按边界/坐标单击 [英] Click by bounds / coordinates
问题描述
我知道 Espresso 可以按边界点击 UiAutomator 可以.(x 和 y 坐标)我已经通读了文档,但似乎找不到它.任何帮助表示赞赏.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
编辑
我发现 这个链接,但没有示例如何使用它,我主要关心的是 UiController
是什么或如何使用它.
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
Espresso 有 GeneralClickAction
,这是ViewActions的底层实现click()
、doubleClick()
和 longClick()
.
Espresso has the GeneralClickAction
, this is the underlying implementation of ViewActions click()
, doubleClick()
, and longClick()
.
GeneralClickAction
的构造函数将 CoordinatesProvider
作为第二个参数.所以基本的想法是创建一个静态的 ViewAction
getter,它提供一个自定义的 CoordinatesProvider
.像这样:
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);
}
关于 Espresso 的一般建议:与其寻找文档(几乎没有),不如查看源代码.Espresso 是开源的,源代码本身质量非常好.
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.
