Click on not fully visible imageButton with Espresso

I don't think there is any easy, elegant solution to this. The 90% constraint is hardcoded in GeneralClickAction, and the class is final so we can't override getConstraints.

I would write your own ViewAction based on GeneralClickAction's code, skipping the isDisplayingAtLeast check.

None of the above worked for me. Here is a custom matcher that completely removes that constraint and allows you to click on the view

 onView(withId(yourID)).check(matches(allOf( isEnabled(), isClickable()))).perform(
            new ViewAction() {
                @Override
                public Matcher<View> getConstraints() {
                    return ViewMatchers.isEnabled(); // no constraints, they are checked above
                }

                @Override
                public String getDescription() {
                    return "click plus button";
                }

                @Override
                public void perform(UiController uiController, View view) {
                    view.performClick();
                }
            }
    );
