Public constructors

ViewActions

public ViewActions()

Public methods

actionWithAssertions

public static ViewAction actionWithAssertions(ViewAction viewAction)

Performs all assertions before the ViewActions in this class and then performs the given ViewAction

Parameters
ViewAction viewAction

the ViewAction to perform after the assertions

addGlobalAssertion

public static void addGlobalAssertion(String name, ViewAssertion viewAssertion)

Adds a ViewAssertion to be run every time a ViewAction in this class is performed. The assertion will be run prior to performing the action.

Parameters
String name

a name of the assertion to be added

ViewAssertion viewAssertion

a ViewAssertion to be added

Throws
java.lang.IllegalArgumentException java.lang.IllegalArgumentException

if the name/viewAssertion pair is already contained in the global assertions.

clearGlobalAssertions

public static void clearGlobalAssertions()

clearText

public static ViewAction clearText()

Returns an action that clears text on the view. View constraints:

  • must be displayed on screen

click

public static ViewAction click()

Same as click(int inputDevice, int buttonState), but uses SOURCE_UNKNOWN as the inputDevice and MotionEvent#BUTTON_PRIMARY as the buttonState.

click

public static ViewAction click(ViewAction rollbackAction)

Returns an action that performs a single click on the view.

If the click takes longer than the 'long press' duration (which is possible) the provided rollback action is invoked on the view and a click is attempted again.

This is only necessary if the view being clicked on has some different behaviour for long press versus a normal tap.

For example - if a long press on a particular view element opens a popup menu - ViewActions.pressBack() may be an acceptable rollback action. View constraints:

  • must be displayed on screen
  • any constraints of the rollbackAction

click

public static ViewAction click(int inputDevice, int buttonState)

Returns an action that clicks the view for a specific input device and button state.

source input device of the click. Example: InputDevice#SOURCE_MOUSE

int buttonState

buttonState associated with the click. Example: BUTTON_PRIMARY
