我知道它有可能居preSSO通过边界的方式UiAutomator确实。 （x和y坐标），我已经通过文档阅读，但我似乎无法找到它。任何帮助是AP preciated。谢谢

I know it is possible for Espresso to click by bounds the way UiAutomator does. (x and y coordinates) I have read through the documentation but I can't seem to find it. Any help is appreciated. Thanks

修改 我发现此链接，但没有例子如何使用它，我主要关注的是这种 UiController 是，或如何使用它。

Edit I found this link, but no examples how to use it, My main concern with this is the UiController is or how to use it.

推荐答案

居preSSO有GeneralClickAction,这是ViewActions的底层实现点击（）， doubleClick如果（）和 longClick（ ）。

Espresso has the GeneralClickAction, this is the underlying implementation of ViewActions click(), doubleClick(), and longClick().

在 GeneralClickAction 的构造函数需要 CoordinatesProvider 作为第二个参数。 所以基本的想法是创建一个静态 ViewAction 吸气它提供了一个自定义的 CoordinatesProvider 。事情是这样的：

The GeneralClickAction's constructor takes a CoordinatesProvider as second argument. So the basic idea is to create a static ViewAction getter which provides a custom CoordinatesProvider. Something like this:

public static ViewAction clickXY(final int x, final int y){
    return new GeneralClickAction(
        Tap.SINGLE,
        new CoordinatesProvider() {
            @Override
            public float[] calculateCoordinates(View view) {

               final int[] screenPos = new int[2];
               view.getLocationOnScreen(screenPos);

               final float screenX = screenPos[0] + x;
               final float screenY = screenPos[1] + y;
               float[] coordinates = {screenX, screenY};

               return coordinates;
            }
        },
        Press.FINGER);
}

与长者preSSO一般的建议：与其找文件（有几乎没有），看看源$ C ​​$ C。居preSSO是开源和源$ C ​​$ C本身是真正的好品质。

A general advice with Espresso: instead of looking for documentation (there's virtually none), look at the source code. Espresso is open source and the source code itself is of really good quality.
