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.

    boolean performMultiPointerGesture (PointerCoords... touches)

    Performs a multi-touch gesture. You must specify touch coordinates for at least 2 pointers. Each pointer must have all of its touch steps defined in an array of MotionEvent.PointerCoords. You can use this method to specify complex gestures, like circles and irregular shapes, where each pointer may take a different path. To create a single point on a pointer's touch path: PointerCoords p = new PointerCoords(); p.x = stepX; p.y = stepY; p.pressure = 1; p.size = 1;

    Parameters
    percent int: percentage of the object's diagonal length for the pinch gesture
    steps int: the number of steps for the gesture. Steps are injected about 5 milliseconds apart, so 100 steps may take around 0.5 seconds to complete.

    Parameters
    percent int: percentage of the object's diagonal length for the pinch gesture
    steps int: the number of steps for the gesture. Steps are injected about 5 milliseconds apart, so 100 steps may take around 0.5 seconds to complete.

    setText

    boolean setText (String text)

    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.

    Parameters
    text String: string to set

    boolean true if operation is successful
    Throws
    UiObjectNotFoundException
    UiObjectNotFoundException
