线程“主”中的异常 org.openqa.selenium.StaleElementReferenceException：androidx.test.uiautomator.StaleObjectException

Question

我试图在 Android TV 上运行它，我看到 Appium 能够点击所有按钮并在文本框中输入数据，除了第一个按钮。我必须点击它然后等待并使用发送键来查看它是否解决了问题但没有运气。有人可以帮我吗。

Base.Java

import java.io.File;
import java.net.MalformedURLException;
import java.net.URL;

import org.openqa.selenium.remote.DesiredCapabilities;

import io.appium.java_client.android.AndroidDriver;
import io.appium.java_client.android.AndroidElement;
import io.appium.java_client.remote.MobileCapabilityType;

public class Base {
    
    public static AndroidDriver<AndroidElement> capabalities() throws MalformedURLException {
        
        File file = new File ("src");
        File fs = new File(file,"TVTestApp_ct.apk");
        
        DesiredCapabilities capabalities = new DesiredCapabilities();
        capabalities.setCapability(MobileCapabilityType.AUTOMATION_NAME,"uiautomator2");
        capabalities.setCapability(MobileCapabilityType.DEVICE_NAME, "Automation");
        capabalities.setCapability(MobileCapabilityType.APP, fs.getAbsolutePath());
        AndroidDriver<AndroidElement> driver = new AndroidDriver<AndroidElement>(new URL("http://127.0.0.1:4723/wd/hub"),capabalities);
        return driver;
    }

}

HomeScreen.Java

import java.net.MalformedURLException;

import org.openqa.selenium.By;
import org.openqa.selenium.By.ByClassName;
import org.openqa.selenium.StaleElementReferenceException;

import io.appium.java_client.MobileElement;
import io.appium.java_client.android.AndroidDriver;
import io.appium.java_client.android.AndroidElement;

public class HomeScreen extends Base {
    
    public static void main(String[] args) throws MalformedURLException, InterruptedException {
        
        AndroidDriver<AndroidElement> driver = capabalities();
        
        driver.findElementById("com.tvexample.tvtestapp:id/editText").sendKeys("1234");
        driver.findElementById("com.tvexample.tvtestapp:id/editText1").sendKeys("1234")         
        
    }


}

例子：

private void findUIByText(String t,String b,int n){
    Log.d(TAG,"findUIByText");
    //autoCheckAndClick.autoClick();
    int i = 0;
    UiObject2 object2 = null;
    while (i < 6) {
        i++;
        object2 = mDevice.findObject(
                By.textContains(t)
        );
        try {
            if(object2 != null){
                Log.d(TAG,"not null");
                if(Objects.equals(b, "TRUE")){
                    object2.click(1000);
                }else {
                    object2.click();
                }
                break;
            }

        } catch (StaleObjectException e) {
            Log.d(TAG,"StaleObjectException");
            if (n < 4){
                findUIByText(t,b,n+1);
            }
        }
        toSleep(500);

    }
}
