用了 N 种方法都没有能够定位到。
先转到 webview 模式。

public void SwitchtoWebViewModel(AppiumDriver driver) throws Exception {
    try {
        Set<String> contextNames = driver.getContextHandles();
        for (String contextName : contextNames) {
            System.out.println(contextName);
            // 用于返回被测app是NATIVE_APP还是WEBVIEW，如果两者都有就是混合型App
            if (contextName.contains("WEBVIEW")) {
                driver.context(contextName);
                // appDriver.switchTo().window("WEBVIEW");
                break;
            }// end if
        }// end for

然后用 xpath，id，class 定位均告失败。

            SwitchtoWebViewModel(driver);
Sleeper.sleep();
driver.findElementByXPath("//div[@class='More']").click();

结果报错。

大神们，有没有办法定位 HTML5 元素的！！
