通过 Appium 获取 CSS 属性
Get CSS property via Appium
我只想单击启用“绿色”的按钮。为了找到按钮的颜色，我尝试了以下方法，但 none 有效并给出“UnsupportedCommandException”
MobileElement mobileElement = appiumDriver.findElement(By.xpath("//XCUIElementTypeButton[@name='Get Quote']"));
String color = mobileElement.getCssProperty("style");
String color = mobileElement.getCssProperty("background-color");
String color = mobileElement.getCssProperty("color");
异常：
org.openqa.selenium.UnsupportedCommandException: Unhandled endpoint: {
wildcards = (
"session/element/EF010000-0000-0000-8007-000000000000/css/background-color"
);

根据 Appium 文档：
Get Element CSS Value command only applies to webview contexts
https://appium.io/docs/en/commands/element/attributes/css-property/
因此它不适用于本机上下文。
检查元素是否启用
还有另一种检查按钮是否启用的方法：
https://appium.io/docs/en/commands/element/attributes/enabled
MobileElement mobileElement = appiumDriver.findElement(By.xpath("//XCUIElementTypeButton[@name='Get Quote']"));
if(mobileElement.isEnabled()) {
mobileElement.click();
}
检查元素颜色
如果您还需要验证元素颜色，您应该将页面（或元素）截图，然后获取元素位置，并尝试通过坐标获取屏幕截图上元素区域的像素颜色。
MobileElement mobileElement = appiumDriver.findElement(By.xpath("//XCUIElementTypeButton[@name='Get Quote']"));
File screenshot = ((TakesScreenshot)appiumDriver).getScreenshotAs(OutputType.FILE);
BufferedImage image = ImageIO.read(screenshot);
Point elementLocation = mobileElement.getLocation();
// Lets take color at point x=10, y=10 inside the element (0, 0 is the top left)
int checkColorX = elementLocation.getX() + 10;
int checkColorY = elementLocation.getY() + 10;
// Optionaly you may try to take not the page screenshot, but just the element screenshot
// File screenshot = mobileElement.getScreenshotAs(OutputType.FILE);
// BufferedImage image = ImageIO.read(screenshot);
// int checkColorX = 10;
// int checkColorY = 10;
// Getting pixel color by position x and y
int color = image.getRGB(checkColorX, checkColorY);
int red = (color & 0x00ff0000) >> 16;
int green = (color & 0x0000ff00) >> 8;
int blue = color & 0x000000ff;
System.out.println("Red Color value = "+ red);
System.out.println("Green Color value = "+ green);
System.out.println("Blue Color value = "+ blue);
// Then you need to compare each color with the values, you expect.
