How to press a button twice using Google UiAutomator?

Question

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 ig

Answer 1

This issue seems to be built into the way UiObject is set up. As far as I can tell, an instance of UiObject doesn't seem to refer to a specific object on the screen. It's more like an instance of what's pointed to by the UiSelector when the UiObject was defined. The key here is that each time the object is called, it searches for a new item that fits the UiSelector requirements.

Evidence:

UiObject ok = new UiObject(new UiSelector().text("OK"));
ok.click();
// clicks a button with the text ok on the page
// Navigate to some different page with a button with the text ok
ok.click();
// this ok button on a completely different page is still clicked

Therefore, I think Rami's workaround might actually by the correct way to do it (store the location of the object through its coordinates and click on the center of that location). Important thing to note about Rami's workaround, save the coordinates/rectangle once and then reuse the coordinates/rectangle whenever you want to refer to the object. Using obj.getBounds() multiple times on the same object doesn't seem to work.

Also, records of the items that have already been passed over during a UiObject instantiation seem to be stored in the app. Running a test twice that finds a UiObject (ex. button 4 in the set alarm page) and clicks it fails the same way as a test that finds a UiObject and clicks it twice. This means that data of object queries must be stored on the device because resetting UIautomator makes no difference.

Answer 2

I found a small hack to go around the problem for now. get the boundaries everytime you run the test so its not device centric and will adapt on the fly.

UiObject obj1 = new UiObject(new UiSelector().text("4"));

  Rect four = obj1.getBounds();

  getUiDevice().click(four.centerX(), four.centerY());

Create a UiObject for 3 button and click twice.below is the snippet

UiObject three = new UiObject(new UiSelector().text("3"));
three.click();
three.click();

Answer 4

I have the same problem, looks like its looking for another UI element that have the same text. I'm trying to automate the creation of an Alarm but when the time is at for example 4:45 pm. Uiautomator will click the right Button.

 clickByText("4");
 clickByText("4");
 clickByText("5");
 clickByText("PM");
 clickByText("OK");

private void clickByText(String text) throws UiObjectNotFoundException {
            UiObject obj = new UiObject(new UiSelector().text(text));
            obj.click();
    }

Here is the Log for the first "4" click:

07-04 16:54:05.259: I/QueryController(25605): Matched selector: UiSelector[TEXT=4] <<==>> [android.view.accessibility.AccessibilityNodeInfo@592f1; boundsInParent: Rect(0, 0 - 202, 129); boundsInScreen: Rect(56, 508 - 258, 637); packageName: com.android.deskclock; className: android.widget.Button; text: 4; contentDescription: null; checkable: false; checked: false; focusable: true; focused: false; selected: false; clickable: true; longClickable: false; enabled: true; password: false; scrollable: false; [ACTION_FOCUS, ACTION_SELECT, ACTION_CLEAR_SELECTION, ACTION_CLICK, ACTION_ACCESSIBILITY_FOCUS, ACTION_NEXT_AT_MOVEMENT_GRANULARITY, ACTION_PREVIOUS_AT_MOVEMENT_GRANULARITY]]

Here is the Log for the second "4" click:

07-04 16:54:07.798: I/QueryController(25605): Matched selector: UiSelector[TEXT=4] <<==>> [android.view.accessibility.AccessibilityNodeInfo@5bffd; boundsInParent: Rect(0, 0 - 66, 90); boundsInScreen: Rect(191, 264 - 257, 354); packageName: com.android.deskclock; className: android.widget.TextView; text: 4; contentDescription: null; checkable: false; checked: false; focusable: false; focused: false; selected: false; clickable: false; longClickable: false; enabled: true; password: false; scrollable: false; [ACTION_SELECT, ACTION_CLEAR_SELECTION, ACTION_ACCESSIBILITY_FOCUS, ACTION_NEXT_AT_MOVEMENT_GRANULARITY, ACTION_PREVIOUS_AT_MOVEMENT_GRANULARITY]]

We can see that one is clicking the right android.widget.Button and the second click its looking for android.widget.TextView.

Answer 5

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));
}

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();

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

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

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