UiObject
class UiObject
UiCollection |
Used to enumerate a container's UI elements for the purpose of counting, or targeting a sub elements by a child's text or description. |
UiScrollable |
UiScrollable is a |
A UiObject is a representation of a view. It is not in any way directly bound to a view as an object reference. A UiObject contains information to help it locate a matching view at runtime based on the UiSelector properties specified in its constructor. Once you create an instance of a UiObject, it can be reused for different views that match the selector criteria.

setText
fun setText(text: String?): Boolean
Sets the text in an editable field, after clearing the field's content.
The UiSelector selector of this object must reference a UI element that is editable.
When you call this method, the method sets focus on the editable field, clears its existing content, then injects your specified text into the field.
If you want to capture the original contents of the field, call getText first. You can then modify the text and use this method to update the field.
Improvements: Post API Level 19 (KitKat release), the underlying implementation is updated to a dedicated set text accessibility action, and it also now supports Unicode.

waitForExists
fun waitForExists(timeout: Long): Boolean
Waits a specified length of time for a view to become visible. This method waits until the view becomes visible on the display, or until the timeout has elapsed. You can use this method in situations where the content that you want to select is not immediately displayed.
| Parameters | |
|---|---|
timeout: Long |

timeout: Long |
time to wait (in milliseconds) |
| Returns | |
|---|---|
Boolean |
