JAVA+Appium 自动化实现手机屏幕滑动点击操作

背景：App某些页面元素无法通过Appium或其他方式抓取到，无法通过传统方式定位到元素。

原理：获取到当前屏幕的尺寸，在要操作的元素的屏幕位置构造像素点位，进而执行点击或滑动操作。

注：坐标定位时采用相对定位方式，可适配其他分辨率。

1、坐标点击屏幕元素

<dependency>
<groupId>io.appium</groupId>
<artifactId>java-client</artifactId>
<version>7.1.0</version>
</dependency>

<dependency>
<groupId>org.testng</groupId>
<artifactId>testng</artifactId>
<version>6.10</version>
<scope>test</scope>
</dependency>

前提准备：连接驱动设备

public DesiredCapabilities getCapabilities() {
       DesiredCapabilities desiredCapabilities = new DesiredCapabilities();
    desiredCapabilities.setCapability("platformName", "Android");
    desiredCapabilities.setCapability("platformVersion", "9");
    desiredCapabilities.setCapability("deviceName", "923QEDUK22434");
    desiredCapabilities.setCapability("appPackage", "com.leke.lekechat");
    desiredCapabilities.setCapability("appActivity", "com.leke.lekechat.ui.SplashFirstActivity");
    desiredCapabilities.setCapability("automationName", "UiAutomator2");
    desiredCapabilities.setCapability("noReset", "True");
   return desiredCapabilities;
  }
  
  public AndroidDriver  getDriver() {
   private static final String APPIUM_SERVER_REMOTE = "http://localhost:4723/wd/hub";
   DesiredCapabilities desiredCapabilities =this.getCapabilities();
   URL remoteUrl = null;
   try {
    remoteUrl = new URL(APPIUM_SERVER_REMOTE);
    driver = new AndroidDriver(remoteUrl, desiredCapabilities);
   } catch (MalformedURLException e) {
    e.printStackTrace();
   }
   return driver;
  }

实现点击：

public void clickElement_OverScreen( AndroidDriver driver,int [ ][ ]  arr) {
  TouchAction ta = new TouchAction(driver);
        int width = driver.manage().window().getSize().width;
        int height = driver.manage().window().getSize().height;    
        int P_base_X=arr[0][0];   //元素基准位置坐标
        int P_base_y=arr[0][1];
        int P_base_Screen_X=arr[1][0];//元素所在页的屏幕基准尺寸
        int P_base_Screen_Y=arr[1][1];
        int point_X=this.formatNumber(P_base_X, P_base_Screen_X, width);
        int point_Y=this.formatNumber(P_base_y, P_base_Screen_Y, height);
        PointOption point_Concat=PointOption.point(point_X,point_Y);
        ta.press(point_Concat).release().perform();
  
 }


public int formatNumber(int P_1,int P_2,int P_3) {
         float dd=(float)P_1/(float)P_2;
         DecimalFormat df = new DecimalFormat("0.00000000");//格式化小数，不足的补0 
         String rat = df.format((double)dd);
         float ff=Float.parseFloat(rat);
         int formatNum =(int) (ff*P_3);
        return  formatNum;
 }

示例：

    @Test
 public void clickElement_1() {
        //arr[0]:当前屏幕上元素的坐标；arr[1]:当前屏幕的分辨率
  int[][] keyboardArr = { { 980, 2050 }, { 1080, 2098 } }; //手机键盘的搜索按钮坐标
  AndroidDriver driver = this.getDriver();
  this.clickElement_OverScreen(driver, keyboardArr); //屏幕构造坐标点位并点击
  
 }

2、滑动屏幕

public void executeSlide(AndroidDriver driver,int [ ][ ]  arr) {
  TouchAction ta = new TouchAction(driver);
        int width = driver.manage().window().getSize().width;//当前屏幕的宽度
        int height = driver.manage().window().getSize().height; //当前屏幕的高度
      //new一个TouchAction对象，调用其按压press()方法，输入坐标点,moveTo移动到下一个坐标点，之后调用release()和perform()方法执行
        PointOption P_B=   PointOption.point(width*arr[0][0]/arr[0][1], height*arr[1][0]/arr[1][1]);
        PointOption P_N=   PointOption.point(width*arr[2][0]/arr[2][1], height*arr[3][0]/arr[3][1]);
        WaitOptions waitOption = WaitOptions.waitOptions(Duration.ofSeconds(1));//设置动作持续时间：按压一秒
        ta.press(P_B).waitAction(waitOption).moveTo(P_N).release().perform();//按压一秒——移动——松开释放
 }
 @Test
 public void clickElement_1() {
  //表示沿X轴平移——左滑（0.9X-->0.3X） Y轴坐标为屏幕height的0.8倍
  int[][] arr = { { 9, 10 }, { 4, 5 }, { 3, 10 }, { 4, 5 } };
  AndroidDriver driver = this.getDriver();
  this.executeSlide(driver, arr);
  
 }
