appium等待控件或者Activity出现函数

UI执行过程中，需要判断控件或者想要进入的Activity是否出现，然后在进行其他操作

public class WaitUtils extends BaseTest{public static final Logger log = Logger.getLogger(WaitUtils.class);public static void waitForLoadingElementbyId(String elementID) {int i = 0;while (i<5) {try {if (driver.findElement(By.id(elementID)).isDisplayed()) {log.info(elementID+",控件已出现！");break;}} catch (Exception e) {log.info(elementID+",控件未出现！Waitting.........");i++;}}if(i==4)log.info(elementID+"控件尝试五次都没出现");}public static void waitForLoadingActivity(String ActivityName) {int i =0;SleepUtil.sleep(3000);while (i<5) {try {if (ActivityName.contains(driver.currentActivity())) {log.info(ActivityName+"出现！");break;}else{log.info(ActivityName+"未出现！Waitting.........1s");SleepUtil.sleep(1000);i++;}} catch (Exception e) {i++;log.info(ActivityName+",未出现！Waitting......... 随机时间");}}}}
