java - Java程序中的"driver cannot be resolved"

Question

我是编程世界的新手，所以我不知道如何解决这个问题。

`@Test
public void LoginEmail() {

    driver.findElement(By.id("email_button")).sendKeys("xxxxxxxx@gmail.com");`

在 driver.findElement 处，驱动程序带有红色下划线。当我将鼠标悬停在它上面时，这些就是我的选择。

无法复制选项，所以我截图了:

你应该先初始化它:

 try {
    WebDriver driver = new AndroidDriver();

    // And now use this to visit Google
    driver.get("http://www.google.com");

    // Find the text input element by its name
    WebElement element = driver.findElement(By.name("q"));

    // Enter something to search for
    element.sendKeys("Cheese!");

    // Now submit the form. WebDriver will find the form for us from the element
    element.submit();

    // Check the title of the page
    System.out.println("Page title is: " + driver.getTitle());
    driver.quit();
  } catch (Exception e) {
    e.printStackTrace();
  }
