使用如下构造函数

BasePage.java

import io.appium.java_client.AppiumDriver;
import io.appium.java_client.MobileElement;
import io.appium.java_client.android.AndroidElement;
import io.appium.java_client.pagefactory.AppiumFieldDecorator;
import org.openqa.selenium.support.PageFactory;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;

import java.time.Duration;

public class BasePage {

    public static AppiumDriver<MobileElement> driver;

    public BasePage(AppiumDriver<MobileElement> driver){
        this.driver = driver;;
        PageFactory.initElements(new AppiumFieldDecorator(driver, Duration.ofSeconds(10)), this);
    }

    public void waitForVisibility(AndroidElement e){
        WebDriverWait wait = new WebDriverWait(driver, TestUtils.WAIT);
        wait.until(ExpectedConditions.visibilityOf(e));
    }
    public String getAttribute(AndroidElement e, String attribute){
        waitForVisibility(e);
        return e.getAttribute(attribute);
    }
    public void sendKeys(AndroidElement e, String txt){
        waitForVisibility(e);
        e.sendKeys(txt);
    }
}

这称为页面对象模型。首先，使用 MobileElement 和 AndroidElement 这是错误的步骤，MobileElement 是最值得推荐的，因为适用于 android 和 ios。这个来源有更清晰的概念，访问https://blog.testproject.io/2018/07/31/page-object-model-appium-java-android/ check point number
