imageview motion event EnumCommands

I am building an application that controls a computer through an Android device till now I have finished the computer Java side and i have finished most of the android code that receives the image stream in ImageView .
So i made EnumCommands as following :

public enum EnumCommands {
    PRESS_MOUSE(-1),
    RELEASE_MOUSE(-2),
    PRESS_KEY(-3),
    RELEASE_KEY(-4),
    MOVE_MOUSE(-5);

    private int abbrev;

    EnumCommands(int abbrev){
        this.abbrev = abbrev;
    }

    public int getAbbrev(){
        return abbrev;
    }
}

then in the main activity i tried to make the touch listeners to the ImageView
as MotionEvent.ACTION_DOWN , MotionEvent.ACTION_MOVE ,

case MotionEvent.ACTION_MOVE:
				int x_cord = (int) event.getRawX();
				int y_cord = (int) event.getRawY();

				if (x_cord > windowwidth) {
					x_cord = windowwidth;
				}
				if (y_cord > windowheight) {
					y_cord = windowheight;
				}

				layoutParams.leftMargin = x_cord - 25;
				layoutParams.topMargin = y_cord - 75;

				IV.setLayoutParams(layoutParams);
				break;

So what i need is code for all the touch and motion events and the EnumCommands for my this project.
