Create four new global float variable x_cord, y_cord, x_cordIn & y_cordIn.

ainerLayout.setOnTouchListener(new OnTouchListener() {

    private long startClickTime;
    private float x1;
    private float y1;
    private float x2;
    private float y2;
    private float _dx;
    private float _dy;

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        boolean defaultResult = v.onTouchEvent(event);
        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                x_cord = x_cordIn = event.getRawX();
                y_cord = y_cordIn = event.getRawY();

                x1 = (int) event.getRawX();
                y1 = (int) event.getRawY();

                this.startClickTime = Calendar.getInstance().getTimeInMillis();
                return true;

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

                float xPos = myRelView.getX() - (x_cordIn - x_cord);
                float yPos = myRelView.getY() - (y_cordIn - y_cord);

                CardView_new.this.setX(xPos);
                CardView_new.this.setY(yPos);

                if (x_cord >= screenCenter) {

                    /**
