## Android 'UIScrollable' 滑动: 技巧和窍门 尽管Appium不允许你直接使用'UIScrollable'的所有能力，但可以通过忽略错误的技巧来充分利用'UIScrollable'的能力。 ### 向前滚动 ```java // scrollForward (精确滑动一个视图) try { driver.findElement(MobileBy.AndroidUIAutomator( "new UiScrollable(new UiSelector().scrollable(true)).scrollForward()")); } catch (InvalidSelectorException e) { // ignore } // flingForward (快速滑动) try { driver.findElement(MobileBy.AndroidUIAutomator( "new UiScrollable(new UiSelector().scrollable(true)).flingForward()")); } catch (InvalidSelectorException e) { // ignore } ``` ### 向后滚动 ```java // scrollBackward (精确滑动一个视图) try { driver.findElement(MobileBy.AndroidUIAutomator( "new UiScrollable(new UiSelector().scrollable(true)).scrollBackward()")); } catch (InvalidSelectorException e) { // ignore } // flingBackward (快速滑动) try { driver.findElement(MobileBy.AndroidUIAutomator( "new UiScrollable(new UiSelector().scrollable(true)).flingBackward()")); } catch (InvalidSelectorException e) { // ignore } ``` ### 滑到开始位置 ```java // scrollToBeginning (每次滑动一个视图，最多滑10次) try { driver.findElement(MobileBy.AndroidUIAutomator( "new UiScrollable(new UiSelector().scrollable(true)).scrollToBeginning(10)")); } catch (InvalidSelectorException e) { // ignore } // flingToBeginning (快速滑动，最多滑10次) try { driver.findElement(MobileBy.AndroidUIAutomator( "new UiScrollable(new UiSelector().scrollable(true)).flingToBeginning(10)")); } catch (InvalidSelectorException e) { // ignore } ``` ### 滑到结束位置 ```java // scrollToEnd (每次滑动一个视图，最多滑10次) try { driver.findElement(MobileBy.AndroidUIAutomator( "new UiScrollable(new UiSelector().scrollable(true)).scrollToEnd(10)")); } catch (InvalidSelectorException e) { // ignore } // flingToEnd (快速滑动，最多滑10次) try { driver.findElement(MobileBy.AndroidUIAutomator( "new UiScrollable(new UiSelector().scrollable(true)).flingToEnd(10)")); } catch (InvalidSelectorException e) { // ignore } ```
