Returns
ViewAction

addGlobalAssertion

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
name String: a name of the assertion to be added

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

clearGlobalAssertions

void clearGlobalAssertions ()

clearText

ViewAction clearText ()

Returns an action that clears text on the view.

View constraints:

click

ViewAction click ()

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

click

ViewAction click (int inputDevice, 
                int buttonState)

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

Note: Not supported by API < 14. An UnsupportedOperationException will be thrown if called on API < 14. For API < 14, call click() instead.

View constraints:

click

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.
