浓咖啡:如何进行自定义滑动，例如在顶部滑动或在底部滑动 [英] Espresso: How to do custom swipe e.g. swipeTop or swipeBottom

问题描述

到目前为止，我们可以做到:

So far we can do:

• swipeLeft
• swipeRight
• swipeUp
• swipeDown

我们如何swipeTop(一直到顶部)或swipeBottom(一直到底部)是表情.如果这些方法已经存在，请举个例子.

How can we swipeTop(all the way to the Top) or swipeBottom(all the way to the bottom) is expresso. Please give me an example if these methods already exists.

推荐答案

您是否尝试过这样的GeneralSwipeAction?

private static ViewAction swipeFromTopToBottom() {
    return new GeneralSwipeAction(Swipe.FAST, GeneralLocation.TOP_CENTER,
            GeneralLocation.BOTTOM_CENTER, Press.FINGER);
}

也许您必须为第二个和/或第三个参数提供自定义实现，就像安娜已经提到的那样:

Maybe you have to provide a custom implementation for the second and/or third parameter, as Anna already mentioned:

new CoordinatesProvider() {
    @Override
    public float[] calculateCoordinates(View view) {
        float[] coordinates =  GeneralLocation.CENTER.calculateCoordinates(view);
        coordinates[1] = 0;
        return coordinates;
    }
}
