## 简单的元素Swipe ### Android的UIAutomator2 默认的UIAutomator2只返回在屏幕上可以看到的元素。如果可见视图和不可见视图分隔了某个容器，那么此容器中一部分内容将无法（被UIAutomator2）识别到。  ```java /** * Performs swipe inside an element * * @param el the element to swipe * @param dir the direction of swipe * @version java-client: 7.3.0 **/ public void swipeElementAndroid(MobileElement el, Direction dir) { System.out.println("swipeElementAndroid(): dir: '" + dir + "'"); // always log your actions // Animation default time: // - Android: 300 ms // - iOS: 200 ms // final value depends on your app and could be greater final int ANIMATION_TIME = 200; // ms final int PRESS_TIME = 200; // ms int edgeBorder; PointOption pointOptionStart, pointOptionEnd; // init screen variables Rectangle rect = el.getRect(); // sometimes it is needed to configure edgeBorders // you can also improve borders to have vertical/horizontal // or left/right/up/down border variables edgeBorder = 0; switch (dir) { case DOWN: // from up to down pointOptionStart = PointOption.point(rect.x + rect.width / 2, rect.y + edgeBorder); pointOptionEnd = PointOption.point(rect.x + rect.width / 2, rect.y + rect.height - edgeBorder); break; case UP: // from down to up pointOptionStart = PointOption.point(rect.x + rect.width / 2, rect.y + rect.height - edgeBorder); pointOptionEnd = PointOption.point(rect.x + rect.width / 2, rect.y + edgeBorder); break; case LEFT: // from right to left pointOptionStart = PointOption.point(rect.x + rect.width - edgeBorder, rect.y + rect.height / 2); pointOptionEnd = PointOption.point(rect.x + edgeBorder, rect.y + rect.height / 2); break; case RIGHT: // from left to right pointOptionStart = PointOption.point(rect.x + edgeBorder, rect.y + rect.height / 2); pointOptionEnd = PointOption.point(rect.x + rect.width - edgeBorder, rect.y + rect.height / 2); break; default: throw new IllegalArgumentException("swipeElementAndroid(): dir: '" + dir + "' NOT supported"); } // execute swipe using TouchAction try { new TouchAction(driver) .press(pointOptionStart) // a bit more reliable when we add small wait .waitAction(WaitOptions.waitOptions(Duration.ofMillis(PRESS_TIME))) .moveTo(pointOptionEnd) .release().perform(); } catch (Exception e) { System.err.println("swipeElementAndroid(): TouchAction FAILED\n" + e.getMessage()); return; } // always allow swipe action to complete try { Thread.sleep(ANIMATION_TIME); } catch (InterruptedException e) { // ignore } } ``` ### iOS的XCUITest XCUITest可以显示屏幕外的元素。强烈建议使用屏幕滑动(screen swipe)或'mobile:scroll' / 'mobile:swipe' 方法。如果你需要或更倾向于使用元素相关的方法，需要考虑以下内容： 1. 检查确保起始点和结束点都在屏幕区域之内。 2. 滚动视图通常是背景元素。页面/页脚或其他元素覆盖在滚动视图之上，限制了滚动性。尝试配置正确的边界以保证滚动性。如果不同屏幕上的边界有差异，应该通过swipe方法的参数进行配置化处理。 ```java /** * Performs swipe inside an element * * @param el the element to swipe * @param dir the direction of swipe * @version java-client: 7.3.0 **/ public void swipeElementIOS(MobileElement el, Direction dir) { System.out.println("swipeElementIOS(): dir: '" + dir + "'"); // always log your actions // Animation default time: // - Android: 300 ms // - iOS: 200 ms // final value depends on your app and could be greater final int ANIMATION_TIME = 200; // ms final int PRESS_TIME = 500; // ms // init screen variables Dimension dims = driver.manage().window().getSize(); Rectangle rect = el.getRect(); // check element overlaps screen if (rect.x >= dims.width || rect.x + rect.width <= 0 || rect.y >= dims.height || rect.y + rect.height <= 0) { throw new IllegalArgumentException("swipeElementIOS(): Element outside screen"); } // init borders per your app screen // or make them configurable with function variables int leftBorder, rightBorder, upBorder, downBorder; leftBorder = 0; rightBorder = 0; upBorder = 0; downBorder = 0; // find rect that overlap screen if (rect.x < 0) { rect.width = rect.width + rect.x; rect.x = 0; } if (rect.y < 0) { rect.height = rect.height + rect.y; rect.y = 0; } if (rect.width > dims.width) rect.width = dims.width; if (rect.height > dims.height) rect.height = dims.height; PointOption pointOptionStart, pointOptionEnd; switch (dir) { case DOWN: // from up to down pointOptionStart = PointOption.point(rect.x + rect.width / 2, rect.y + upBorder); pointOptionEnd = PointOption.point(rect.x + rect.width / 2, rect.y + rect.height - downBorder); break; case UP: // from down to up pointOptionStart = PointOption.point(rect.x + rect.width / 2, rect.y + rect.height - downBorder); pointOptionEnd = PointOption.point(rect.x + rect.width / 2, rect.y + upBorder); break; case LEFT: // from right to left pointOptionStart = PointOption.point(rect.x + rect.width - rightBorder, rect.y + rect.height / 2);
