() as following.

@Override
  public void onSensorChanged(SensorEvent event) {
    float azimuth_angle = event.values[0];
    float pitch_angle = event.values[1];
    float roll_angle = event.values[2];
    // Do something with these orientation angles.
  }

Hope this helps.
