appium一些util 判断元素是否存在 以及 滑动

//判断元素id是否存在

public static boolean isElementExist(AndroidDriver driver,By by) {

try {
driver.findElement(by);
return true;
}catch(Exception e) {
return false;
}

}

//判断text是否存在

public boolean isElementExistTest(AndroidDriver driver,String name ){
        try{
            driver.findElement(By.name(name));
            return true;
        }catch(Exception ex){
        System.out.println(name+"不存在");
        ex.printStackTrace();
            return false;
        }
    }

if (num.isElementExist(driver, "XXXXXXXXXXXXXXXXXXX")==true) {
driver.swipe(820, 681, 820, 411, 500);
Thread.sleep(500);
driver.swipe(952, 460, 820, 630, 500);
Thread.sleep(500);
driver.swipe(1072, 460, 1072, 630, 500);
Thread.sleep(500);
} else {
System.out.println("会员登录错误");
