如何使用TouchAction滚动Appium 1.7.1

Question

在iOS和Android应用程序中，我无法向下滚动到某个元素。由于从Appium 1.6.3更新到1.7.1，从io.Appium更新到6.1.0，因此不推荐使用滑动方法，唯一的解决方案是使用TouchActions。

我试图用TouchActions解决它，但它根本没有滚动，或者滚动方向错误。

到目前为止，我的解决方案是这样的，也许有人能解释我做错了什么：

public void scrollDownUntilElementVisible(WebElement element){
    TouchAction touchAction = new TouchAction(getDriver());
    for(int i=0; i<dimensions.getHeight();i++){
       if(element.isDisplayed()){
          break;
       }else{
          touchAction.press(0,0).moveTo(element).release().perform();
       }
    }
}

这不是完整的代码，但我希望你明白。

如果我使用x，y坐标，而不是我在示例中寻找的webElement，它将如何工作？它不像以前版本中的swipe方法那样工作，或者我做得不对。也许有人能解释一下。

我需要滚动找到屏幕外的元素。我想到的是：

1. 在当前/可见屏幕上搜索所需元素。

private void scrollDown() {
    //if pressX was zero it didn't work for me
    int pressX = driver.manage().window().getSize().width / 2;
    // 4/5 of the screen as the bottom finger-press point
    int bottomY = driver.manage().window().getSize().height * 4/5;
    // just non zero point, as it didn't scroll to zero normally
    int topY = driver.manage().window().getSize().height / 8;
    //scroll with TouchAction by itself
    scroll(pressX, bottomY, pressX, topY);
}

/*
 * don't forget that it's "natural scroll" where 
 * fromY is the point where you press the and toY where you release it
 */
private void scroll(int fromX, int fromY, int toX, int toY) {
    TouchAction touchAction = new TouchAction(driver);
    touchAction.longPress(fromX, fromY).moveTo(toX, toY).release().perform();
}

另外，您可以从元素中获取坐标并在滚动中使用它。

P. S. S.我用了appium 1.6.5

在最新版本的Appium需要添加（PointOption.point同时传递坐标）一些使用TouchAction滚动的代码：

private void scrollDown() {
    //if pressX was zero it didn't work for me
    int pressX = driver.manage().window().getSize().width / 2;
    // 4/5 of the screen as the bottom finger-press point
    int bottomY = driver.manage().window().getSize().height * 4/5;
    // just non zero point, as it didn't scroll to zero normally
    int topY = driver.manage().window().getSize().height / 8;
    //scroll with TouchAction by itself
    scroll(pressX, bottomY, pressX, topY);
}



private void scroll(int fromX, int fromY, int toX, int toY) {
    TouchAction touchAction = new TouchAction(driver);
    touchAction.longPress(PointOption.point(fromX, fromY)).moveTo(PointOption.point(toX, toY)).release().perform();
}
