Some time we need to scroll (swap ) screen to scroll application, it can be left, right up and down. You can use following function to achieve this.

public void scrollFormCenter(String direction) {

                         Dimension size = driver.manage().window().getSize();

                         switch (direction) {

                         case "up":

                                             int x = size.width / 2;

                                             int endy = (int) (size.height * 0.75);

                                             int starty = (int) (size.height * 0.20);

                                             driver.swipe(x, starty, x, endy, 1000);

                                             break;

                         case "down":

                                             x = size.width / 2;

                                             starty = (int) (size.height * 0.75);

                                             endy = (int) (size.height * 0.20);

                                             driver.swipe(x, starty, x, endy, 1000);

                                             break;

                         case "left":

                                             int y = (int) size.height / 2;

                                             int startx= (int) (size.width * 0.15);

                                             int endx  = (int) (size.width * 0.75);

                                             driver.swipe(startx, y, endx, y, 1000);

                                             break;

                         case "right":

                                             y = (int) size.height / 2;

                                             endx = (int) (size.width * 0.15);

                                             startx = (int) (size.width * 0.85);

                                             driver.swipe(startx, y, endx, y, 1000);

                                             break;

                         }

    }

Call this function in your code like below:

scrollFormCenter(down)               //for scrolling down

scrollFormCenter(left)                    //for scrolling down

scrollFormCenter(right)                  //for scrolling down
