如何从混合应用程序获取 AppiumDriver 中的 Web 元素？

Question

我正在尝试使用 appium 和 selenium 自动化 Cordova 构建混合应用程序。

但是，我无法使用

获取任何元素

driver.findElement(By.id("xxx"));

当我使用

进行 pageSource 转储时

String pageSource = driver.getPageSource();

    System.out.print("*************dumping: ***********\n"+pageSource+"\n\n\n");

我得到

<?xml version="1.0" encoding="UTF-8"?><hierarchy rotation="0"><android.widget.FrameLayout index="0" text="" class="android.widget.FrameLayout" package="com.alarmforce.connect.client.keypad" content-desc="" checkable="false" checked="false" clickable="false" enabled="true" focusable="false" focused="false" scrollable="false" long-clickable="false" password="false" selected="false" bounds="[0,0][1024,552]" resource-id="" instance="0"><android.widget.LinearLayout index="0" text="" class="android.widget.LinearLayout" package="com.alarmforce.connect.client.keypad" content-desc="" checkable="false" checked="false" clickable="false" enabled="true" focusable="false" focused="false" scrollable="false" long-clickable="false" password="false" selected="false" bounds="[0,0][1024,552]" resource-id="" instance="0"><android.widget.FrameLayout index="0" text="" class="android.widget.FrameLayout" package="com.alarmforce.connect.client.keypad" content-desc="" checkable="false" checked="false" clickable="false" enabled="true" focusable="false" focused="false" scrollable="false" long-clickable="false" password="false" selected="false" bounds="[0,25][1024,552]" resource-id="android:id/content" instance="1"><android.webkit.WebView index="0" text="" class="android.webkit.WebView" package="com.alarmforce.connect.client.keypad" content-desc="Web View" checkable="false" checked="false" clickable="true" enabled="true" focusable="true" focused="true" scrollable="false" long-clickable="false" password="false" selected="false" bounds="[0,25][1024,552]" resource-id="" instance="0"/></android.widget.FrameLayout></android.widget.LinearLayout></android.widget.FrameLayout></hierarchy>

如何使它以 HTML 格式显示，就像我连接设备时在 chrome://inspect 中显示的那样？

我试过了：

 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        WebView.setWebContentsDebuggingEnabled(true);
    }

在MainActivity.java

我也试过：

driver.context("web_view");

能力：

DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("platformName", "Android");
capabilities.setCapability("deviceName","xxxxxxx");
capabilities.setCapability("platformVersion", "4.4");
driver = new AndroidDriver<>(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);

Answer 1

使用 appium 切换上下文的一个好方法是：

Set<String> contextNames = driver.getContextHandles();
String setContext = contextNames.toArray()[1].toString(); //generally your WEBVIEW context if available
driver.context(setContext);// set context to the webview name in string format

Answer 2

感谢nullpointer，问题解决！！！对于遇到此问题的任何人，请尝试以下操作：

    System.out.print("*************dumping source before setContext(unusable stuff): *************\n"+driver.getPageSource()+"\n\n\n"); 


    Set<String> contextNames = driver.getContextHandles();
    String setContext = contextNames.toArray()[1].toString(); //generally your WEBVIEW context if available
    driver.context(setContext);// set context to the webview name in string format

    System.out.print("*************dumping source after setContext(useful stuff): *************\n"+driver.getPageSource()+"\n\n\n");
