如何preSS使用谷歌UiAutomator两次按钮？ [英] How to press a button twice using Google UiAutomator?

问题描述

我有以下脚本输入33到计算器，在Android中，使用UiAutomator。但是，只有第一个3被接受，第二preSS被完全忽略。

I have the following script for typing '33' into the Calculator, in Android, using UiAutomator. However, only the first '3' is accepted, the second press is entirely ignored.

import com.android.uiautomator.core.*;
import com.android.uiautomator.testrunner.UiAutomatorTestCase;

public class MyFirstUiAutomatorTest extends UiAutomatorTestCase {
    UiObject getByDescription(String description) {
        return new UiObject(new UiSelector().description(description));
    }

    UiObject getByText(String description) {
        return new UiObject(new UiSelector().text(description));
    }

    UiObject scrollableGetByText(String text ) throws UiObjectNotFoundException {
            UiScrollable uiScrollable = new UiScrollable(new UiSelector().scrollable(true));
            uiScrollable.setAsHorizontalList();
            return uiScrollable.getChildByText(new UiSelector().className(
                    android.widget.TextView.class.getName()),
                    text);      
    }

    public void testStuff() throws UiObjectNotFoundException {
        getUiDevice().pressHome();
        getByDescription("Apps").clickAndWaitForNewWindow();
        getByText("Apps").click();
        scrollableGetByText("Calculator").clickAndWaitForNewWindow();

        // pressing '+' and '=' effectively clears the previous input
        getByText("+").click();
        getByText("=").click();
        getByText("3").click();
        // this second '3' is ignored
        getByText("3").click();
    }
}

我已经尝试添加一个睡眠2秒后，第一次点击，这样做：

I've tried adding a sleep for 2 seconds after the first click, by doing:

        try {
            Thread.sleep(2000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

...但是，这并没有改变任何东西。

... but that didn't change anything.

我也试过2之间点击不同的按钮，在3的，即：

I also tried clicking on a different button, in between the 2 '3's, ie:

        new UiObject(new UiSelector().text("3")).click();
        new UiObject(new UiSelector().className("android.widget.EditText")).click();
        new UiObject(new UiSelector().text("3")).click();

...但是，这也不能工作。

... but that didn't work either.

想法？

（注：采用Android 4.1.2，在AVD;在Ubuntu Linux上运行12.04）

(Note: using Android 4.1.2, in an AVD; running on Ubuntu linux 12.04)

编辑，下面拉米的意见，我尝试以下，重复使用相同的UIObject的对象第二次请求相同的说明：

Edit, following Rami's observations, I tried the following, to reuse the same UiObject object for a second request for the same description:

HashMap<String,UiObject> objectByText = new HashMap<String,UiObject>(); 
UiObject getByText(String description) {
    if( objectByText.containsKey(description)) {
        System.out.println("" + objectByText.get(description) );
        return objectByText.get(description);
    }
    System.out.println("Created new object for [" + description + "]");
    UiObject object = new UiObject(new UiSelector().text(description));
    objectByText.put(description, object );
    System.out.println("" + object );
    return object;
}

...但它没有工作，即使它每一次明确地重复使用相同的UIObject的，因为它只是说为创建新的对象[3]一次。

... but it didn't work, even though it is clearly reusing the same UiObject each time, because it only says 'Created new object for [3]' once.

然后我尝试了UiDevice.click（）'把戏'，通过创建功能点击如下，再次，下面拉米的看法：

Then I tried the UiDevice.click() 'trick', by creating a function 'click' as follows, again, following Rami's observations:

void click(UiObject target ) throws UiObjectNotFoundException {
    Rect rect = target.getBounds();
    System.out.println("rect: " + rect );
    getUiDevice().click(rect.centerX(), rect.centerY());
}

无论是

不过，这并没有为我工作：只有第一个3出现，第二个被忽略，即使两者的点击都清楚地在同一个地方，因为 RECT：输出位置是相同的。如果我点击'3'两次手工，用我自己的桌面鼠标，那么这两个三分球出现ok了。

However, this didn't work for me either: only the first '3' appears, and the second is ignored, even though both clicks are clearly in the same place, because the rect: output locations are identical. If I click '3' twice manually, using my own desktop mouse, then both 3s appear ok.

我也尝试添加两秒钟的视频下载（）的点击之间，仍然只有一个3出现了我。

I also tried adding a two second Thread.sleep() between the clicks, and still only a single '3' appeared for me.

推荐答案

而不是通过文字只是在寻找，试图通过文字和类搜索。 下面是这样做的一个抽样的方法。

Instead of just searching by text, try searching by the text and the class. Here is a sample method for doing so.

Uiobject getByTextAndClass(String text, String className) {
    return new UiObject(new UiSelector().text(text).className(className));
}

然后，如果你试图调用此方法的计算器按钮3号就可以了：

And then if you are trying to call this method for the Calculator button with number 3 on it:

getByTextAndClass("3", android.widget.Button.class.getName()).click();

您可以使用UiAutomatorViewer工具：{Android的SDK} /tool​​s/uiautomator.bat检查类名和不同UiObjects的其他属性。

You can use the UiAutomatorViewer tool: {android-sdk}/tools/uiautomator.bat to check the classnames and other attributes of different UiObjects.

这工作对我的4.2.2的设备，但我下载4.1.2对有作为对其进行测试。

This works on my 4.2.2 devices, but I am downloading 4.1.2 to test it on there as well.

我试了一下在4.1.2 AVD和它的作品在我的Windows机器上。

I tried it on a 4.1.2 AVD and it works on my Windows machine.
